Plan ahead overnight closures as crews finish striping state Route 900.
Drivers can expect single-lane closures on eastbound and westbound state Route 900 from 8 p.m. – 5 a.m. Monday night through Thursday morning.
The westbound Interstate 90 off-ramp to state Route 900 closes at 8 p.m. – 5 a.m. Wednesday and Thursday. The state Department of Transportation plans to detour drivers the exit at West Lake Sammamish Parkway Southeast.
The striping comes as the DOT completes a long-running effort to widen state Route 900 through Issaquah. Work on the $33.9 million project started in August 2008.
The transportation agency opened almost a mile of widened lanes between Southeast 82nd Street and Newport Way Northwest in April. The stretch carries about 16,000 vehicles per day.
Crews widened the road from Newport Way Northwest to the vicinity of Northwest Talus Drive and Southeast 82nd Street. Narrow shoulders bracketed the old, single-lane roadway.
The project added a sidewalk and a bike lane to the corridor as well. The widening project also included steps to improve fish passages through culverts at Tibbetts and Clay Pit creeks. Crews replaced broken culverts with modern passages lined with streambed gravel.
