Starting Friday, April 20 at 9 p.m., TxDOT contractors will be closing the northbound IH-45 exit ramp #23 (League City 518 Exit), until further notice. This construction is part of the IH-45 widening project and will take months to complete.
In addition, there will be a rolling freeway closure of all main lanes and frontage roads on IH-45 between FM 518 and NASA 1 on Sunday, April 22 for approximately one hour from 6 to 7 a.m. Freeway traffic will be at a complete stop on both directions for at least 15 minutes or more. We suggest taking alternate routes if possible, as traffic delays are expected during these closures.
