| San Antonio Area Roads History
|This page last updated July 14, 2018
is the best history of the San Antonio area
freeway system that I can assemble. The information on this page was
compiled from a wide variety of sources including old city maps,
articles, and an array of highway plans and documents. Many thanks to
the San Antonio Central Library Texana section and the San Antonio
district office of TxDOT for their assistance in
locating those materials.
page covers the history of the expansion of
the overall system but not capacity expansions on individual freeways.
Details of those capacity and reconstruction projects are available on
the individual freeway pages elsewhere on this site.
of US and state highways in downtown San Antonio and the
growth of automobile traffic in the 1930s caused severe congestion in
the central city. To
address this growing problem,
began planning a series of "interregional highways" in the late '30s to
traffic around downtown. However, the outbreak of World War II delayed
this initiative. After
the war ended in 1945, the effort resumed with a
civic and business leaders in late 1946 where "the development of an
interregional highway system in the San Antonio area" to help relieve
increasing congestion on downtown streets was discussed.
The manifestation of that was a 20-year master plan to ensure that San
Antonio was at or near the front of the line to receive post-war state
and federal funding to build an expressway system. City maps from as
as the mid-1940s show a three-legged "Interstate
Highways and Expressways for post-war construction" that is today's
"Downtown Y" of Interstates 10 and 35. In plans and
news reports, the routes were interchangeably referred to as
expressways; urban expressways; freeways; or interregional, intrastate,
or interstate highways.
first master plan and resulting civic and political support helped San
Antonio and Bexar County obtain voter approval for numerous bonds over
the years to purchase right-of-way for the future expressways. It was
this local cost-sharing that allowed San Antonio to leverage copious
state and federal funds that propelled the construction of local
expressways and landed San
Antonio one of the Texas Highway Department's four
Expressways divisions (the others being Houston, Dallas, and Ft.
Worth). As a result, by 1965, Bexar County had nearly 180
miles of Interstates
and expressways, a "metropolitan highway complex that...ranks
second only to Los Angeles" according to a San Antonio Express
and News report from 1966.
numerous freeway proposals were put forward. Not all of them
were implemented and a couple died due to public opposition, but most
were eventually built in one form or another, leading to the
comprehensive system that is in place
are maps and descriptions of the system (both
completed and proposed) at various points during the last 70
years. The years chosen were those for which I could find
definitive information or were benchmark years in the development of
the system. Between those dates, short-lived variations to specific
proposals may have been proposed but were not substantially different
enough to warrant inclusion here.
some cases, I found conflicting or incomplete information, so I had to
extrapolate or infer the status of particular segments at certain times
based on earlier and/or subsequent reports. This may result
in some minor inconsistencies.
freeways here replaced existing US and State Highways and initially
carried those route numbers. It wasn't until the early and
mid '60s that Interstate shields began appearing on local
freeways. For consistency and ease of reference, I refer to
the current route designations in the discussions
below. For reference, here is a list of the early highway
designations, including the state highway designation that preceded the
US route number as well as the routing of those routes in 1945
just before the start of the first freeway project.
Most of the routes were adjusted several times as the freeway system
evolved and usurped them.

the construction of San Antonio's freeway system, several existing
sections of US and State highways in the outlying areas were
freeways. The maps on this page show those sections in dark
gray as "pre-freeway" roadways until the time they're
freeway routes were initially served by newly-built
"pre-freeway" roads such as
access roads or FM roads.
For the early segments of I-35 South and Loop 410 that were built first
as access roads but followed within a few years by full freeways, the
initial access road construction and completion is shown on the maps
below as "freeway" because of the short time between those phases. For
Loop 1604 and SH 151, the initial construction of the pre-freeway road
is shown as such on the maps with eventual freeway upgrades shown
from the mid-1940s show the earliest proposal for an "Urban Expressway"
network. That proposal included today's "Downtown Y" sections
I-10 and I-35. Soon, extensions to that core system were
proposed. I-35 North was proposed along what would be its
path. I-35 South was proposed to follow Nogalitos from its
present-day I-35 south to New Laredo Hwy., then south along that
roadway to its present-day intersection with I-35, then south along
present-day I-35 from there (this would have simply been an upgrade to
the existing US 81 route at that time.) I-10 West was proposed to
roughly parallel the rail line from downtown to NW Bexar County. I-10
was proposed to approach the city along the existing US 90 to the
location of today's Loop 410, then follow today's Gembler and
Parkway and join I-35.
