Interstate 90 Undercrossing construction progresses

NEW — 6 a.m. Oct. 15, 2010
Construction continues on the Interstate 90 Undercrossing, or Fourth Avenue Northwest, a north-south link beneath the interstate.
The contractor has paved several phases of the project. Though the new signal at Northwest Gilman Boulevard and Fourth Avenue Northwest is operational, the entrance to the Issaquah Post Office off of the undercrossing is not yet available for use, in order to keep the job site safe. In the meantime, drivers must continue to use the driveway just west of the new signal.
The long-planned undercrossing should be completed by next month. The project is designed to reduce traffic on Gilman Boulevard and Front Street North.
