Project Timeline


In late Aug. 2016, NorthGate Constructors began work on improvements to the SH 121/360 interchange in Tarrant County. The SH 121/360 Interchange improvements were included in the original $1.6 billion DFW Connector project, but funds were not available at that time to deliver the entire scope. When congestion funding became available for these improvements in Feb. 2016, TxDOT and NorthGate Constructors negotiated a plan to rebuild this portion of the original project.

The new SH 121/360 Interchange will minimize weaving and reduce congestion on both SH 121 and SH 360 when complete. From northbound SH 360, there will be two new ramps: one to SH 121 and one to SH 114. From northbound SH 121, there will be a new ramp to westbound SH 114 and a reconfigured exit to William D. Tate Avenue.

From the existing eastbound SH 114 to southbound SH 121/360 bridge, NorthGate Constructors will add a new ramp to southbound SH 121 and reconfigure the ramp to southbound SH 360. From southbound SH 121, there will be a new ramp to SH 360. Click here for our fact sheet.

Below is a summary of work that will take place in late summer/early fall 2017:

  • Drainage and dirt work continues on the northbound SH 121/360 frontage road. This area will become the future northbound SH 121 and northbound SH 360 ramps to westbound SH 114.
  • Paving and wall work is ongoing in the SH 121 median.
  • Construction has started on all four new bridges in the area:
    • All bridge beams, or girders, have been placed on the project. Crews are now working on the bridge deck for the new eastbound SH 114 off-ramp to southbound SH 121 and northbound SH 121 off-ramp to westbound SH 114. Crews are tentatively set to open these two new bridges in late summer/early fall.
    • Bridge demolition for the old northbound SH 360 bridge to northbound SH 121 will take place later this summer.
