Project ID (CSJ): 0017-10-261
Business developments and area growth in San Antonio along I-35
have increased traffic congestion, exceeding the highway's current capacity.
The City of San Antonio passed along a $20 million dollar grant from the U.S.
Department of Defense to help address the needs along one of the most congested
roadways in Texas. The City's partnership with TxDOT reflects the understanding
of all regional transportation partners that I-35 is vital to the Texas economy
and our quality of life.
Need & Purpose
- Need: Increased truck traffic along the I-35 corridor
coupled with regional population growth in Texas has created
travel demand that exceeds its current capacity. The existing
I-35 facility through Central Texas is an essential element of
the local and regional transportation system.
- Purpose: The purpose of the project is to meet local and regional travel demands by increasing capacity; upgrading the transportation infrastructure to meet current FHWA and TxDOT
design standards for interstates, bridges, and frontage roads;
thereby improving the safety of travelers along I-35.
- Alignment of certain exit and entrance ramps increases
This project will address congestion while improving safety at this
- Expanding the expressway from 6 - 8 main lanes
- Reconfiguring specific exit and entrance ramps
- Providing auxiliary lanes between entrance and exit ramps to
allow acceleration and deceleration
- Converting the southbound I-35 exit to southbound I-410 from
a left-side exit to a right-side exit
- Construction Cost Estimate:
- Construction began fall 2013 and is expected to be completed
