Crews on track to start moving traffic to new bridge next spring
MARYSVILLE – Crews working to replace the aging State Route 529 bridge over the Ebey Slough will reach a major milestone this month when they finish setting the girders that will form the backbone of the new wider, taller bridge.
Less than a year after starting construction, crews working for the Washington State Department of Transportation (WSDOT) began setting 49 girder sections the first week of June. They expect to have all of the girders in place by the end of the month, when they’ll shift their focus to building the road deck on the bridge.
“Regular commuters have probably noticed this very visual sign of our progress during the last two weeks,” said Janice Fahning, WSDOT project engineer. “We worked hard this winter and spring to get to this critical milestone. It’s the last major step in getting the new bridge ready to open to traffic next April.”
Each girder section is seven feet tall, weighs about 31 tons and is 100 to 135 feet long – about the length of three school buses. Crews will assemble the sections to form seven massive girders that will span the slough with a new 680-foot-long bridge.
“Girders are an integral part of any bridge because they make up the spans of the structure and help distribute the traffic load to the bridge’s foundations,” said Fahning. “Once all of the girders are in place and bolted together we’ll start building the deck for the new bridge.”
Crews are building a new four-lane, fixed span bridge next to the existing bridge. They expect to begin shifting northbound SR 529 traffic to the new bridge by April 2012, with all traffic on the new bridge by August 2012. They’ll then demolish the old bridge. Work on the $42.3 million project is expected to be complete by the end of 2013.
SR 529 is a main commuter route between Marysville and Everett and is used by about 17,000 drivers each day. The 86-year-old existing bridge is at the end of its service life and does not meet current traffic needs. The new bridge will have two lanes, separate bicycle lanes and sidewalks in each direction of the bridge.
