If you have plans in Galveston this weekend, you might want to rethink them. 

Starting Friday night, crews with the Texas Department of Transportation will close the southbound lanes of I-45 between FM 517 in Dickinson and FM 2004 near Texas City, which is a little over four miles. Drivers will be diverted to the southbound feeder road for the duration of the closure. Workers plan to open the lanes back up early Monday. 

The closure will start at 9 p.m. Friday night. The lanes could open up sooner than anticipated if workers finish up ahead of schedule. 

The work is part of a massive widening project for I-45 in Galveston County that carries nearly a $1 billion price tag. Plans include widening the freeway to 10 main lanes, according to the transportation department. 

This stretch from FM 517 to FM 2004 alone costs $229 million, according to TxDOT's project tracker. TxDOT did not immediately respond to a request for details on this weekend's work. This four-mile section will be complete in September, while the entirety of the widening project in Galveston County is expected to be finished in 2025.

While southbound drivers will be routed to the frontage road, they can also take a longer route around the closure south on FM 646 to FM 1764, then back east toward I-45. Drivers bound for Galveston can also head further south on FM 646 to Texas Highway 6 near Santa Fe before turning left toward Galveston. 

The northbound lanes will not be affected.
