Beginning Sunday, drivers could legally drive 70 mph on the new U.S. 24 from Waterville to just west of Napoleon.
The new speed limits, effective yesterday, come following an overhaul of state highway speed limits.
The new speed limit applies to both cars and trucks, but in some cases the limits will remain the same for cars but increase for trucks.
In all, the limits on 607 miles of roadway statewide have been changed.
The General Assembly, after initially calling for the speed limit on rural Interstates to go from 65 mph to 70 mph, later ordered ODOT to look at so-called Interstate look-alikes — four-lane divided highways that are not part of the federal Interstate system and other roads to see where limits should be increased.
About 194 miles of rural divided highways will go to 60 mph statewide, 15 miles of rural expressways without traffic control signals will go to 65 mph, and 398 miles of rural freeways will go to 70 mph.
