This project adds capacity for both directions of I-90 between Eastgate and West Lake Sammamish Parkway interchanges by restriping the roadway and adding an auxiliary lane. Crews are also building sound walls in strategic locations to minimize traffic noise.
What to expect
People who travel on both directions of I-90 should expect nighttime lane and ramp closures between 8 p.m. and 5 a.m. Also expect single lane closures during on Northwest Sammamish Road between 7 a.m. and 3:30 p.m. Lanes also may be narrowed and shifted in both directions of I-90.
