Mercer Corridor Project: Partial closure of Fifth Avenue N at Mercer Street April 26-28

The Seattle Department of Transportation (SDOT) advises travelers of the partial closure of the intersection of Fifth Avenue N and Mercer Street scheduled for Saturday, April 26 to Monday, April 28.

Beginning the morning of Saturday, April 26 at 4 a.m. through Monday, April 28 at 5 a.m., the intersection of Fifth Avenue N and Mercer Street will be partially closed to traffic to accommodate roadway excavation and preparatory work for concrete paving. During the closure:

  • Southbound Fifth Avenue N will be fully closed to traffic between Roy and Mercer streets. Travelers heading south on Fifth Avenue N will be detoured to westbound Roy Street and Fourth Avenue N in order to reconnect with Fifth Avenue N via eastbound Mercer Street.
  • Travelers heading north on Fifth Avenue N will be detoured at Republican Street to continue north on Fourth Avenue N toward the Seattle Center and the Queen Anne neighborhood.
  • Local access to businesses and properties will be maintained at all times.
  • Pedestrians will be detoured and advance signage will be posted.
  • Travelers heading toward Queen Anne and the Seattle Center from I-5 and Downtown should use westbound Broad Street, Denny Way, and northbound First Avenue N as an alternate route.
  • Mercer Street between Taylor Avenue N and I-5, Broad Street, Dexter Avenue N, SR 99 and the I-5 on- and off-ramps at Mercer Street will remain open during the weekend work.
