A major project at I-45 and FM 518 will begin Sept. 16, affecting traffic until the end of the year.

According to a League City news release, the Texas Department of Transportation's project will add double left- and right-turn lanes to east- and westbound FM 518 at I-45.

Additionally, TxDOT will increase the number of lanes on the north- and southbound I-45 frontage roads from four to six, including double left- and right-turn lanes and dedicated U-turn lanes.

When complete, FM 518 will have 10 total lanes running under the I-45 overpass, including two dedicated left-turn lanes in each direction and three through lanes in each direction, the release reads.

The work will provide "much-needed traffic relief" at the intersection, but the construction will cause a temporary increase in traffic congestion in the area, according to the release.


Work will start on the north side of FM 518 between Lafayette Lane and North Wesley Drive. Traffic lanes on this section of FM 518 will transition to one lane in each direction with additional lanes open at the I-45 intersection, the release reads.

To help keep traffic flowing at the intersection of FM 518 and Lafayette Lane and Hobbs Road, left turns will be prohibited in all directions. The traffic signal at the intersection will be offline during this part of construction.

Businesses will remain open and accessible during construction, and League City will provide updates during the project.

The project was originally scheduled to begin Sept. 9 but will now begin Sept. 16.
