Travelers who use the Mercer Corridor have much to look forward to as construction is expected to wrap-up later this year. As pavement is poured, lanes are added, sidewalks poured, bike lanes completed and signal timing adjusted, SDOT will maintain its commitment to safety to all those who work, live and travel in the corridor. Though traffic capacity is limited, the project opened two new westbound lanes between Ninth Ave N and Queen Anne Ave N last summer. This provides a much improved, direct route from I-5 to Seattle Center, Uptown and Queen Anne, and it also eliminates some of the challenges between turning vehicles and pedestrians.
Work in the past six months has focused on Mercer between Fifth Ave N and Ninth Ave N, and south along Fifth Ave N. Installation of new signals, sidewalks, and accessible ramps has required that traffic lanes, sidewalks, and crosswalks be closed to protect pedestrians and others from construction activities. Pedestrians have had to cross the street at signalized intersections and sometimes travel two or three blocks out of their way to avoid the construction zones. This is inconvenient, but necessary to maintain safe, accessible connections during construction. Pedestrian maps highlighting closures and detour routes are posted on our project website as well as on sidewalks in the project area. Here’s a link: http://www.seattle.gov/transportation/mercercorridor.htm
As work progresses, more corners and crosswalks are opening up with improved ramps and sidewalks. All new sidewalks and curbs are constructed to meet the current Americans with Disabilities Act standards for mobility providing safe travels for all users in the corridor.
Work will continue near the intersection of Dexter Ave N and Mercer St where temporary configurations have been in place on both streets since July of last year. Temporary roadways were constructed so that crews could safely work on major utility relocations on both Mercer St and Dexter Ave N. Both roadways and corresponding curvatures drivers experience will be removed this year, starting with Mercer St the weekend of February 7.
During this weekend closure, crews will also stripe the eastbound lanes with their final markings. Pedestrians will also experience a noticeable change in their routing as the temporary roadways are removed. Following the February 7 weekend closure, pedestrians will be moved from the south side of Mercer St to new sidewalks on the north side of Mercer St between 5th Ave N and Dexter Ave N. The new separated bicycle path will be in place adjacent to the sidewalk, but crews will wait for drier weather to add channelization markings on the bike path.
