Late night drivers should prepare for closures on Interstate 90 between 11 p.m. and 5 a.m. Tuesday, Wednesday and Thursday of this week.

· Tuesday, May 18 – Crews will close eastbound I-90 between I-5 and I-405 and detour traffic onto the I-90 express lanes. They will also close the ramps to eastbound I-90 from northbound I-5, Rainier Avenue S., Island Crest Way, E. Mercer Way, Bellevue Way and the eastbound I-90 transit lane.

· Wednesday, May 19 – Crews will close westbound I-90 at SE 37th Street and detour traffic onto SE Eastgate Way, west on Richards Road and back to westbound I-90.

· Thursday, May 20 – Crews will close eastbound I-90 at Richards Road and detour traffic onto Richards Road, SE 36th Street and to 150th Avenue to return to eastbound I-90. They will also close the ramps to eastbound I-90 from north and southbound I-405, Bellevue Way and the 142nd Place SE HOV ramp.

Drivers should also plan ahead for overnight closures on segments of westbound I-90 between I-405 and I-5 next week, Monday, May 24 – Thursday, May 27.

The closures will allow crews to lift into place a number of electronic sign bridges, a key part of the Washington State Department of Transportation’s Smarter Highways program.

Starting this summer, overhead electronic signs on northbound I-5 in south Seattle and on SR 520 between Seattle and Bellevue will alert drivers to reduce speeds or change lanes when there are collisions or backups on the road ahead. Crews will also activate the high-tech signs on I-90 between Seattle and Bellevue in spring 2011.

Washington is one of the first states to implement cutting-edge Smarter Highways technology that uses real-time traffic information to improve safety and reduce congestion.
