To reach the milestone in one night, crews used trucks to haul 10 bridge girders through the roadway barrier onto the wide shoulder of US 290 main tracks where crane operators then lifted and placed the girders onto heavy duty pads. support at the top of previously constructed columns and caps. The successful placement of the bridge girders supports upcoming widening operations on Old Fredericksburg Road, which include the installation of a permanent steel deck, the formation of bridge overhangs, and the placement of rebar for the future decks and bridge barriers. This same operation will take place in the coming weeks at Monterey Oaks Boulevard.

“The start of bridge widening activities on Old Fredericksburg Road and Monterey Oaks Boulevard signifies significant progress on TxDOT’s Oak Hill Parkway project,” said John Rempe, PE, executive vice president of Balfour Beatty and regional director of civilian operations in the southwest. “I commend our bridge crews for their collaboration in the safe execution of this operation which is a step forward in reducing traffic congestion and improving long-term mobility along the United States 290 and SH 71 in Austin.”

Since the project began last summer, the CRC joint venture team has completed its first major traffic shift west of Circle Drive and is preparing for its second major traffic shift where the first permanent frontage roads will be lines up at the west end of the Oak Hill Promenade Corridor. The team continues to work on constructing over 10 different retaining walls along the project corridor, which are a mix of studded walls, cast-in-place walls and drilled noise barriers. Delivery of over 10 bridge structures is also underway where team members have completed drilling shafts, columns, caps, abutments and now bridge girders.

Additionally, due to the location of the project, large trenchers and milling machines are used during the excavation work. Nearly 400,000 cubic yards have been excavated to date, out of approximately 2 million cubic yards, to complete the project.

When complete, the Oak Hill Parkway project will reconstruct and widen US 290 from the east end of Circle Drive to Loop 1 (MoPac Expressway) and SH 71 from US 290 to Silvermine Drive. The newly designed roadway will consist of constructing two to three main lanes as well as adding two to three frontage lanes in each direction. An overpass for the US 290 mainlines over William Cannon Drive will also be built, along with direct-connect flyovers between US 290 and SH 71.

Other components of the project include bicycle and pedestrian amenities along the entire corridor, cross-intersection improvements, turn-around lanes, upstream water retention, stormwater retention, and water quality treatment ponds.

The Oak Hill Parkway project is expected to be completed in 2026.
