The southern portion of the long-anticipated Interstate 90 Undercrossing closes Tuesday morning as officials gather to cut the ribbon on the road link.
The undercrossing — Fourth Avenue Northwest — closes from 8-9 a.m. Tuesday near Northwest Gilman Boulevard and the Issaquah Post Office. Residents can join Mayor Ava Frisinger and other officials at the ceremony.
Parking for the ceremony is available near the intersection of Northwest Gilman Boulevard and Northwest Juniper Street just east of the red caboose, but space is limited.
Crews completed the road link between north and south Issaquah last month.
The undercrossing runs from a traffic signal at the post office, connects into the rail corridor behind Gilman Station, forms a T-shaped intersection at Southeast 62nd Street, continues along 221st Place Southeast and then terminates at Southeast 56th Street.
The undercrossing supplements traffic-clogged Front Street North and state Route 900, the other connectors between north and south Issaquah. Both older crossings also provide access to the interstate, but the combination of local traffic and vehicles from the on- and off-ramps add to the gridlock.
