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 2022, speeding continued to be a top reason for work zone crashes.

Even one life lost is too many.

Each year about 670 people are killed nationally in highway work zones. In 2022, Washington had six 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.
