US-2 Dover Bridge Replacement

Location: Dover, Idaho

DEA provided full-service construction engineering and management services for this $21.6 million American Recovery and Reinvestment Act (ARRA) project. Work involved realigning and reconstructing 1.6 miles of US-2, and replacing the existing, functionally obsolete Dover Bridge in northern Idaho with a new 1,219-foot-long concrete/steel girder bridge. Major project work consisted of bridge construction and demolition, pile driving, new five-lane roadway construction, mechanically stabilized earth wall construction, and new wetland construction. The project was particularly challenging because most of it was constructed through existing wetlands alongside and over an active railway. This project highlights the effectiveness of DEA’s construction team in change management given the challenging materials and subsurface conditions and sensitive issues related to work over the BNSF Railroad right-of-way. Inspection services included tracking and evaluating quality compliance/quality assurance testing, compiling quality documentation for workmanship and materials, determining appropriate pay quantities, and reviewing the contractor’s records for compliance to labor requirements, as well as monitoring for compliance with environmental regulations.
