This summer the Texas Department of Transportation will begin a four-year construction project on SH 121 interchanges at I-635 and FM 2499.

A TxDOT press release said the $370 million project between Grapevine and Flower Mound will have crews working along 3 miles of SH 121 to improve mobility and safety and to relieve the bottleneck between I-635 and Farm to Market Road 2499.

The project is part of an overall $3.8 billion congestion relief initiative called Texas Clear Lanes, which was created to address traffic congestion in metro areas across the state.

SH 121 will be widened and rebuilt north of the Dallas/Fort Worth International Airport to accommodate new interchanges for SH 121 at I-635 and FM 2499. The Bass Pro Drive bridge will also be widened and reconstructed along the frontage roads.

"Projects like the SH 121 project will improve drive times, reduce costs, and improve quality of life for our Texas drivers,” Chairman J. Bruce Bugg Jr. said in the press release. “Texas’ legislative leadership and TxDOT’s Transportation Commission are committed to reducing congestion. I am grateful to Senator Jane Nelson and Representative Giovanni Capriglione for their support in making these funds available."

The press release said the SH 121 interchanges at I-635 and FM 2499 were included in the initial DFW Connector project, but funds were not available at that time to deliver the entire scope. With the Texas Clear Lanes congestion relief funding, this portion of the original project can be delivered.

The project is estimated for completion in 2022.
