About Us

Cascade Bridge, LLC is a heavy highway general contractor based in Vancouver, WA. We specialize in bridge construction and rehabilitation. Formed in 2001 by Dave Mingo and Rick Phillips, Cascade Bridge has built more than 110 projects throughout Oregon, Washington and Idaho in its first 20 years.

Our bridge construction projects encompass multiple bridge types including precast girder, precast slab, cast-in-place box girder, cast-in-place flat slab, cast-in-place arch and steel girder bridges. Additional types of construction include retaining walls, soldier pile walls, tieback walls, mechanically stabilized earth walls, dams, pile driving, shoring, cofferdams, structural concrete slabs, seismic retrofits and micro silica/polymer overlays.

Cascade Bridge has extensive experience building projects with multiple work locations, high traffic volumes on major freeways, close railroad proximity and complex existing/future utility networks. We excel in bridges built over water using our company owned work bridge trestle system.

While a majority of Cascade Bridge’s work has been secured via the traditional bid-build delivery method, Cascade Bridge has extensive experience working on design-build projects. We take pride in our ability to self-perform on our projects. We have accumulated a large equipment fleet and significant material resources over the past 20 years along with a bonding capacity such that we can tackle a majority of the infrastructure projects that our bid in our region.
