A single-vehicle roll-over crash on the Maine Turnpike in Wells closed one north-bound lane of traffic for more than an hour Monday afternoon.

The crash occurred near mile-marker 22 about 2 p.m. The right lane was closed while emergency personnel responded to the scene, said a dispatcher. It was reopen by about 4 p.m.

At least one person was ejected from the vehicle, but the extent of that person’s injuries was not immediately known.
