this is kind of scary
In July 2009, the westbound tube partially flooded after a
thunderstorm hit the Hampton Roads region. The flooding was caused by a failed water main, which burst and led a chamber below the tunnel roadway to fill with millions of gallons of water. Pumps designed to remove water from the chamber were overwhelmed, and water began to puddle on the roadway, forcing VDOT to close the tunnel for nearly seven hours during midday on July 2, 2009.

This closure forced hundreds of thousands of commuters, tourists, as well as Hampton Roads residents heading westbound for the
Fourth of July holiday, to divert and go through the MMMBT or the
James River Bridge, the only alternate routes to get to the
Peninsula. The MMMBT had troubles of its own during the afternoon, as a
pileup shut down the westbound lanes, closing the tunnel and causing a 20-mile
traffic jam[2] along
I-664. The James River Bridge was also closed on July 2 because of downed wires from the storm.
[3] The series of events involving all three water crossings led to a "
perfect storm" of traffic which led to
gridlock throughout all major arteries of Hampton Roads.
The flooding of the Hampton Roads Bridge–Tunnel caused widespread concern about
evacuation capabilities of the region during the approach of a
hurricane, as the HRBT, MMMBT and the James River Bridge serve as the primary
hurricane evacuation routes for residents of Virginia Beach, Portsmouth, Norfolk, and Chesapeake.
