Because Cleveland's main roads were built to lead to and from downtown, it's hard to drive, say, from Lakewood to Middleburg Heights. But there is a way to make the north-south trek less frustrating. Valley Parkway gives drivers a beautiful route past the aggravation. It meanders from Lakewood to Strongsville along the Rocky River, through stands of willow and cottonwood trees and past shale cliffs rising 90 feet from the road. The most amazing sights along the drive may be man-made: the magnificent bridges arching across the valley.
