mercer_logo_200This week, crews will continue to focus on underground utility work on Valley Street and Broad Street and will expand construction activities on Westlake Avenue N north of Mercer Street.

Activities this week include:

  • Westlake Avenue N work including underground utility installations and roadway demolition and restoration. Please note, this work will require the rechannelization of 9th Avenue N the evening of April 2 beginning at 8:00 p.m.:
    • Overnight on Tuesday, April 2, crews will complete the rechannelization of 9th Avenue N to allow for two northbound lanes and one southbound lane on 9th Avenue N near Aloha Street. During the closure for rechannelization, all northbound 9th Avenue N traffic will be detoured onto eastbound Mercer Street and northbound on Westlake Avenue N. One southbound lane on 9th Avenue N will be maintained as crews complete the work.
    • Beginning Wednesday, April 3, northbound traffic on Westlake Avenue N will be detoured onto Mercer Street and then to 9th Avenue N to continue north.
    •  For the first few days as traffic flow adjusts, uniformed police officers will be positioned at key intersections to facilitate traffic flow during peak travel times:
      • 9th Avenue N and Mercer Street
      • Westlake Avenue N and Mercer Street
    • Local access to Westlake Avenue N businesses between Mercer and Valley streets will be maintained. No through travel onto Valley Street will be permitted.
    • This configuration will be in place for approximately four months while crews complete utility improvements and rebuild the roadway on Westlake Avenue N.
  • Continue electrical vault installation on Broad Street between 9th Avenue N and Westlake Avenue N.
  • Continue landscaping installation on Fairview Avenue N between Valley Street and Mercer Street and on the south side of the I-5 on-ramps at Mercer Street.
  • Continue Seattle City Light and communications duct bank work on Valley Street.

Traffic engineers will continue to:

  • Monitor traffic flow on Mercer Street and newly re-opened Fairview Ave. N.
  • Monitor traffic flow at the Dexter Avenue N and Mercer Street intersection.
