The Exit 11 ramp on I-295 southbound to the Falmouth Spur of the Maine Turnpike was closed because of a tractor-trailer rollover Thursday.

Traffic was backed up throughout the afternoon as crews removed a load of broccoli from the overturned truck, according to the Maine Department of Transportation.

Drivers were advised to the Portland exit near the Portland International Jetport to avoid the crash site, according to state police.

There was a significant traffic backup on the interstate in both directions, according to the department of transportation. Traffic is expected to continue to move slowly in the area for some time.
