The folks at WSDOT sent us the following road closure info for Seattle, including the scoop on bicycle detours.
* * * * * * * * * *
We’re closing Alaskan Way S. between S. Royal Brougham Way and S. Atlantic Street starting Monday, Feb. 14. However, the existing Alaskan Way S. multi-use path will remain open during the road closures. This means bicyclists will not need to detour their route while construction is happening on Alaskan Way S.
During President’s Day weekend, crews will close First Avenue S. from S. King Street to S. Royal Brougham Way. Bicycles and pedestrians also will be detoured to the Alaskan Way S. multi-use path. Here are the details:
Alaskan Way S. road closures
Beginning Monday February 14, both directions of Alaskan Way South between S. Atlantic Street and S. Royal Brougham Way will close to vehicle traffic for one week. On Monday February 21, southbound Alaskan Way S., between S. Royal Brougham Way and S. Atlantic Street, will reopen to vehicle traffic. Northbound lanes will remain closed at least until 2013. During the closure, crews working for the Washington State Department of Transportation will build the foundation supports for a new side-by-side roadway that will replace the southern mile of the Alaskan Way Viaduct.
We will post bicycle detour signs on the Alaskan Way S. multi-use path directing cyclists around the full or partial Alaskan Way S. closures:
- Northbound cyclists will see one bicycle detour sign just south of S. Massachusetts Street, one at S. Massachusetts Street, and a third stationed at S. Royal Brougham Way.
- A southbound bicycle detour sign will be posted on the existing bicycle/pedestrian path at S. Royal Brougham Way directing cyclists to the west side of Alaskan Way S. The southbound path continues south on East Marginal Way on the west side of the street.
First Avenue S. road closure
Friday, Feb. 18 at 7 p.m. until Monday, Feb. 21 at 5 a.m., both directions of First Avenue S. will be closed to all traffic between S. Royal Brougham Way and S. King Street. During the closure crews will demolish the SR 99 on-ramp from First Avenue S. and rebuild it in a new location. This ramp work is the first step in building a four-lane construction detour that will connect the viaduct’s downtown waterfront section to the SR 99 replacement roadway between S. King Street and S. Royal Brougham Way.
Bicycle and pedestrian access to First Avenue S. and the Alaskan Way multi-use trail
- Northbound detour: Bicyclists and pedestrians will be detoured from First Avenue S. to westbound S. Royal Brougham Way to the multi-use trail located along the east side of Alaskan Way S. They may follow the multi-use trail to King Street or points further north.
- Southbound detour: Bicyclists and pedestrians will be detoured to the Alaskan Way S. multi-use trail via King Street. They may access First Avenue S. by turning left onto S. Royal Brougham Way or follow the trail to points further south.
Pedestrian access to First Avenue S. and the Alaskan Way S. multi-use trail
- The sidewalk along the east side of First Avenue S between S. Royal Brougham Way and S. King Street will be closed to pedestrians. We will place a “local businesses are open sign” and provide a signed detour routing pedestrians onto Occidental Avenue S. and Railroad Way. Pedestrians will be able to access to businesses along the east side of First Avenue S. from Occidental Avenue S and Railroad Way.
- Pedestrians will be able to access the Alaskan Way S. multi-use trail from S. King Street and S. Royal Brougham Way. All of the sidewalks and ramps on S. Royal Brougham Way and S. King Street will be ADA accessible.
