COLUMBUS -- The Ohio Department of Transportation has determined where in the state drivers will be allowed to legally go 70 mph on the highway.

A bill increasing the speed limit on certain sections of highway from 65 to 70 mph goes into effect on July 1.

Turnpike drivers are already permitted to travel 70 mph. Thirty-four other states, including Indiana, Michigan, Kentucky and West Virginia, already have posted 70 mph speed limits or higher.

The new 70 mph zones will encompass 570 miles out of 1,332 miles of interstate highways in Ohio.

Here are the areas where the speed limit will be increasing. (See attached PDF map. Note: New speed zones denoted in red.)
