All traffic will be directed to the northbound tunnel.
Monday through Thursday between 7 p.m. and 11 a.m. motorists exiting the Lehigh Tunnel northbound, should be prepared for overnight intermittent lane closures when traveling between the tunnel and Mahoning Valley (Exit #74) Interchange because of additional maintenance.
