I-45(S) to SH 288
Segment B

Segment B is a proposed 28-mile, four-lane, controlled access toll road with intermittent frontage roads from I-45(S) (the Gulf Freeway) in League City, towards SH 35 in Alvin and on to SH 288 (the South Freeway) near Rosharon through Galveston and Brazoria Counties.

For Segment B, the alternative alignments were developed within the project area to fulfill the need and purpose of the project, to minimize potential environmental impacts, and to respond to public/landowner and resource agency comments. Identification of the Recommended Alternative Alignment was based on public and resource agency input, and analysis and comparison of the potential effects on the physical, biological, and human environments of each alternative alignment.

The Recommend Alternative Alignment is shown in the maps below. Click on the individual squares to view detailed maps of Segment B.
