Travel directions
I-74 west of Cincinnati.
I-74/I-275 west of Cincinnati.
At Harrison, the highway enters the state from Indiana. Interstate 74 in Indiana comes from Indianapolis. The highway has 2×2 lanes here. One passes through wooded and hilly area, and at the hamlet of Blue Jay joins Interstate 275, this is the Cincinnati ring road. Both roads were then double numbered with 2×3 lanes. A few miles down the road, at Taylors Creek, the roads split again. I-74 then runs through the western suburbs with 2×2 lanes. These get denser, and just before I-75 the road widens to 2×3 lanes. In northwest Cincinnati, the road ends at Interstate 75, the highway from Cincinnati to Dayton, Toledo and Detroit.

The West Huntington Bridge, also called the West End Bridge is a truss bridge in the United States, located on the border of the states of Ohio and West Virginia. The bridge spans the Ohio River near Huntington, West Virginia.
Characteristics
The West Huntington Bridge is a steel truss bridge with a total length of 686 meters and a main span of 171 meters. The bridge deck is 8.5 meters wide and has two lanes off US 52. The bridge connects on the Ohio side with the Ironton to Chesapeake expressway, and on the West Virginia side with a grade separated connection to Interstate 64. The bridge is therefore a connection between two high-quality roads. It is the westernmost bridge for road traffic over the Ohio River in West Virginia. The bridge is toll-free.
History
Originally, US 52 crossed the Robert C. Byrd Bridge near downtown Huntington. In the 1960s, Interstate 64 was built in West Virginia, and it was deemed necessary to connect US 52 in Ohio and Interstate 64 in West Virginia on the west side of Huntington town. This bridge opened to traffic in 1968. However, the bridge was unusually narrow for the time, with only two lanes of traffic.
Traffic intensities
Every day, 23,200 vehicles cross the bridge, which is subject to a maximum load.

The Williamstown Bridge is a truss bridge in the United States, located on the border of the states of Ohio and West Virginia. The bridge spans the Ohio River between Williamstown, WV and Marietta, OH.
Characteristics
The bridge is a steel truss bridge with a total length of 797 meters. The bridge has two large spans, the northern span is 198 meters long, the southern span is approximately 181 meters. The truss construction makes these spans possible. In addition, there are bridges on both sides. The bridge is single lane, with one lane in each direction. Over the bridge runs State Route 31 in West Virginia and State Route 60 in Ohio. Williamstown, West Virginia is south of the bridge. Greater Marietta, Ohio is on the north side. About a mile upstream, the Marietta-Williamstown Interstate Bridge spans the Ohio River. The Williamstown Bridge is therefore mainly of local importance.
History
In 1903, the first bridge was built on this site, a steel cantilever bridge. This was the first inland cantilever bridge for vehicular traffic in the United States. It handled through traffic until the Marietta-Williamstown Interstate Bridge of Interstate 77 was completed in 1967. The bridge was replaced in 1992 by the current truss bridge.
