As reported by the Washington State Department of Transportation, the I-90/SR 18 Interchange Improvements project near North Bend and Snoqualmie has some important traffic changes taking place beginning the week of August 21 as crews finish the west half of Lake Creek bridge on State Route 18, just south of Interstate 90.
An overnight traffic shift on SR 18 near Lake Creek bridge will take place just south of I-90 and SE 104th Street. WSDOT will move the work zone to the east side of the road to finish Lake Creek bridge and will shift travel lanes over the finished half of the bridge. People using SE 104th Street will have the same access as the previous traffic shift.

Lowered speed limits started Monday, August 7
WSDOT lowered speed limits on State Route 18 just northeast of the Tiger Mountain summit to help protect highway construction crews and people traveling through the work zone. Speed radar signs may be posted before the beginning of the school year to remind drivers to slow down.

Schedules are subject to change. Ongoing lane closures occur each night, Mondays through Thursdays, between the interchange and Lake Creek.
