In the past, various PennDOT district offices have been responsible for repairing or replacing structurally deficient bridges. Although the department has experimented with bundling small numbers of bridges together in single contracts, this work is usually done one bridge at a time. The Pennsylvania Rapid Bridge Replacement Project had no history until the decision was made to pursue the bundling of a large number of bridges into a single contract to be procured on a P3 basis.
