Bicycle and pedestrian routes

Bicycle and pedestrian routes

Bicycle and pedestrian routes will change during construction, but crews will maintain clearly marked paths, and outreach staff will continue to work with local bicycle and pedestrian organizations to communicate changes. 

South Atlantic Street overpass now open to traffic

In January 2014 we opened the South Atlantic Street overpass to the west of Seattle’s stadiums. This changed access to the existing bicycle path west of the new overpass. We are continuing to work with the bicycle community to maximize safety in this area.

Safety is a top concern for WSDOT, and we want to remind bicycle commuters that this area is still an active construction zone and a busy freight corridor. Caution should be taken when travelling through the intersection of South Atlantic Street and Alaskan Way South. Bicyclists travelling northbound must cross South Atlantic Street to the northeast corner of the intersection. From there, they must use the signalized pedestrian crosswalk to travel west and connect with the bicycle path.

After observing the traffic flow at this intersection and receiving feedback from bicycle commuters, we have made several adjustments to the bicycle route. We added candlestick barriers to clearly delineate the path and numerous signs to indicate the detour route. We will continue to monitor the area and make further adjustments as necessary.

A new permanent connection between the on-street bike lanes south of South Atlantic Street and the shared-use path from South King Street is scheduled to open by April 2014.
