FREMONT, Ohio – A crash on the Ohio Turnpike has blocked the westbound lanes of the roadway and caused a traffic backup for several miles.

A State Highway Patrol dispatcher said the crash was reported around 10:30 a.m.

The Ohio Turnpike Commission said the growing traffic jam spanned about four miles shortly before noon.
