The entry to the Issaquah Post Office from the future Interstate 90 Undercrossing has closed for five weeks as crews build the north-south connector.
The post office can instead be accessed from a new driveway connected to Northwest Gilman Boulevard.
During the closure, crews plan to widen the road and add utilities. Work on lighting and traffic signals should continue as well. Poles for traffic signals could be installed as early as next week.
On the opposite side of the interstate, Southeast 62nd Street from East Lake Sammamish Parkway to the 600 block of 221st Place Southeast remains closed as crews construct a bridge. Plans call for utilities to be installed next week.
The completed roadway will run from the traffic signal at the post office along Northwest Gilman Boulevard, form a T-shaped intersection at Southeast 62nd Street, continue along 221st Place Southeast and then end at Southeast 56th Street.
Crews should complete the road by early fall. The cost to plan and build the connector has reached about $3 million.
The city estimates the undercrossing could remove 2,000 to 4,000 vehicles from Northwest Gilman Boulevard and 3,000 to 6,000 vehicles from Front Street North each day. Gilman Boulevard handles 29,000 cars per day; Front Street handles 49,000.
