The Seattle Department of Transportation advises travelers of upcoming traffic and pedestrian route changes in the corridor.
Reminder: Final signal installation at Mercer Street and Dexter Avenue N June 23
Last week crews successfully completed final roadway striping on Mercer Street. Crews will place the intersection of Mercer Street and Dexter Avenue North in its final configuration by the end of the day Tuesday, June 23. Uniformed police officers will be stationed at the intersection between 9 a.m. and 3 p.m. to help facilitate traffic flow while crews work on the signals. Once signal work is complete, the following can be expected:
- Left turns from Dexter Avenue North onto Mercer Street will be allowed.
- Left turns from Mercer Street onto Dexter Avenue North will be allowed.
- Right turns from southbound Dexter Avenue N onto westbound Mercer Street will be allowed. Right-turning vehicles and southbound bicyclists will have separate signal phases with no right turns on red to reduce conflicts.
- Mercer will continue to operate with three eastbound lanes and two westbound lanes between Ninth Avenue North and Dexter Avenue North. Mercer Street may be reduced to two lanes in either direction between 9 a.m. and 3 p.m. weekdays.
- Northbound Dexter Avenue North will continue to operate with one lane between Republican and Valley streets.
Pedestrians and bicyclists shifted to the south side of Mercer Street on Monday, June 29
As early as Monday, June 29, pedestrians and bicyclists will be shifted from the north side to the south side of Mercer Street between Fifth Avenue North and Dexter Avenue North. For approximately two weeks, crews will close either the north or south sidewalk on Mercer Street between Fifth and Dexter between 7 a.m. to 4 p.m. to complete construction activities. Travelers can expect the following:
- A sidewalk on the north or south side of Mercer Street between South Lake Union and the Uptown neighborhood will be maintained at all times. Please pay attention to and obey sidewalk closures and detour signage for your safety and the safety of others.
- The sidewalk along the south side of Mercer Street is a shared pathway for pedestrians and bicyclists. Bicyclists should yield to pedestrians and may choose to dismount and walk their bicycles while using the shared sidewalk.
- You may call the 24-hour construction hotline at (206) 419-5818 to ask which sidewalk will be open for a particular day.
