Interstate 45 (I-45) Widening Project by TxDOT in the City Limits
The purpose of the project is to enhance freight mobility and address congestion along the I-45 corridor. There are two proposed segments within the Central Walker County Project that are currently under design by TxDOT. These segments are Segment 2A and Segment 2B. More information is available on the TxDOT Project Page.
Segment 2A is a proposed 4.4-mile long project entirely within the city limits of Huntsville, from 0.3 miles north of State Highway 19 to 0.9 miles north of State Highway 30. TxDOT has scheduled to let the project for construction in September 2020. Construction duration is not available at this time, but initial estimates are that it will take 3 to 4 years to complete this segment of the widening project.

Segment 2B is a proposed 4.7 mile long project in the city limits of Huntsville from SH 30 To 0.7 miles south of FM 1696. It would widen I-45 from four to six lanes and would include reconstruction and realignment of the main lanes and ramps; improving drainage structures and bridges; and improvements to frontage roads, crossroads adjacent to new ramps, and interchanges. The project also relocates the interchanges of SH 75 to near San Jacinto Street (west of I-45) and Moffett Springs Road (east of I-45). Segment 2B does not include collector-distributor roads.
While this project is not yet funded, once approved the project is estimated for letting in Summer 2023 and construction in Fall 2023.
