Oklahoma Prepares For Its Largest Ever Bridge Move & Installation

Construction of two 45-foot-tall bridge structures began in June 2017 in the right-of-way along the I-235/I-44 interchange project. This weekend I-235 will be closed in this area to move the completed structures to their new home over I-235 just south of N. 50th St. Calling it a “spectacular feat of engineering,” the Oklahoma Department of Transportation is nearing the day for moving and installing a 4-million-pound steel railroad bridge over Interstate 235 in Oklahoma City. “Due to their size and weight, it will be a slow and steady operation to move the two bridge spans into place, taking up to a full day per span,” ODOT says. “The bridge structures will be hoisted up on self-propelled mobile transporters and inched along the highway into their new position over the interstate.” American Bridge Company oversees the project to move the 45-foot-tall BNSF railroad bridge structures from their construction site a quarter mile away and install them. The interstate was closed between I-44 and North 36th Street for three days starting January 26 for the project. The installation had been delayed because of high winds and could face delay again depending on the forecast.