section of Loop 410 between NW Military Hwy. and
Harry Wurzbach was actually part of the longer Harry
Highway, which was a single road connecting Fort
Sam Houston to Camp
Bullis. This is why those intersections are angled the way they are to
of the city's first expressway, a 7/10th mile section
of US 87 (also today's I-10) from
Culebra to Fredericksburg at Woodlawn, started in 1946. The road had a
without fanfare on July 8,
November 28, 1949, a ribbon-cutting ceremony on the Colorado
overpass celebrated the official opening of the longer segment from
Woodlawn to today's Frio St. interchange (Comal St. at that time.) From
there, traffic used the existing Laredo/Cameron boulevard along San
Pedro Creek to reach downtown. About a
year later, the expressway was extended along that boulevard from
Martin where it merged into Pecos St. going southbound and from San
northbound. The first section of today's I-35 South, stretching from
Guadalupe at Pecos/San Saba south
to Nogalitos, then opened in
1952, leaving a short gap between the two expressway sections along the
west side of downtown.
proposal for the far northern end of I-10 West had now been
modified to jog further
to the west, meeting Fredericksburg Rd. near Huebner. The
I-35 South proposal had been modified to use today's alignment as far
south as SW Military, then to proceed west on Military to New Laredo
then south from there. A proposal to extend Loop 410 to the west of NW
Military Hwy. would have routed it to near
today's intersection of Callaghan and
I cannot find an official route map for it, I have discovered a couple
of aerial views from this time with a hand-drawn proposed expressway
route through Southtown and the East Side as well as some
artist's renderings for a proposed US 90 expressway
cutting through the middle of the King William
District and a proposed interchange at I-35 near Guadalupe St.
These appear to show the first proposed route for a US 90 expressway.
Coming from the east, the route would have used today's I-10 to
Salado Creek. From there, the route would have followed the Aransas
Ave. corridor to near New Braunfels Ave. where it would have turned
west and followed the Indiana St. corridor. After crossing today's
I-37, it would have turned northwest and crossed Presa and St. Mary's
streets at Sadie St. Continuing northwest, it would have crossed Alamo
St., the King William District, and the San Antonio River between
Sheridan and Beauregard. It then would have continued along Arsenal and
El Paso streets to the aforementioned interchange with I-35. West of
there, I haven't found any definitive route plans, but it probably
would have used the Guadalupe St. and Castroville Rd. corridors to Acme
Road and then the current route of US 90 west of there.
first section of I-35 North, from Martin to Broadway, had been
and was now open. The section of I‑35 from Toepperwein to the county
line-- including an interchange at Pat Booker-- was also complete and the section between Fratt and Toepperwein was just starting construction.
sections of outlying freeways were now under construction. The
first section of access roads Loop 410 running from US 90 to
Bandera was under construction. The alignment for I-35 South between
Military and the future Loop 410 had been adjusted yet again, this time
to its final alignment, and the access roads were now under
routing for either I-10 East or US 90 West inside Loop 410 at this
time, so it seems that the earlier proposal was being reconsidered. The
alignment for I-10 West had moved
again, this time running parallel to Fredericksburg Rd.
for the SE segment of
Loop 410 as well as I-37 was in limbo awaiting a decision on a possible
runway expansion at Brooks AFB. Most of the
alignment for Loop 410 had been finalized and plans for US 90 West were
now underway as well.
public support and federal funding now
covering 90% of
construction costs, expressway planning reached a fevered
this time, San Antonio was generally ahead of other cities with the
Express-News reporting that San Antonio was "outdoing all other Texas
cities who, despite their boasting, have been unable to get an
Expressway into their major business and shopping areas" and officials
were hoping to continue the momentum with the release of an ambitious
freeway plan in 1956.
latest proposal for I-10 West was for the alignment
that would eventually be built. A new proposal for I-10 East appears to
routed it along Rigsby Ave. to WW White Rd., then northeast from there
to today's route. The first proposals for the eventual I-37, US 281
North, and US 90 West were now known and the routing for the
southeastern arc of Loop 410 had been settled.
other freeways were proposed that eventually would be scrapped
including a US 281 South freeway along Roosevelt Ave., the Bandera
Expressway along Culebra Ave. and Bandera Rd., and the first proposal
an "inner bypass" west of downtown along Zarzamora to connect I-10 West
to I-35 South bypassing downtown. This was planned to relieve
congestion that had already manifested on the original sections of I-10.
access roads for I-35
South from SW Military to New Laredo Hwy was complete
now under construction from Nogalitos south to
Division. The elevated "Central Expressway", connecting I-35 North and
and which would carry motorists "in the air through downtown" according
to news reports at the time, was also under construction.

