A detour is being designed for those who use the Santa Fe Trail pedestrian bridge, which will temporarily close as part of a $6.3 million project to improve the intersection where Gaston Avenue meets Garland Road and Grand Avenue.

The Texas Department of Transportation said in a release April 4 that crews are still revising the detour route for the bridge and that a planned closure starting this week would be delayed until further notice.

The bridge is part of the larger intersection improvements planned by TxDOT in partnership with the city of Dallas. Construction began in late 2021 and is expected to be completed in spring 2023, according to TxDOT.

The area is referred to as the "3G" intersection because of the roads that come together there. Initial work focused on removing medians and improving drainage structures, TxDOT stated.

The project includes the addition of bicycle and pedestrian lanes along with a new design to improve right-of-way turning in the intersection with more efficient lanes eastbound and westbound on SH 78. The existing SH 78 bridges will also be widened, the release stated.

Various lane closures are planned through April 9 as part of the construction. Drivers should expect delays, especially during peak travel times, the release stated.
