A cable-stayed bridge has one or more towers, from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly.
Interstate 475 (I-475) is an auxiliary Interstate Highway in Ohio that is a 20.37-mile (32.78 km) western bypass of Toledo. The southern terminus is I-75 exit 192 near Perrysburg. From the southern terminus to exit 14, I-475 is cosigned with US Route 23 (US 23) and is signed the north–south section of I-475. From exit 14 to the eastern (northernmost) terminus at I-75 exit 204 in central Toledo, it is signed the east–west section of I-475.
Interstate 280 (I-280) is a 12.41-mile-long (19.97 km) auxiliary Interstate Highway in Ohio that connects I-75 in northeast Toledo with I-80/I-90 southeast of the city in northeastern Wood County. Built between 1955 and 1959, the route was originally part of the Detroit–Toledo Expressway. Although first designated in 1959, the highway originally contained several at-grade intersections and other features which left it substandard to the Interstate Highway System until 1990. Further construction in 2007 built a new crossing of the Maumee River, replacing an outdated drawbridge. The highway serves as an easterly bypass of the Toledo metropolitan area, passing through the communities of Northwood and Oregon. It is one of two auxiliary Interstate Highways serving Toledo, the other being I-475.

An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons deviating upward from the deck. In this concept, they remain part of the main bridge superstructure.
