Over the weekend we worked through the night to transport and set the first five girders north of Pine Street. These large concrete beams are filled with reinforcing steel and span across the support piers and over the railroad tracks for the new bridge connecting the waterfront to Belltown. These girders, up to 75 tons each and nearly 150 feet long, were carefully set with the use of two cranes. More girder setting is scheduled for this weekend and early next week.

A goal of the future waterfront is to create intersections that are designed to provide safe, accessible crossings for people of aIl ages and abilities. Shown below is a widened curb ramp on Main Street at Alaskan Way. This area is part of the future Pioneer Square East West Pedestrian Improvements, which prioritizes improved sidewalks and accessibility to connect Pioneer Square to the waterfront, in addition to being part of the Alaskan Way improvements already well underway.

In partnership with Friends of Waterfront Seattle (Friends), we are pleased to share that the newly rebuilt public park, Pier 62, opened to the public on Sunday, September 20. Since December 2017, we replaced 884 aging wood piles with 175 steel piles and poured 214 new concrete deck panels. With that work now complete, the new Pier 62 provides approximately 40,000 square feet of new park space that will be used for a range of both passive and active recreation, arts and cultural activities. The space will be managed through a partnership with the Seattle Department of Parks and Recreation and Friends. Visit waterfrontparkseattle.org/pier-62/ for more information and future events at Pier 62.
