The Texas Department of Transportation (TxDOT) proposes to expand Loop 1604 from FM 78 to IH 10 in Bexar County, Texas. To accommodate transitions, the construction limits on Loop 1604 would begin approximately 1,500 feet west of FM 78 and end approximately 2,700 feet south of IH 10; approximately 6 miles. The project construction limits would include approximately 2,500 feet along FM 78, 600 feet along Rocket Lane and 2,000 feet along Lower Seguin Road. The proposed project would require approximately 51 acres of new right of way (ROW).
The project would expand Loop 1604 from a four-lane divided highway to a four-lane expressway between FM 78 and IH 10. The controlled access main lanes would consist of two 12-foot wide general purpose lanes with variable shoulders. The frontage roads would typically include two lanes each way except at the Martinez Dam detention pool where they would transition to one lane and at the approaches to major intersections where turn lanes would be included. The lanes would typically consist of one 12-foot wide inside lane and a 15-foot wide outside lane and variable shoulders.
Ramps would be constructed between the controlled access lanes and frontage roads. Auxiliary lanes would be constructed between entrance and exit ramps.
The project would construct several bridges, including an elevated U-turn bridge between FM 78 and Hanover Pass, and overpasses at the U-turn, Rocket Lane, Lower Seguin Road, Graytown Road, and Binz-Engelman Road. The bridges over Salitrillo Creek and the Martinez Creek Dam impoundment would be widened to carry one lane frontage roads across the floodplain. The corridor would provide 18.5 feet vertical clearance for freight traffic.
Lower Seguin Road would be realigned to intersect at right angles with Loop 1604. Six-foot sidewalks would be constructed along the frontage roads between FM 78 and the north end of Salitrillo Creek, and between the south end of Salitrillo Creek and I-10 E. Wide outside lanes and/or shoulders would accommodate bicycles the entire corridor. Storm drainage would be conveyed primarily by roadside ditches and underground storm sewer system where space is limited. Culverts would be added or modified to accommodate cross drainage. Illumination and traffic signals, signs and pavement markings would be added, removed or modified as necessary.
