The Highway is Expanding &
Seabrook is getting a Facelift

 

The SH 146 Expansion Project will expand 146 in a fashion similar to other parts of SH 146 which runs north of Seabrook through La Porte. Beginning at Red Bluff Road the highway will be expanded south through Seabrook. A new expressway bridge will be built west of and parallel to the Seabrook-Kemah Channel Bridge. The current bridge will remain and serve as a frontage road for motorists.

Specifically, the project will consist of the following:

  • Widen and restructure the existing facility from a six-lane roadway to a 12-lane freeway.

  • Add grade separations at major intersections.

  • Add access roads in selected location.

  • Add express lanes over Clear Creek.

This site is your information source for project and construction updates. While the website is maintained by the City of Seabrook, the expansion project is managed by TxDOT and their partners and contractors.

 

What to expect and when…

 

Many may wonder “if” and “when” actual construction will begin, so let us break it down for you. The current schedule is as follows:

  • Right-of-Way Acquisition and Demolition is Ongoing
    TxDOT began acquiring properties in January 2016 and as properties are acquired and vacated TxDOT will schedule demolitions. This is a long process but is nearing the end.

  • Utility Relocations is Ongoing
    A variety of utilities and pipelines must be relocated as the project progresses. Utility relocation began in November 2018.

  • Construction Phase 1 - Slated to begin Spring 2019
    This phase will widen the northbound side of the existing bridge and will construct the northbound frontage road in Seabrook. The phase is expected to take between 12 to 18 months weather permitting.

  • Construction Phase 2 - Slated to begin upon completion of Phase 1
    This phase will widen the southbound side of the existing bridge, construction of the southbound frontage roads in both Seabrook and Kemah and construction of the new express bridge. Tentatively, Phase 2 will take at least two years to complete, weather permitting. 

*Phase 1 and 2 will be expanded upon further once construction has begun. Please check our Recent Updates page for the most current information.

 

TxDOT & Partners

 

The SH 146 Expansion is a project overseen and managed by the Texas Department of Transportation; the Seabrook portion of the expansion is managed by the Houston Division. TxDOT let the project in May 2018 and later awarded engineering consultation services to RS&H and gave the construction contract to Webber. Both organizations have partnered with TxDOT on several projects over the years.
