What we’ve been up to: Mercer Corridor Project’s Substantial Completion Photo Blog

In August 2015, the West Phase of the Mercer Corridor Project reached substantial completion – meaning all major closures and improvements to the corridor are complete! All that remains is a localized closure on Roy St. and some low-key maintenance items with associated lane closures around the area, including landscaping, striping, and a few repairs. Here are a few of the key improvements throughout the corridor:









New, separated bike lanes and a widened pedestrian walkway were installed along the north side of Mercer St. in addition to a widened sidewalk on the south side. Trees and landscaping provide a buffer from the roadway. Here you can also see the expanded underpass beneath SR 99. The widened span, with elimination of the center columns, brings in more light.










Widened, two-way Mercer St at 5th Ave. N.: there are three lanes of eastbound and westbound traffic as well as updated intersections, crosswalks, and landscaping. Corners at this and all intersections have been updated to provide safe, accessible crossings for all users.



Looking south – the intersection of Dexter Ave. N and Mercer St., showing an updated configuration of traffic lanes, bike lanes, and the pedestrian crosswalk. Signals and signage at this intersection help eliminate conflicts between right-turning traffic and the many pedestrians and bicyclists who cross Mercer at this intersection.











The intersection of 5th Ave. N, Thomas St., and Broad St. has been reconfigured significantly, improving access for pedestrians at this major entrance to Seattle Center, thereby accommodating traffic volumes on Fifth Ave N and Broad Street, and separating pedestrians and delivery vehicles on the Seattle Center campus.
