Future Transportation Corridor
The Future Transportation Corridor is an area for additional capacity on I-35 for 60 miles through Williamson, Travis and Hays counties that would provide the single largest mobility gain for I-35.
- Extends from SH 130 (north of Georgetown) to Posey Road (south of San Marcos)
- Benefits include increased capacity, improved mobility and increased reliability
A Planning and Environmental Linkages Study (PEL) was conducted to help determine how this lane would be used in Travis County. There were nine potential lane type alternatives/mode choices considered for the Future Transportation Corridor:
- General purpose lanes
- High occupancy vehicle lanes with transit
- Express lanes with transit
- Express lanes with enhanced transit access
- Through-traffic only lanes
- Transit-only lanes
- Freight-only lanes
- No build
The PEL Study recommended that two express lane alternatives be further evaluated in future National Environmental Policy Act (NEPA) studies: an express lane with transit and an express lane with enhanced transit access.
The PEL study also determined the purpose and need and three logical segments of independent utility (three stand-alone projects) for the Future Transportation Corridor in Travis County. The three stand-alone projects were determined to be:
- SH 45N to US 183*
- US 183 to Riverside Drive
- Riverside Drive to SH 45SE
*After further traffic analysis, the northern limit for this project was extended from SH 45N to RM 1431.
The lane type alternative/mode choice has not yet been determined for the Future Transportation Corridor in Hays and Williamson counties.
