The Texas Department of Transportation announced the execution of an agreement to begin developing a Grand Parkway extension from League City to Alvin.

The extension project is known as Segment B and is proposed to stretch from I-45 South to Hwy. 288. The map of the proposed project provided by TxDOT is preliminary and is subject to change.

A statement from TxDOT reads that the department entered into project agreements with Galveston and Brazoria Counties allowing TxDOT to deliver the initial portion of Segment B, which is proposed to run from I-45 in League City to FM 2403 in Alvin.

"TxDOT and Brazoria County will assess the delivery timeframe of the remaining portion of Segment B from FM 2403 to SH 288 as a separate and future project," the statement reads.

According to TxDOT, a contract for construction is expected to be awarded in 2025, and the project is estimated to be completed by 2030. An environmental review of the project was previously approved in November 2016.

State Rep. Ed Thompson, R-Pearland, said in a release that the project will be a large benefit for Brazoria County and the region.

"As our community rapidly expands, it's important to invest in infrastructure that promotes interconnectivity and economic growth for our cities, schools, and businesses,” Thompson said in the release.

The release states the expansion will allow for increased commercial traffic and improved storm evacuation capacity while complimenting the growth of the area.
