Pier 62/63 Phase 1 Rebuild
As part of the Waterfront Seattle Program, the City of Seattle will rebuild Pier 62/63 in partnership with Friends of Waterfront Seattle.
The rebuilt pier will be a place to stroll, enjoy views, play and once again host events like the “Summer Nights at the Pier” concerts. It also adds a major new feature – a floating dock for access to the water.
The City will rebuild the southern half of the pier (Pier 62) and retain the northern half (Pier 63) in place. This will include replacing the aging wood pilings and deck, retaining the existing size and shape of the piers. The rebuild will also provide new railings, lighting, utilities and a floating dock. The southern half will be constructed at the same time as the seawall replacement adjacent to Pier 62/63.
The City is moving ahead with design and permitting. The preliminary budget for design and construction of the southern half of the pier is $29M. Friends of Waterfront Seattle have committed to raise $8M of the total project cost. Construction is expected to begin in fall 2017 and be completed by 2019.
Pier 62/63 Rebuild Plan
A Flexible Public Space
The rebuilt Pier 62/63 will be a flexible space with broad views of Elliott Bay, the Olympics and the Seattle skyline. It will be a place for strolling and viewing, recreation and cultural events, including concerts. The rebuild will include public art commissions from acclaimed artists Ann Hamilton and Stephen Vitiello.
New Floating Dock
A new floating dock will be added on the southern edge of Pier 62/63. This new access to Elliott Bay will provide short-stay moorage for small boats and a launch point for cultural events such as the Salmon Homecoming or a small floating farmers market showcasing local goods.
When Seattle’s waterfront was developed, Elliott Bay lost many of the habitat features associated with its native intertidal habitat, including sloping beaches, crevices and vegetated hiding places for fish.
In order to improve the ecosystem and restore the salmon migration corridor, the Seawall Project has installed in-water features that improve habitat for juvenile salmon, as well as habitat-friendly sidewalks with glass blocks that let light pass through to the water below.
To further support the habitat with natural light, the rebuilt Pier 62/63 will include a section of grating along the nearshore to increase the amount of light to the water below.
The Office of the Waterfront, together with Friends of Waterfront Seattle, held a public open house on the Pier 62/63 Phase 1 Rebuild:Thursday, June 23, 5 - 7 PM

Marion Street Bridge
As part of the Waterfront Seattle Program, the City of Seattle, in cooperation with the Washington State Department of Transportation (WSDOT), will rebuild a portion of the Marion Street Bridge. The rebuild will happen as part of the removal of the Alaskan Way Viaduct and reconstruction of Alaskan Way.
The bridge provides an essential pedestrian connection between the multimodal ferry terminal at Colman Dock and major destinations in downtown Seattle including employment and retail, a new transit hub on Columbia Street, and Seattle’s waterfront. The bridge is utilized by the majority of the more than 5 million foot passengers who use Colman Dock annually. The replacement of the Marion Street Bridge is funded by WSDOT as part of the Alaskan Way Viaduct Replacement Program.
Replacing the Marion Street Bridge
The Marion Street Bridge is comprised of three segments built between 1950 and 1970, starting with the western segment over Alaskan Way moving east towards Western Avenue. This project will replace the span across Alaskan Way, from Colman Dock to the east side of Alaskan Way. During Seawall construction, this span was replaced with a temporary structure, which must be removed as part of the removal of the viaduct. The segments east of Alaskan Way to Western Avenue will be replaced in a future phase by the City of Seattle. The segment from Western Avenue to 1st Avenue is in good condition and will be retained.
- Provide grade separated connection for patrons of the Colman Dock facility that improves dock and street operations as well as pedestrian circulation.
- Provide cost-effective, durable and context sensitive design that enhances the waterfront as a place for people.
- Provide for effective pedestrian circulation within the Colman Dock hub between various modes including ferries, regional and local bus transit, Center City streetcar, private bus service, taxis and ride services and private vehicle pick up and drop off.
In addition to the above goals, the new Marion Street Bridge needs to meet technical criteria to accommodate pedestrians using bridge and vehicle traffic beneath the bridge and provide a safe and reliable pedestrian route. These criteria include:
- Minimum width between railings: 16 feet
- Minimum Alaskan Way Roadway clearance: 20 feet (to accommodate over-height truck loads)
- Promenade clearance: 14 to 16 feet
- Railing height: 36 to 42 inches
Based on the goals and criteria, three design concepts have been developed. The City intends to advance a final concept, with design complete by 2018. The City will work closely with WSDOT to ensure the Marion Street Bridge is cost effective, durable and fits with the context of the Colman Dock and the Waterfront. Construction will begin after the Alaskan Way Viaduct is removed, currently anticipated for 2019.
Concept 1 is a cast-in-place concrete structure. Key features include:
- Cantilevered approaches (to Colman Dock and toward 1st Avenue)
- Wide, short concrete pedestrian railings
- Simple and functional concrete design
- Shallow bridge depth to maintain a 20’ vertical clearance above Alaskan Way
Benefits of Concept 1 are:
- Relatively low construction cost
- Minimal long-term maintenance
Concept 2 is a structure that combines a standard concrete girder bridge and a cable-stayed bridge. Features include:
- Cable-stay columns (supported by concrete pylons which allow the bridge to be shorter than typical cable-stay bridges)
- Narrower bridge cross-section
- Open and transparent cable pedestrian railing
Benefits of Concept 2 include:
- Minimal maintenance (due to concrete support)
- Narrower footprint and height that typical cable-stay bridges
- Minimally interrupted views from the bridge from cable railing
Concept 3 is a steel and concrete Fink Truss Bridge. Key features and benefits of concept 3 are its slender profile and shallow bridge depth. However, these design benefits are also a drawback, and construction costs and maintenance of this bridge design are much higher than concepts 1 and 2. Because of these challenges, the City plans to carry forward concepts 1 and 2 only.
