The purpose of this 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 being studied by TxDOT. Segment 2A is a proposed 4.4 mile long project in the city limits of Huntsville from 0.3 miles north of SH 19 to 0.9 miles north of SH 30. 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.   

Background

  • The existing I-45 facility consists of a four-lane divided controlled access freeway. There are two travel lanes in each direction, bounded by 10 foot outside and 6 foot inside shoulders. Two-lane one-way frontage roads are positioned on the outside of the main lanes.
  • 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.

Segment 2A

Segment 2A is a proposed 4.4 mile long project in the city limits of Huntsville from 0.3 miles north of SH 19 to 0.9 miles north of SH 30.  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 includes adding collector-distributor roads, which is a road that parallels and connects the main travel lanes and frontage roads.

The proposed Segment 2A project would require additional right of way of approximately 11.5 acres and would displace four commercial structures. This project is funded at $200 million for construction and estimated for letting in Summer 2021 and construction in Fall 2021.

Segment 2B

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.
