TxDOT BS 71-F Bridge over Colorado River

The new TxDOT bridge will replace the existing truss bridge over the Colorado River in Columbus, Texas.  Stiver Engineering provided construction engineering to the bridge contractor with cofferdam designs for crane access on both banks of the Colorado River.  The cofferdams allowed the crane to get closer to the center of the proposed bridge so that the bridge beams could be lifted and installed.  The cofferdam was constructed using driven sheet piles, wales and cross ties.
