Several lane closures are set to take place this weekend around the north Grapevine area. NorthGate Constructors will conduct two major operations from Aug. 9-Aug. 12 for the I-635/SH 121 interchange project. The first operation will switch traffic onto the new eastbound Bass Pro Drive bridge over SH 121. The second will demolish the former westbound Bass Pro Drive bridge over SH 121.

The $370 million Texas Department of Transportation project includes rebuilding and widening SH 121 north of the Dallas-Fort Worth International Airport to accommodate new interchanges for SH 121 at I-635 and FM 2499. The Bass Pro bridge in Grapevine will also be widened to six lanes and reconstructed along with the frontage roads. The project is expected to be completed in 2022.

Here are the closures drivers should be aware of as they travel through this area:
