The Texas Department of Transportation (TxDOT) and the Federal Highway Administration (FHWA) propose improvements to Interstate Highway 35 (I-35) in South Central Texas from I-410 South in San Antonio to Farm-to-Market (FM) 1103 in Schertz. The proposed project would add capacity in the form of elevated managed lanes. In addition, proposed direct connectors would link the managed lanes to the existing I-410 South, I-410 West, and Loop 1604 facilities. The proposed project, generally referred to as the I-35 Northeast San Antonio Expansion Project, is located in Bexar, Guadalupe, and Comal Counties. Cities and towns within the study area include San Antonio, Windcrest, Live Oak, Universal City, Selma, Schertz, Kirby, and Cibolo. The construction limits of the project account for transitions into the existing roadways and extend approximately 2.8 miles south of the project begin at I-410 South to just south of Copeland Drive, and extend approximately 1.3 miles north of the project end at FM 1103. In support of efforts to reduce project construction costs while maintaining an acceptable return on the investment, SLG studied alternative project scenarios by looking at revised direct connector alignments and designing cross-over bridges to allow potential elimination of portions of the managed lanes. Also, assisted in development of revised quantities and cost estimates for the project.
