Construction ramps up at the I-90/SR 18 interchange

Work on SR 18 makes way for road widening and wildlife habitat improvements

SNOQUALMIE – Major construction for the Interstate 90/State Route 18 interchange improvement project begins in late spring. In the meantime, people traveling near the I-90 and SR 18 interchange should plan for increased congestion in the coming weeks as contractor crews install work zone signs and clear trees throughout the project area.

Slow down – lives are on the line. 

In 2023, speeding continued to be a top reason for work zone crashes.

Even one life lost is too many.

Fatal work zone crashes doubled in 2023 - Washington had 10 fatal work zone crashes on state roads.

It's in EVERYONE’S best interest.

95% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
