our projects
Ohio Department of Transportation (ODOT) | CUY 480-7.14
This project took place in a section of I-480 that is the major confluence of I-71, SR-237, and the ramps that serve Cleveland Hopkins International Airport, as well as the nearby rental car facilities. This corridor is particularly complex given the mix of local and non-local motorists, coupled with multi-lane weaves, as well as areas of lane-add/-drop. Plagued by delays during the evening peak hour, the Ohio Department of Transportation (ODOT) selected Patrick to utilize performance based practical design for the reconfiguration of the existing westbound (WB) lanes along I-480 to increase the number of lanes from two to three and improve the existing weaves without roadway widening. The project also involved the rehabilitation of three WB bridges (CUY-480-0792, CUY-480-0805, CUY-480-0832) and included deck overlays, expansion joint replacements, end cross-frame replacements, barrier replacements and retrofits, and abutment patching.
