WSDOT noted that contractor Rotschy Inc. intends to shift traffic to the new bridge by Wednesday afternoon.
Construction on the 36-foot-wide concrete bridge began last summer. Crews are building the new span 12 feet away from the existing, 85-year-old narrow steel-truss structure that was constructed during Herbert Hoover’s presidency.
Single-lane traffic will remain into June as crews continue to realign SR 6 to connect with the bridge and demolish the old span, as well as clean and restore the work zone.
WSDOT expects crews to demolish the old bridge in mid-May, complete construction and some landscaping work in June and finish the project by early July.
The 2005 gas tax and other state highway improvement funds are paying for the $6.3 million project.