in 1956. Loop 410
access roads from Bandera to Blanco and Culebra to US 90 were under
first proposals for an "Outer Loop" (now Loop 1604) were also made at
this time. The western arc, from I-10 to US 90, was originally
designated Loop 334 before being merged with FM
I only show the overall Loop 1604 proposal during this year. It
remained in the local highway plans from this point forward, but it was
initially built as Farm-to-Market roads. For clarity, from
on, I'll only designate "proposed freeway" sections for Loop
when plans were released to upgrade those sections to a freeway.
"Central Expressway" section of I-35 downtown connecting the three
previously completed expressways north and south of downtown was now
complete and open to traffic.
access roads for the northwestern arc of Loop 410 from US 90 all the
way to Blanco were
now complete. I-35 South had been
completed south of New Laredo Hwy. and from Nogalitos to Division and
was under construction between
Division and SW Military.
North from Broadway to Rittiman and also north of Pat Booker was
now under construction with the section from Fratt to Toepperwein now

sections of freeway were now open to traffic. The western arc
of Loop 410, from Broadway around to I-35 South, was
complete. The earlier sections of Loop 410 between US 90 and NW
Military that were built as access roads had now been upgraded to full
freeway. However, only the western arc of 410 from I-10 West to
I-35 South carried the Interstate 410 shield; the section east of I-10
was marked as State Loop 410 because it was not yet part of the
national Interstate Highway plan. Loop 410
on the Southside between I-35 and Roosevelt was under construction.
I-35 South was now complete; the previous sections of I-35 South that
had been built as access roads had now been upgraded to a full

Broadway to Rittiman and north of Fratt were open while construction on
the remaining section between Rittiman and Fratt was nearing completion.
now complete from Loop 410 north to Fredericksburg and from Woodlawn to
Fresno and under construction from Fresno to Loop 410. The
section of I-10
East from WW White eastward was also under construction.
the first sections of the two-lane FM 1604 were now complete between
I-10 West and US 281.
federal Interstate Highway funding now pouring-in and approval from
city voters of another expressway bond proposal, construction
continuing briskly. In 1962, I-35 had become the
first metropolitan Interstate in Texas to be fully completed. I-10 West
was now complete inside Loop 410 and under construction from Fredericksburg Road to Leon
Springs. I-10 East was complete east of WW White and was under
construction from there to E Houston St.
All of I-35 through Bexar County was now complete, making it the first county in Texas to complete its construction of I-35.
410 on the Southside was open from I-35 east to S Presa, most of the
eastern arc from I-35 North to S WW White
was complete, and the sections between San Pedro and I-35 North had
been upgraded to a full freeway by this time.
first sections of US 90
from I-35 to Cupples and Loop 410 to Pinn, were just starting
sections of the
two-lane FM 1604 were now complete across the Northside from Bandera
Rd. to I-10 East.
now on the
drawing boards including Spur 371 (the "Kelly Access Freeway", now
General Hudnell Dr.) and a revised routing for the previously-proposed
Bandera Expressway that took it through the near West Side and south of
generally along today's Cesar Chavez Blvd. The proposed I-10 bypass was
also back on the drawing boards, slicing a path in the
Zarzamora corridor to connect I-10 and
routing of the North
Expressway (US 281 North), which would soon become quite controversial,
was now being fleshed-out. Two small
connectors were also planned for the
North Expressway: San Pedro Ave. connecting Loop 410 to US 281, and the
St. Mary's Connector, running
parallel to St. Mary's St., connecting US 281 to I-35 just
north of downtown. It would have also featured a downtown
spur in conjunction with elaborate distribution ramps for the other
freeways surrounding downtown.
construction continued to move forward full-steam in preparation for
the 1968 World's Fair ("HemisFair"). By 1967, the bulk of
today's freeway system was complete or under construction. All of Loop
410 was now done, but the section from I-10 West to I-35
North still carried the State Loop 410 designation; it would not see an
Interstate 410 shield until mid-1969.
first section of US
90 West as far as Cupples was open as was the section from Loop 410 to
Pinn. SP 371 was also complete.
was under construction from Florida St. to US 181. All of the
two-lane FM 1604 north of US 90 was now complete as
I-10 West from Leon Springs to Boerne and beyond was complete.
