KINGSLAND — Construction of the RM 2900 replacement bridge is about to hit a major milestone. Crews will set the first beams for the bridge on Thursday, Jan. 17. Ten beams, 80 feet in length, will be set on two bridge spans. Once the beams are set, the contractor will start prepping the surface to place panels and ultimately pour the driving surface. This process will be repeated, as additional shafts are drilled and columns poured.

Construction on the new bridge began in early November, and crews continue to work around the clock to rebuild the bridge as quickly as possible. The project team has encountered some unexpected obstacles, but it has not halted construction.

The recent draw down of Lake LBJ water levels by the Lower Colorado River Authority affected barge movements. “Our project team was able to find an alternative to moving barges to shore and back,” said TxDOT Austin District Engineer Terry McCoy. “The LCRA is a great partner and has agreed to hold water levels steady so that construction can continue.”

An additional crane was brought to the construction site to move supplies onto the barges, and shaft-drilling operations continue 24/7.

Another obstacle facing the contractor was debris below the lake bed surface. The debris is too deep to retrieve, so crews are now drilling through it.

“TxDOT is committed to getting this bridge back open for the Kingsland community and those who travel through this area,” said McCoy. “We will work diligently to resolve any issues that get in the way.”

The Oct. 16 flood along the Llano River arm of Lake LBJ was the largest flooding event since 1935. The power of the rushing water washed out the RM 2900 bridge.

The new bridge will be wider, including 12-foot travel lanes, six-foot shoulders, and a six-foot sidewalk. At its peak, the new RM 2900 bridge will be 5 feet higher than the previous bridge. Capital Excavation Company is the contractor.
