SH 288 Toll Lanes in Brazoria County: CMT’s Quality Testing Success

The project adds four managed lanes within the highway’s grassy median, easing congestion from CR 60 to the Harris County line. CMT provided comprehensive construction-materials testing to keep every element compliant with TxDOT standards.

Why This Project Matters

  • Less traffic: Extra lanes cut daily delays for commuters.
  • Better connections: Faster travel between Brazoria and Harris Counties.
  • Economic boost: Reliable freight routes attract new business.
