An accident near exit #159 in Newport is causing State Police to detour southbound traffic, til further notice.

UPDATE: State Police tell us the southbound lanes will reopen just before 10:30 this morning.

A State Police dispatcher told us the accident involves two tractor trailers, so it could be some time before traffic is flowing smoothly again. In the meantime, vehicles are being detoured at Exit #161 in Plymouth, around the crash site. Drivers might want to give themselves a little extra time on their morning commute, if they travel through that area.

We'll update this story as more details become available.
