Project Overview

The initial $1 billion DFW Connector project was simultaneously designed and built along 8.4 miles of SH 114 and SH 121 in Grapevine, Southlake and Irving. It doubled the size of the existing highway system around the north entrance of DFW International Airport. The project featured a combination of new mainlanes, frontage road lanes and TEXpress Lanes. The initial project completed in March 2014.

Funding constraints required some original DFW Connector segments to be deferred. However, since 2013, TxDOT has been able to identify funding for FM 2499, new SH 121/360 ramps, the SH 121/360 interchange, and SH 121 interchanges at I-635 and FM 2499. FM 2499 work included rebuilding the mainlanes from SH 121 to Denton Creek. The SH 121/360 ramps project constructed new on-ramps from the southbound SH 121 frontage road (William D. Tate Avenue) to SH 121 and SH 360.

Rone provided QC testing services for the initial project and is currently providing QC testing services on the SH121/360 interchange. Rone has also been awarded a contract by NorthGate Constructors to provide QC testing services for the SH 121 interchanges at I-635 and FM 2499, which began in 2018.
