During tunnel closures at the Baltimore Harbor Tunnel, drivers may experience 15-20 minute delays while two-way operations (during which one lane of southbound and northbound traffic is directed into the tunnel that remains open) are implemented. Closure times are dependent on traffic volumes.
The Northbound Tunnel is scheduled to be closed at 10:00 p.m. on the evening of Sunday, January 12, and at 8:30 p.m. on the evenings of Monday, January 13, through Thursday, January 16, for contractor operations. Two-way operations will be in the southbound tunnel. Re-opening is scheduled to take place at 4:30 a.m. the following morning.
This is a tentative schedule that is subject to change at any time due to weather, traffic conditions, emergency incidents, or priority closures.
