SH 146 Expansion


The expansion of the Highway 146 is greatly needed to alleviate daily traffic congestion and will also allow safe passage for motorists during hurricane evacuations. SH 146 is an official hurricane evacuation corridor.

Project Overview


In summary, the TxDOT project will expand the highway in a fashion similar to other parts of SH 146 that run through the city of La Porte. Beginning at Red Bluff Road, the highway will be expanded south through Kemah. A new expressway bridge will be built west of and parallel to the Kemah-Seabrook 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 to a six- to 12-lane freeway
  • Add grade separations at major intersections in Seabrook
  • Add access roads in selected locations
  • Add elevated express lanes over Clear Creek and through Kemah

More details concerning the physical logistics of the project will be released closer to the construction phase. At this time, the construction phase of the project is not expected to break ground until 2018.
