* Beyond north end of I-376
** It's a large diversion to Macedonia, OH. Owners traveling I-80 with longer range cars will be able to skip it. Would be a nice problem to solve. Maybe Richfield, OH? Not too much and could be busy due to being so close to Cuyahoga Falls area. There's also a couple of hotels (Clarion much the better of the two) in Boston Heights, OH that would divert much less. Nothing else near them though.
^ Diversion due to construction; due to end September 2017.
