LYNNFIELD (CBS) – A giant pothole on Route 1 in Lynnfield left 20-to-30 vehicles damaged Thursday morning, according to Massachusetts State Police.

Troopers shut down one lane of Route 1 south just before the Lynnfield Tunnel after the cars started getting flat tires and other damage during the morning rush hour.

The pothole they hit is about four feet wide.

“This destroyed two of my wheels, completely destroyed at 5:30 in the morning,” driver Nick Nelson told WBZ-TV on Facebook.

“We could not see the pothole in the dark until a split second before impact. This made for a pretty terrifying (and expensive!) morning commute,” Julie Will commented on Facebook.

MassDOT said Thursday afternoon that all repairs to the pothole are finished and that all lanes are open.
