One lane on southbound Dexter Ave. N will remain open at all times. Bicyclists will be required to merge with vehicular traffic.

Intermittent lane closures on Roy Street through fall of 2014

Roy Street between Fifth Avenue N and Queen Anne Avenue N will continue to have intermittent lane closures during off-peak travel times between 9:00 a.m. and 2:00 p.m. to accommodate construction activities within the work zone. Please pay attention to flaggers stationed in the roadway.

Intermittent lane closures on Mercer St. through fall of 2014

Mercer St. between 1st Ave. N and 9th Ave. N will have intermittent lane closures during off-peak travel times between 9:00 a.m. and 2:00 p.m. to accommodate construction activities within the work zone. One lane on westbound and eastbound Mercer St. will remain open at all times.

Alternate routes through the corridor

With the closure of Broad St. and two-way traffic on Mercer St., Roy St., and Queen Anne Ave. N now in place, please consider using the following alternate routes during construction:

  • Use Roy St. as an alternate eastbound route through the Uptown neighborhood.
  • To access north Queen Anne, use Mercer St. and then proceed north on Queen Anne Ave. N.
  • Use eastbound Denny Way, 2nd Ave. or 5th Ave. to access I-5.
  • Use SR 99 and Elliott Ave. W as alternate routes to and from your final destination.
  • Access southbound SR 99 from Aloha or Valley streets.
  • To access northbound SR 99, use 2nd Ave. or 5th Ave. south from Denny Way and turn left on Battery St.

In its final configuration, Mercer St. will maintain three lanes in each direction between 5th Ave. N and I-5. All lanes will be operational by the summer of 2015. Until that time, Mercer St. will operate in a temporary configuration with two lanes in each direction.

Route maps for navigating the corridor

Crews continue to monitor intersections throughout the corridor

We appreciate your patience as we work to improve flow throughout the corridor. Please continue to use alternate routes where possible and notify the project with any feedback, suggestions, or questions atmercerinfo@seattle.gov or (206) 419-5818.

Lane reductions on Mercer St. will continue throughout the West Phase of the Mercer Corridor Project, which is anticipated to be completed in mid-2015. Construction of this $95 million project will take approximately 2.5 years.
