Interstate 90 Undercrossing

The long-planned Interstate 90 Undercrossing — a road link between north and south Issaquah — is due to open in December, about a month later than planners had estimated.

The delay came when the installation of bridge safety railings lasted longer than expected.

City Public Works Engineering Director Bob Brock said the entire connector could open by the week of Dec. 6 if no construction problems arise. The city planned open Southeast 62nd Street and 221st Place Southeast — streets closed during construction — Nov. 24.

The roadway runs from a traffic signal at the post office along Northwest Gilman Boulevard, forms a T-shaped intersection at Southeast 62nd Street, continues along 221st Place Southeast and then terminates at Southeast 56th Street.

The project also included another entrance to Gilman Village from Northwest Gilman Boulevard and another entrance for the post office.

The undercrossing fits into the street grid as Fourth Avenue Northwest. The initial phase is open from Northwest Gilman Boulevard to the post office entrance.

The project is designed to alleviate traffic congestion on Northwest Gilman Boulevard and Front Street North.

City Council members approved a $2.4 million budget for the project; more than $1.8 million has been spent so far.

The council picked Kirkland-based MidMountain Contractors to build most of the road link from the post office traffic signal along Northwest Gilman Boulevard to Southeast 56th Street. Issaquah-based Seacon agreed to construct another piece of the undercrossing in order to build the Issaquah Medical Building on the former Zetec site.
