I-45’s southbound lanes from FM 518 to Hwy. 96 will be completely closed from 9 p.m. today until 5 a.m. Monday, according to a Texas Department of Transportation press release. TxDOT will be restriping that section of the road as part of its I-45 widening project in the League City area, according to the release. Southbound I-45 motorists will be detoured to the FM 518 exit to South Gulf Freeway and continue through an intersection to re-enter the main I-45 southbound lanes after Hwy. 96, according to the release. Motorists will experience delays. Police officers will be on-site to direct traffic, according to the release. Additionally the northbound FM 646 exit ramp and outside I-45 main lane will be closed Saturday until Monday so workers can reconfigure the temporary ramps between FM 517 and FM 646, according a League City press release.
