New off-ramp to northbound SH 121 opening and 3 more transportation projects to know in Grapevine, Colleyville, Southlake


Work continues on the four projects listed below. Here are recent updates and what drivers need to keep in mind as they travel.

1. SH 121/I-635 interchange widening

The new northbound SH 360 off-ramp to northbound SH 121 has officially opened. This was the first new bridge to open as part of the project. Weekend closures were carried out for crews to demolish the old bridge along the SH 121/I-635 interchange corridor. The northbound SH 26 off-ramp to SH 121 has been removed, and the new northbound SH 26 off-ramp bridge to SH 121 has opened in its place. Crews are working to take down the eastbound Bass Pro Drive bridge and will take down the I-635 on-ramp at Bass Pro in August. Work is expected to reach the halfway point by the end of the year.

3. North White Chapel Boulevard widening, Phase 2

Crews have shifted traffic to close the west side of the intersection at Highland Street and North White Chapel Boulevard. The closure will allow crews to work on the west side of the roundabout.

Eastbound and westbound traffic have been eliminated until the roundabout opens. The work on the roundabout is expected to be completed before the start of the school year.
