Contracting Opportunities with Interstate Bridge Replacement Program

The Interstate Bridge Replacement Program (IBR) is constructing a safer multimodal connection for travelers crossing the Columbia River, while building stronger communities by supporting economic opportunity. Delivering the investments proposed by the IBR Program will require thousands of workers skilled in trades ranging from concrete and steel to project management and quality assurance. A skilled workforce that is ready to meet the challenges of the future is critical to the Program’s success.
