TxDOT Proposes Widening of I-45

TxDOT To Hold Open House to Propose Widening I-45 from the Montgomery County Line to SH 19 in Huntsville, Walker County.


The purpose of this project is to improve safety and mobility along this portion of I-45. The project limits are from the Walker/Montgomery County Line to the south end of Huntsville, with a length of 12.4 miles.

Proposed improvements include:

  • Replace existing mainlane pavement with new pavement
  • Widen to six travel lanes (three north and three south) with a center concrete traffic barrier instead of a grass median
  • Extend and replace drainage
  • Replace all existing bridges
  • Add a new direct connection from northbound I-45 to northbound SH 19
  • Reconstruct ramps to current standards
  • Reconstruct frontage roads and crossroads adjacent to new ramps and interchanges

No additional right of way is required and construction is estimated to begin in 2016. Please see the I-45 South Walker County project page for more information.
