This weekend, the Seattle Department of Transportation will transition to two-way traffic on the following streets: Roy Street between Queen Anne and Fifth avenues North; Mercer Street between Fifth and Ninth avenues North; and Queen Anne Avenue North between Mercer and Roy streets. 

Also, Broad Street will permanently close. 

Beginning Saturday, May 31, at 4 a.m. through Sunday, June 1, at 5 a.m., access to northbound Queen Anne Avenue North will fully close to traffic from Roy Street to accommodate roadway striping and final two-way signal conversion. During the closure:

Travelers heading north from westbound Roy Street will detour onto southbound Queen Anne Avenue North and then right onto Mercer Street to proceed north on Second Avenue West. 

Travelers from downtown should use First Avenue North to westbound Mercer Street and Second Avenue West or Fifth Avenue North and Taylor Avenue North to access Queen Anne.

•Southbound Queen Anne Avenue North will reduce to two lanes between Roy and Mercer streets.

•Access to Queen Anne Avenue North from eastbound Roy Street will close. Turns onto westbound Roy Street from southbound Queen Anne Avenue North will not be allowed.

•Uniformed police officers will be placed at the intersection of Roy Street and Queen Anne Avenue North to facilitate traffic flow.

On Sunday, June 1, at 1 p.m., following the Race for the Cure, crews will begin converting the final section of Mercer Street to two-way traffic between Fifth and Ninth avenues North and permanently close Broad Street. 

During the conversion:

•Mercer Street will fully close to traffic between Fifth and Ninth avenues North. As intersections are converted to two-way traffic, roadways will reopen.

 •Uniformed police officers will be placed at impacted intersections along Mercer Street between Fourth and Ninth avenues North to facilitate traffic flow and direct vehicles around the closures.

•Denny Way and First Avenue North will remain fully open.

Broad Street will permanently close to traffic between Ninth and Fifth avenues North once Mercer Street reopens with two-way traffic between Fifth and Dexter avenues North, on the evening of Sunday, June 1.

After the weekend work, Roy Street will open to two-way traffic between Queen Anne and Fifth avenues North.

After opening Mercer Street to two-way traffic this weekend, construction will continue on Mercer Street between Fifth and Ninth avenues North, including at the intersection of Mercer Street and Dexter Avenue North, through mid-2015. During this phase of work:

•Mercer Street will have two lanes in each direction between Queen Anne and Ninth avenues North.

•Left turns from eastbound Mercer Street onto northbound Taylor Avenue North and northbound Dexter Avenue North will not be allowed.

•Access to northbound state Route 99 from eastbound Mercer Street will be via southbound Dexter Avenue North onto westbound Thomas Street.
