Public feedback needed on SR 520 Portage Bay Bridge options

SEATTLE – The public can view conceptual designs for a new State Route 520 bridge across Portage Bay – including possible cable-stay options – at an open house Saturday, May 19. The meeting is the latest opportunity for the public to give feedback as the Washington State Department of Transportation refines designs for the corridor from I-5 to the floating bridge.

The open house is scheduled from 9 a.m. to noon Saturday, May 19, at Seattle Preparatory School, 2400 11th Ave. E., Seattle. Bridge architect consultant Donald MacDonald will give a short presentation at 9:15 a.m. and SR 520 staff will be available to answer questions throughout the morning. WSDOT hired MacDonald to provide architectural guidance for the new SR 520 corridor west of the floating bridge. MacDonald has designed bridges around the world during the past 30 years, including the TriMet light rail transit and pedestrian bridge now under construction in Portland and the Eastern Span of the San Francisco Oakland Bay Bridge scheduled for completion in 2014.

Models and conceptual architectural sketches of the Portage Bay Bridge options under consideration will be on display at the open house. The models and sketches include bridges supported by beams, girders and cables.

Public feedback on the benefits and trade-offs between the different bridge design options will help drive future design decisions. Additional open houses are planned this summer as part of WSDOT’s Seattle Community Design Process. Materials from previous open houses are posted online.

The meeting site is accessible to people with disabilities. Accommodations for people with disabilities can be arranged in advance by calling 206-770-3500.
