I-45 Expansion

The Texas Department of Transportation (TxDOT), is proposing to reconstruct and widen IH 45 from FM 1764 to north of the Galveston Causeway Bridge in Galveston County, Texas. This website was created as a resource for citizens and business owners in La Marque. This project is being executed by the State of Texas, not the City of La Marque. City leadership is working closely with TxDOT, however, and will continue to provide updates as soon as they become available.

If you are an impacted property owner, the TxDOT Right of Way Project Delivery – Houston District team will contact you.

Traffic update from TxDOT: closure at Texas City Wye June 2, 2018

There is an upcoming closure that will be taking place on IH-45 Northbound on June 2, 2018, weather permitting. There is possibility of needing a second weekend if work is not completed. City of La Marque will update with any changes as soon as we are notified. Please see details below.

Two alternating northbound main lanes on IH-45 at the Texas City Wye will be closed June 2, 2018 from 2 AM to 3 PM for pavement repairs.
