A cement truck rollover has forced the closure of an offramp to Interstate I-295’s northbound lanes in South Portland on Wednesday, WMTW reported.

The crash happened around 9:30 a.m. on Ramp A, which connects the Maine Turnpike approach to I-295. Another report, from News Center Maine, indicated that a tractor trailer truck was also involved in the crash.

The closure is expected to last for several hours as rescue workers attend to the scene.
