The southbound lanes were closed while troopers worked to clear a crash at Mile 21, Maine State Police tweeted shortly after 8 a.m. Police advised drivers to find alternate routes and rerouted cars off I-295 at Exit 22.

All lanes reopened to traffic around 9 a.m., but traffic remained backed up to Brunswick.

A separate crash was reported on the Maine Turnpike around the same time at Mile 48 south between Falmouth and Portland.
