Prepare for nighttime closures of the Interstate 90 exit to West Lake Sammamish Parkway Southeast.
The eastbound I-90 off-ramp to West Lake Sammamish Parkway will close from 9 p.m.-5 a.m. Sept. 24 and Sept. 25, 2013, for paving work on a new roundabout. A signed detour will be in place during the closures.
Crews are also building the new curbs and traffic islands to guide drivers through the roundabout.
The Washington State Department of Transportation expects the roundabout to be completed in October.
