Project anticipated to begin in spring 2024
Two engineers inspect the Ames Lake bridge from the bucket of an under-bridge-inspection-truck (UBIT) truck. The bridge will be replaced in 2024.
King County intends to advertise to contractors in December 2023, and construction is anticipated to start in March or April 2024. The next community meeting about the project will be held online in early 2024, check back in December for the exact date.
During construction, Ames Lake-Carnation Road, between W. Snoqualmie Valley Road NE and NE 52nd Street, will be closed at the bridge location. The work will take approximately eight (8) months.
