28-year design-build-operate-maintain contract awarded by Pennsylvania DOT to consortium of Plenary Walsh Keystone Partners to replace 558 aging bridges throughout the state. From a list of > 2000 structurally deficient bridges in the state, PennDOT identified 558 bridges in two regions of the state, securing right-of-way and permitting approvals for those bridges to accelerate the project, once awarded. All of the bridges are relatively small, many only single-span, two-lane structures of similar characteristics. Multiple factors were considered in selecting the bridges to be included in this program, including age, length, number of lanes, and average daily traffic, as well as impact on utilities, railroads, and a wide range of potential environmental impacts.
Project Delivery Method:
