The 2.5-mile project will widen Hwy. 79 with an additional travel lane and add an underpass at Mays Street and an overpass at FM 1460. Adding a raised median, modifying driveways and installing shared-use paths on both sides of Hwy. 79 are also included in the project. The results of the environmental studies are expected by the end of the year, TxDOT public information officer Brad Wheelis said.

FM 1825/Pecan Street at FM 685/Dessau Road in Pflugerville

Drivers can expect several lane closures, including southbound FM 685 and on Pecan. Drivers needing a detour to southbound Dessau may use Immanuel Road.
