Closure necessary to lift, secure large overhead structure for new traffic signals

CLEARVIEW – Contractor crews will reach another milestone this weekend when they install what is known as a signal bridge across 180th Street Southeast in Clearview. Both directions of State Route 9 will close for 16 hours as the large structure is lifted into place across the highway. New traffic lights and signs will eventually be mounted on the structure.

Closure details
To place the 164-foot-long span, crews from Northwest Construction will close the following from 8 p.m. Saturday, Nov. 2, until noon Sunday, Nov. 3:

  • Both directions of SR 9 between 176th Street Southeast and 188th Street Southeast.
  • Both directions of 180th Street Southeast between Snohomish Avenue and 83rd Avenue Southeast.

Local access and detour route
Drivers can access local businesses and homes during the closure, but they will not be able to pass through the intersection from any direction. Through-drivers will follow a signed detour around the closure.

Signal bridge details
Two large cranes will lift the span at either end and hold it in place while crews secure it to existing foundations. The bridge will span the highway diagonally between the northwest and southeast corners.

The signal bridge at 180th Street Southeast will eventually hold dozens of new traffic lights and directional signs to guide drivers through the intersection. Each approach to the intersection will feature two left-turn lanes, a right-turn-only lane, U-turn capability and through lanes.

WSDOT is widening more than two miles of SR 9 from a two-lane road to a four-lane divided highway from State Route 524 north of Bothell to 176th Street Southeast in Clearview. The $58.7 million project also includes new U-turn locations, improved signage, highway lighting and guardrails.
