The Midtown Tunnel is now open following a six vehicle crash earlier in the day. However, major delays are expected.
The off ramp from the Midtown Tunnel to Brambleton Avenue East was also temporarily closed due to high water but has since been reopened.
Downtown Tunnel traffic is also heavy with a 1 mile backup westbound.
According to a tweet from the Suffolk Department of Works, crews have closed North Main Street at the Kimberly Bridge. They say water is now covering all four lanes. Crews will remain on the scene until the tide recedes.
