Ohio follows the general guidelines for road types and road names of the USA.
It is served by eight primary (I-70, I-71, I-74, I-75, I-76, I-77, I-80 and I-90) and fifteen auxiliary Interstate highways, as well as numerous US, state, county and township routes. The longest numbered highway in Ohio is SR-7, followed by US-62, US-20, SR-3 and I-71. The only toll road in Ohio is the Ohio Turnpike, which follows portions of I-90, I-80 and I-76 from Indiana to Pennsylvania. Ohio is the only US state that has numbered township routes in Waze. See the highway names table for further guidance on the naming of numbered highways in Ohio.
Locking standard
The following defines a set of minimum locking standards proposed for all roads within Ohio. Any road of a certain type or category must be locked at least to the level in the chart below. Roads may be locked higher for protection and special situations (tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.
It is understood that more rural or inactive areas may not yet meet this standard: editors are encouraged to recruit and mentor additional editors to build coverage.
A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US Road Type Standards.
