Project - TEXAS: Express Toll Lanes on I-35 in San Antonio

The San Antonio district of the Texas Department of Transportation (TxDOT) evaluated managed lane options for a 15-mile section of the Northeast Corridor (I-35). Public involvement was key in developing the I-35 project. Pre-project studies provided some guidance in developing managed lanes, including incorporation of value pricing. Although TxDOT is an existing partner with value pricing projects in Dallas and Houston, this was San Antonio's first VPPP grant.

The project evaluated potential operating strategies, including value pricing, which could be used as tools to manage travel demand on I-35. The team evaluated alternative pricing scenarios that could be utilized to allow certain user groups into the managed lanes at different stages over the facility's life. The I-35 Managed Lanes study was expected to show congestion-reducing benefits on a 15-mile stretch of the Northeast Corridor.

Project Completed

The road will probably be tolled in some form once it is completed and responsibility for the project has been turned over to the Regional Mobility Authority, the local tolling agency. Selection of an alternative is not anticipated for at least 5 years because the political climate in the area is unfavorable toward tolling and the project involves a large portion of elevated roadway adding considerable expense.
