BNSF North Spokane

Location: Spokane, Washington

The Washington State Department of Transportation (WSDOT) designed a major expansion and realignment of US 395 through Spokane, Washington. The new US 395 alignment approximately follows an alignment of existing BNSF mainline railroad tracks, requiring the BNSF alignment to be relocated. BNSF will construct 56,000 feet of mainline, lead, and industrial tracks to the new alignment during several stages, which run along the location of the railroad’s former Hillyard Yard, once a major locomotive maintenance and repair facility. The railroad realignment was designed in conjunction with WSDOT’s US 395 North Spokane Corridor project. DEA is the prime consultant for this railroad realignment project including tracks, three new railroad grade-separation bridges, retaining walls, grading and drainage improvements, access roads, utility relocations and protections, and signal and communication facilities.

Critical issues to the success of this project included coordination with BNSF and WSDOT, working within train operating parameters, geotechnical solutions for the bridge and retaining wall foundations, and structural design.
