Sound Transit’s ongoing expansion of Seattle’s light rail consists of a number of different extensions due to be completed in 2023. Hoffman Construction was contracted along with JV partners Kiewit and Stacy and Witbeck to build new expansions consisting of track alignments, stations, and garages. 

Find out how Hoffman Construction overcame coordination challenges by:
