Check out six upcoming or ongoing transportation projects across the Austin metro, including major highway projects, a railroad bridge and a shared-use path.

Upcoming projects

Crystal Falls Parkway rail bridge

Project: Leander city officials are considering building a railroad bridge over Crystal Falls Parkway at US 183, removing the current ground-level rail crossing and allowing traffic to flow uninterrupted by passing trains.

Update: The city is actively seeking a $40 million grant from the Texas Department of Transportation, as well as additional funding opportunities. The design phase is expected to take around two and a half years, followed by roughly three years of construction.

I-35 Capital Express Central project

Project: The Texas Department of Transportation’s multibillion I-35 overhaul, which broke ground last October, will add two nontolled high-occupancy vehicle lanes along the roughly 8-mile stretch from Hwy. 290 to Hwy. 71. The project also includes removing upper decks, sinking sections of the roadway about 25 feet, and widening the corridor to 17-22 lanes.

Update: According to TxDOT, the northbound I-35 Riverside Drive exit 233 and Holly Street entrance ramp exit 234A will be permanently closed as crews prepare for the reconstruction of Lady Bird Lake bridge. Site work also began Feb. 2 at the Edgewood drop shaft, which TxDOT officials say marks another milestone as all nine drop shafts will be under construction for the drainage tunnel and pump station segment of the project.
