Late night drivers using I-90 on the eastside should be prepared for intermittent ramp and lane closures this week.

Crews are continuing their work building foundations for sign bridges that will become a part of the smarter highways system for I-90.

Starting at 7 p.m., Monday, each weeknight until 5 a.m. the following morning, crews may close up to two lanes on east or westbound I-90 between Mercer Island and Bellevue. Crews also plan intermittent closures on the following ramps each night:

• 142nd Place SE to westbound I-90 direct access ramp

• Eastbound I-90 to Bellevue Way

• Bellevue Way to westbound I-90

• Eastbound I-90 to 148th Avenue

The new sign bridges will hold overhead electronic signs alerting drivers to reduce their speed or change lanes when there are collisions or backups on the road.

There will also be roadwork, and some delays, on I-405 this week.
