At a length of 234 miles (377 km), it is the third longest state route in Ohio.

Since 2017, the southern terminus of SR 93 has been at the Kentucky state line on the Oakley C. Collins Memorial Bridge over the Ohio River.

It travels through downtown Ironton on South Second Street and Park Avenue unsigned.

After Wellston, SR 93 returns on its northerly route to Hamden, McArthur, Logan, New Lexington, Crooksville, and Zanesville.

From this point to its northern terminus, it is a road in which traffic jams are expected during rush hour.
