Busy construction season continues in Snoqualmie Valley

The Ames Lake Trestle Bridge and Duvall Slough Bridge will be closed for an extended period of time as crews work to improve driver safety.

King County Road Services (KCRS) is making the most of the warm and dry weather as contractors work to complete several major construction projects in unincorporated areas around the Snoqualmie Valley.

According to a King County press release, drivers should expect delays or total closures at the following locations and are encouraged to “pack their patience” when hitting the road.

“We share the season with summertime events, outdoor sports and concerts, weekend bike rides, and walks with friends,” said KCRS Director Tricia Davis. “Travelers can get the most out of summer if they know before they go. Road Services makes it easy because there are so many ways to stay on top of our construction work.”

Duvall Slough Bridge

The Duvall Slough Bridge on NE Duvall-Woodinville Road will be closed for six weeks, beginning July 15, as crews work to partially remove and replace the 75-year-old bridge deck.

Portions of the bridge deck, expansion joints and both approaches will be rebuilt to extend the life of the bridge and improve safety.

Ames Lake Trestle Bridge

The Ames Lake Trestle Bridge on Ames Lake-Carnation Road NE began its eight-month total closure on June 24 to allow crews to remove and replace the 100-year-old timber trestle bridge.

The stronger, more stable 38-foot-wide bridge will straighten the roadway, increase sight lines and improve safety and traffic flow.

NE Tolt Hill Road

A 14-week, single westbound lane closure began May 28 on NE Tolt Hill near Carnation and SR 203 as contractors build a new retaining wall along the west approach to the Tolt Bridge.

The new wall will improve the safety and stability of the road and neighboring hillside.

King County recommends that drivers rely on services like Google Maps or MyCommute for up-to-date road closures and restrictions. Alternative routes can be found on the King County website.
