What to expect

The construction of the auxiliary lane and soundwalls is complete. Some outstanding punch list items remain, so people who travel in the area may notice contractor crews working on I-90 or finishing landscaping on surface streets near the soundwalls.

Auxiliary lanes were added in both directions of I-90 between Eastgate and West Lake Sammamish Parkway, along with sounds walls at specific locations to reduce traffic noise.
