Completing the South Lander Street grade separation remedied long-standing congestion problems in the essential east-west corridor in Seattle’s Sodo District.
Project: South Lander Street grade separation
Client: Seattle Department of Transportation
In Seattle, the busy Lander Street corridor serving more than 13,000 vehicles, 1,400 pedestrians and 100 bicyclists daily was frequently blocked by train traffic, causing long lines of waiting cars and trucks. Completing the South Lander Street grade separation project remedied long-standing traffic congestion problems in the essential east-west corridor in Seattle’s Sodo District.
The new bridge is better designed to handle traffic from the Port of Seattle, King County Metro, regional freight, daily commuters and visitors. It has also reduced vehicle emissions and improved freight flow, supporting economic rejuvenation for Washington state.
