American Bridge Company was in charge of 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 bridge was moved in two parts, with each bridge structure weighing 2 million pounds. The structures were hoisted onto self-propelled mobile transporters and inched along up the highway into their new position over the interstate, according to ODOT.
ODOT says this is the first time the bridge-moving technique was used in the state. By building the bridge on an off-site area, the agency was able to reduce the number of closures to I-235 during the interstate’s two-year, $88 million reconstruction and widening to six lanes.
