As many of the nation’s bridges continue to fall into disrepair or obsolescence, some local authorities are coming up with innovative ways to make the necessary bridge upgrades without creating additional commuter logjams.
Last month, the Oklahoma Department of Transportation (ODOT) installed a two-span, 45-foot-tall, 4-million-pound prefabricated railroad truss bridge along a portion of Interstate 235 in a matter of days. Crews built the bridge offsite, eliminating the traffic jams and road closures that typically occur when infrastructure of this magnitude is built onsite. The bridge is part of the $88 million “Off Broadway” highway improvement program, the largest project in ODOT history.
