The Route 5-8-12 Arterial southbound lanes will be closed this Wednesday evening until Thursday morning while crews pour a bridge deck on the Oriskany Street bridge.

The Route 12 south ramp to downtown and 5s eastbound/Oriskany Street ramp between Schuyler Street and Cornelia will also be closed.

The DOT says crews should have all roads open by early Thursday morning.

Signed detours will be in place to divert drivers around the construction.
