I-45 South Walker County Project

The purpose of this project is to enhance freight mobility and address congestion along the I-45 corridor. The project limits are from 0.2 miles south of the Montgomery County Line to 0.3 miles north of SH 19 with a length of 12.6 miles. No additional right of way is required. The project is not yet funded but is estimated for letting in December 2015. Construction is anticipated to begin in early 2016 and expected to last three years with an estimated cost of $240 million.

Background

The freeway within the project limits was constructed in the early 1960s
Passenger and truck traffic has greatly increased during the 50-year lifespan of the facility
I-45 serves as the primary hurricane and disaster evacuation route for metro Houston and Galveston
