Antonio Area Freeway System
Loop 1604 (Charles W.
last updated November
covers the freeway segment of Loop 1604 across North San Antonio from
FM 78 in Converse to Braun Rd. The remainder of the 95 mile
is non-freeway, most of which is a two-lane rural road.

it was built
in the 1960s, nobody ever believed that Loop 1604 North would become
the busy beltline that it is today. While the southern half
remains in its original configuration as a two lane rural state
highway, most of the northern arc has been expanded to a four lane
freeway. Loop 1604 forms the outer of San Antonio's two
and the freeway portion serves Randolph AFB, Rolling Oaks Mall, the
Stone Oak development, Camp Bullis, the University of Texas at San
Antonio's (UTSA) main campus, Six Flags Fiesta Texas, the Shops at La
Cantera and the La Cantera development, The Rim development, Valero
campus, and the suburbs of Converse, Universal City, Live Oak,
Hollywood Park, Shavano Park, and Helotes. The corridor runs
through increasingly dense suburban residential areas with some
moderate to heavy commercial development, especially near I-35, US 281,
I-10, and Bandera Rd.

is indeed Loop 1604; FM 1604 is in North Texas. (See the History section

experienced ridiculously blistering traffic growth during the 1990s
with average AADT counts up well over 300% along nearly the entire
route, and up nearly 800% near Bandera Rd. However, that
moderated a bit during the past decade. Still, the section west
was up nearly 100% overall. Generally, volume is moderate to
heavy along entire route. The section between I-10 and US 281
exceeds 100,000 vehicles per day, up from a paltry 25,000 in
1990. Recurring congestion occurs during morning
evening peak periods between Bandera Rd. and US 281.

the east end, work
is underway to widen the loop to a four lane divided highway from Lower
to I-10 East.
TxDOT and the
Alamo Regional Mobility Authority released plans in June 2007 for a
$1.8 billion mega-project to upgrade and expand Loop 1604 across
northern San Antonio from Military Dr. West around to I-10
This project would add tolled expressway lanes where there are
no expressway lanes (i.e. south of Braun Rd. and south of FM 78) and
along the existing expressway would add new tolled express "managed"
lanes in the median between the existing free expressway lanes, which
will remain free. Additionally, it would build major
at SH 151, I-10W, US 281N, I-35N, and I-10E, as well as modifications
and improvements on those intersecting roads. An
impact study on the entire corridor is currently underway and is
expected to be completed in 2012.
2009, Congress approved a national economic "stimulus" plan
that poured additional federal money into road construction
The Metropolitan Planning Organization (MPO) approved allocating San
Antonio's share of transportation stimulus funding to be used as
matching funds to leverage state funding for first half of a 281/1604
interchange. This project is building all four of the ramps
connecting to 281 south of 1604, i.e. northbound 281 to both directions
of 1604, and both directions of 1604 to southbound 281. The
of the federal funds allowed the ramps to be toll-free. The
Texas Transportation Commission (TTC) approved the funding request on
March 5th, 2009. Construction began in early 2011 is expected to
be complete in early 2013. It
determined that ramps connecting to 281 north of 1604 could not be
built until lingering issues stemming from the lawsuits and associated
environmental studies for 281 north of 1604 are resolved.
However, funding has already been set aside for those ramps so
that construction can begin as soon as the legal and environmental
issues are resolved. For more information on
the 281/1604 interchange, click
13th, 2009, it was reported that opponents to the 281 North toll
were considering a legal challenge to the 281/1604 interchange on the
grounds that it should be subject to a new environmental review as part
of the entire Loop 1604 and US 281 studies. However, as of
end of 2009, no lawsuits had been filed. Environmentalists
hinted in late April 2010 that they might sue to stop the interchange
unless sufficient measures were taken to protect endangered species in
the vicinity. Despite reported negotiations, a lawsuit was
subsequently filed in August 2010. In early February 2011,
federal judge in the case indicated that he would not be issuing an
injunction against the project prior to hearing the case, which as of
late 2012 still had not occurred. Work on the project
subsequently began in late February. In April 2011, the
judge officially denied an injunction against the project.
lawsuit remains pending although its outcome is now essentially moot.
In May 2012,
local officials identified funding to construct new toll-free
expressway lanes from Bandera Rd. south to Wiseman Blvd. It is
hoped that construction can begin sometime in 2014 once the ongoing
environmental study of the corridor is complete. For more

assembled from a number of Farm-to-Market and State Loop roads in the
early '60s and holds the distinction as the only four-digit road in
Texas that is not a Farm-to-Market road. One of the FM roads
was included in the eventual loop was FM 1604, and segments of other
roads added to the loop were renumbered as FM 1604. However,
the loop was done and state officials were ready to change the
designation to a Loop, they found that the 1604 number had become
familiar to area residents. So in 1977 they simply changed
route designation to Loop 1604. (FM 1604 has since been
and is in use in Irene, Texas, east of Hillsboro.)
usurped all or parts of FM 1518, FM 1604, FM 1627, and FM
FM 1518 ran from Somerset east to Elmendorf, then north to near US 87
and then on to Schertz. FM 1627 was a short road connecting
to Pat Booker, and FM 2173 connected Somerset to Macdona.
was also a proposed Loop 334, which would've run along today's 1604
routing from I-10 West to Macdona; this route was instead eventually
built as part of the 1604 project.
'50s, work began on the first segment of FM 1604 from I-10 to US 281
and was completed around 1958. By 1964, it had been extended
Bandera Rd. on the west and to I-10 East. It reached Macdonna
1974. FM 2173 and 1518 were upgraded and redesignated as FM
in the mid '70s, and the missing section, between I-10 East and FM 1518
was built in the late '70s.
interchanges at I-10 and I-35 were completed around 1986.
1987, the section between US 281 and I-10 was upgraded to a four lane
freeway. The section between US 281 and I-35 was upgraded to
freeway in two phases in the late '80s. The segment from I-10
Babcock was upgraded in the early '90s as was the section from I-35 to
FM 78. The section from Babcock to Braun Rd. was completed in
1996. The section from Braun Rd. to near Culebra was upgraded
a divided highway in 1999, and the overpass at Culebra opened in mid
2004. TransGuide coverage was added to the section between
Babcock and Tradesman in 1999. The previously missing access
roads between NW Military and Bitters were added during the Summer of
2002. TransGuide coverage was extended to the section from
to Bandera Rd. in April 2003. Work to upgrade the section
151 south to US 90 from a two lane rural road to a four lane divided
highway was completed in 2007 and work to widen the section from FM 78
to Lower Seguin Rd. to a divided highway was complete in September
The first ramps
in the 281/1604 interchange opened on November 8, 2012.