Bandera Expressway proposal was unchanged. The battle over the path for
281 near Hildebrand was raging at this time. The San Pedro and St.
for US 281 appear to have been scrapped by this time.
HemisFair opened, most of the city's freeway system was in
place. All of I-10 and I-35 were open. US 90 West
was complete to Loop 410, and I-37 between Florida St. and SE Military
was done. The section of I-37 between SE
Military to US 181 was under construction as well as the section from Florida
St. to I-35 with part of the section next to the HemisFair area being
temporarily paved and used as a parking lot
for the fair.
over the proposed US 281 North continued on into the new decade and a
fight over another freeway-- the Bandera Expressway-- was gearing-up.
undisputed northern and southern parts of US 281 had begun in 1969, but
was suspended in 1971 when the Conservation Society won a decision to
revoke federal funding. In 1973, Congress allowed the state
city to complete the
freeway without federal funding and work resumed
the original Bandera Expressway route had been scrapped due to city
officials' concerns about its path through the "Model Cities" urban
area on the near West Side. A new proposal for the freeway, now
officially being called the "Northwest Transportation Facility", routed
it along Culebra from I-10 to Loop 1604. In addition, a new route for
the I-10 bypass was
proposed for the near West Side that took it closer to downtown and out
of the Model Cities area.
the controversies, I-37 had been
completed downtown and south to US 181 and work had started from there
south to the Loop 1604 area.
over US 281 North was finally over and the freeway
opened in 1978 and the last section of the original plan, from San
Pedro to Bitters, was
under construction. However, the Bandera Expressway proposal
had been scrapped by this time due to protests over the number of
displacements it would cause. The I-10 bypass was also cancelled;
instead, plans were now underway to double-deck I-10.
last sections of FM 1604
south of the city were now under construction and the road would soon
be renamed Loop 1604. Planning to upgrade the increasingly busy and
dangerous northern arc to a freeway was underway.
the mid '80s, suburban growth was begining to reach the northern
sections of Loop
1604. As a result, an upgrade of the loop to a freeway was
underway from I-10 West to US 281 North and in the area around I-35
North, and was
planned between US 281 and I-35.
Loop 1604 upgrade from I-10 to US 281 was complete as was the new Loop
1604/I-35 North interchange, and work was progressing to upgrade 1604
between US 281 and I-35. Plans to upgrade US 281 from
Bitters to Loop 1604 were announced, and the access roads for SH 151
outside Loop 410 were under construction (not indicated on map.)
most heavily traveled sections of Loop 1604 across the North Side had
now been upgraded to a freeway, ending the days of the "Death Loop",
so-called because of the high number of fatal accidents that had
occurred along it. Plans were now in the works to extend the
western end of the freeway south to Bandera Rd.
upgrade US 281 North between Bitters and Loop 1604 was completed in
record time, and the SH 151 access roads were now complete along its
entire route. Initial proposals for an "East-West Parkway"--
subsequently named Wurzbach Parkway-- to relieve traffic on Loops 410
and 1604 had been announced.
the dawn of the new millennium, short sections of freeway mainlanes had
been added to SH 151 at Potranco, Pinn, and Old Highway 90, and the
freeway mainlanes from Old Highway 90 to Callaghan were under
construction. Proposals to finish the SH 151 freeway were now
on the books.
overpass on Loop 1604 at Kitty Hawk
built in the mid '90s essentially extended that freeway east to FM

the Wurzbach Parkway was open from Wetmore to O'Connor and the segment
from Lockhill-Selma to NW Military Hwy. was nearing completion.
to complete the mainlanes of SH 151 had been completed by
2005. Wurzbach Parkway was done now from Lockhill-Selma to
Blanco Rd. and plans were on the books to finish the remaining
segments. Initial plans to upgrade US 281 to a freeway north
of Loop 1604 to Stone Oak Parkway were announced in the ca.
2000. Plans to build it as a tollway created a storm of
controversy that would delay it for over a decade.
to finally build the missing middle segments of Wurzbach Parkway was
now underway and plans were announced to extend the Loop 1604 freeway
south from Bandera to US 90.
on the first phase to expand Loop 1604 West, from Bandera to SH 151,
