The Sound Transit project requires unique solutions and special materials.

Crews are trucking in concrete rubble from the Alaskan Way Viaduct demolition to fill in the city's 3,140-ft-long Battery Street Tunnel.

Seattle’s 66-year-old Alaskan Way Viaduct isn’t going down without a fight, as demolition work originally scheduled for completion in early June is now expected to last through the summer.

Seeing parallels to a fatal crane accident in Texas in 2012, crane specialist Terry McGettigan believes the Seattle crane collapse will be shown to have similar causes.

A tower crane being dismantled collapsed Saturday, April 27 in Seattle, killing two ironworkers on the crane and two bystanders on the street below. 

Home to the largest ferry terminal building in the state, Colman Dock’s upgrades coincide with the new tunnel and viaduct removal work near the waterfront. 

As Seattle's new State Route 99 tunnel welcomes vehicle traffic, crews continue to demolish the aging (it opened in 1953) and vulnerable Alaskan Way Viaduct along the waterfront.
