I-35 and Loop 337

Project ID (CSJ):  0016-05-107

Overview:

Recent business developments and area growth near the intersection of Loop 337 and I-35 have increased traffic congestion, exceeding the highway's current capacity. Local leadership has partnered with TxDOT to develop a solution that will address the growing traffic and reduce the safety risks associated with the congestion.

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.
End Result
This project will address congestion while improving safety at this intersction by:
  • Adding lanes to Loop 337 between I-35 and Altgelt Road
  • Adding lanes to the Loop 337 overpass bridge at I-35
  • Improve turn-lanes along the I-35 access roads at Loop 337
Funding
  • Construction Cost Estimate:
    $3.2 million
Schedule
  • Construction began spring 2014 and is expected to be complete late 2014
