covers Interstate 410 (Loop 410) from the Fratt Interchange (at I-35
north of Walzem) counter-clockwise around the central city to the 410
South Cutoff (at I-35 near Rittiman). From there, Loop 410 continues
north concurrent (multiplexed) with I-35 to the Fratt Interchange, but
because the I-35 mile markers and exit numbers are used along that
stretch, information on that segment can be found on the I-35
49 miles (53 miles including the concurrent section on I-35)

known locally as Loop 410 or just "The Loop", is really a tale of two
freeways. The southern half (south of US 90) demarks the edge
the city and resembles and functions more like a rural Interstate than
an urban freeway. Meanwhile, the northern arc is the
heavily traveled freeway in the region and is home to a major chunk of
the area's suburban office space and several major shopping
centers. The Loop also provides access to San Antonio
International Airport, the South Texas Medical Center, the Southwest
Research Institute, the Westover Hills area and Sea World of Texas, the
National Security Agency campus, Ft. Sam Houston, Lackland AFB, Brooks
City-Base, Stinson Municipal Airport, the San Antonio Missions Trail
National Park, Palo Alto College, Texas A&M University - San
Antonio, the Toyota assembly plant and adjacent facilities, and the
cities of Castle Hills, Balcones Heights, Leon Valley, Kirby, and
Land along the northern arc is heavily developed. Office
shopping malls, hotels, and other commercial developments dominate the
landscape, interspersed with dense residential areas. South
90, development is much more dispersed with large tracts of vacant
land, although this area has been seeing new growth in recent years.

410 intersects with I-35 North at two places: Loop 410 North intersects
I-35 north of Walzem Rd. at the Fratt Interchange, and Loop 410 East
intersects I-35 south of Rittiman Rd. at the 410 South Cutoff. Both
highways run concurrent (multiplexed) between these interchanges.

heavy along northern arc (US 90 West to I-35 North). The
section has been San Antonio's busiest or second busiest freeway over
the past few years, exceeding 200,000 vehicles per day between I-10 and
US 281. Much of the chronic congestion along this stretch has
been eased with the completion of several expansion and interchange
projects over the past decade. However, that construction has
temporarily reduced overall traffic along those sections, although
traffic counts in the completed areas have started to recover.
southern half carries generally moderate traffic. However,
fastest growing areas for traffic on 410 are all south of US 90,
especially in the vicinity of the I-37 interchange.

of today's I-410 route was originally part of Loop 13 (the southern
half of which still exists today as WW White and Military Dr on the
south and east sides.) The section from the Fratt Interchange
south to WW White was authorized in 1941, and the section from the
Fratt Interchange west to NW Military was in place as early as
1950. In 1951, the first plan to start extending the loop
westward routed it from NW Military to the intersection of
Fredericksburg and Callaghan. By 1957, however, the
route from NW Military around the west side of the city to I-35 South
was proposed, as was the eastern arc from Rittiman south to Sulphur
Springs. That western section, along with the southern
from I-35 to Roosevelt, was completed by 1964. The remainder
the loop was complete by 1967, including an upgrade of the original
highway from Austin Hwy. to NW Military to freeway standards.
That section, however, was signed as State Loop 410 until August 1969,
while the rest of the new freeway was designated I-410 as it was built.
Ingram to I-35 North was expanded to six lanes in the late '70s and
early '80s. The Fratt interchange was rebuilt in a rather
spectacular project between 1980 and 1983. The section from Ingram to
Valley Hi was expanded to six lanes ca. 1987. An extra lane
added westbound from I-10 West to Babcock in 1996. The
from West Ave. to Cherry Ridge was expanded to 10 lanes (eight lanes
actually marked initially) in 1997. TransGuide coverage was
from Ingram Rd. to I-35 North in 1999. The section between
McCullough and US 281 was widened and prepared for the planned 218/410
interchange in 2000 and 2001. The section from I-10 to
was widened to 10 lanes in 2003, and the section from West Ave. to
Blanco widened to 10 lane (eight lanes initially marked) in
The section from Blanco to McCullough was widened to 10 lanes in 2008,
and the section from Jones-Maltsberger to Broadway was widened to 10
lanes in 2009. The first ramp in the 281/410 interchange
to traffic on June 18th, 2007 and the final ramps were opened to
traffic on June 9th, 2008. Work on the I-10 West interchange,
including widening the Loop to eight lanes, was completed in early
2009. The elevated Bandera connectors opened in May 2009 and
to widen the section from Callaghan to Ingram to eight lanes was
completed shortly thereafter. The section from Culebra to
was completed in late 2009 and the final section, from Nacogdoches to
Austin Hwy, was completed in late 2010.
