SR 534's path takes it through the western portions of Mahoning, Trumbull and Ashtabula Counties.

The NHS is a network of highways deemed most important for the nation's economy, mobility and defense.

It was originally routed along the majority of its current alignment, excepting a short stretch in northwestern Ashtabula County.

In that year, a new alignment of the state highway was constructed, bypassing the covered bridge to the east.

As a result, the former alignment that utilized the covered bridge to pass over the Grand River was turned over to Ashtabula County, and renamed as County Road 154 (CR 154).
