RM 2900 Bridge Replacement in Kingsland

The Texas Department of Transportation has awarded an emergency contract to rebuild the RM 2900 bridge that was washed away in rushing floodwaters on the Llano River arm of Lake LBJ in Kingsland on Oct. 16, 2018. This was the largest flooding event in that location since 1935. Built in 1969, the RM 2900 bridge was designed to withstand a 50-year flood event. At the height of the flooding, the river was discharging an estimated 290,000 cubic feet of water per second.

Bridge improvements

The bridge will be widened to include 12-foot travel lanes, six-foot shoulders and a six-foot sidewalk. It will also be built as a “perch” bridge, meaning the middle of the bridge will be higher than the ends. At its highest point, the new bridge is expected to be about five-feet higher than the previous bridge.


Once construction begins, the contractor will work around the clock, when possible, to accelerate the construction. The bridge is expected to be complete in April, 2019. The construction cost is $17.3 million, which includes incentives for the contractor to complete the job as quickly as possible. Capital Excavation has been selected as the contractor for the project.

Traffic detours and updates

During project construction, drivers on RM 2900 in Kingsland will not be able to cross the Llano River/Lake LBJ, and must detour via alternate routes. There is a signed detour route utilizing the following highways: RM 1431, US 281, SH 71, and RM 2233.

Drivers are urged to pay attention to low-water crossings and remember to “Turn Around, Don’t Drown.” Please monitor electronic message signs near the construction site for daily updates, as well as Drive Texas and the Austin District's Twitter feed.
