The Oklahoma Department of Transportation (ODOT) and BNSF Railway (BNSF) partnered to replace a BNSF bridge over the busy I-235 in Oklahoma City, OK. The project was part of ODOT’s largest construction package in history, at $81 million, of which the truss bridge comprised $17.5 million. For construction of the additional lanes of traffic of I-235 to proceed, the existing two-80’ span, skewed thru-plate girder BNSF bridge had to be removed and replaced with two 275’ thru-truss spans. To minimize disruption to the 49 daily trains, the new bridge was constructed on an offset alignment. To minimize disruption to I-235 vehicular traffic (115,000 daily vehicles), the new spans were assembled offsite and transported on Self-Propelled Modular Transports (SPMT’s) down the highway during a planned weekend outage. Finally, a short closure of the BNSF track was utilized to shift the existing track onto the new track alignment and bridge. During the design phase, a location was identified as a laydown yard for assembly of the truss spans, which required coordination of other interchange construction. ODOT allowed two weekend highway closures for setting the truss, but agreed to a single three-day weekend. The move-in was completed in just two days. Given the project complexity, all project stakeholders including ODOT, BNSF and designers had specific meetings discussing the staging and construction steps required for the BNSF bridge replacement. This presentation will detail the planning and construction challenges faced with this project including specifics on the weekend closure and truss construction. *Missed this Session or want to view it again?
