US2 Flyover

PROJECT OVERVIEW

Two bridges were to be built for the US 2 Highway expansion connecting North Spokane to the 1-90 corridor. The highest point was 120′ above the roadway. Special “Angel Wings” were designed and built to use where aerial lifts could not be used. Apex Erected bridge sections over piers that created a balance cantilever. Once two cantilever sections were erected the drop in sections would be erected to complete the span. Extreme heat meant Apex had to drop in the sections at the right time of day so that the steel would fit with the expansion sections. A complete span was erected in 1 day in 14 hour sifts.
