Although it began in Youngstown and ended in Newstead as it does today, the initial routing of NY 93 deviated from the modern path in the vicinity of the city of Lockport.
The change removed NY 93 from Upper Mountain Road, a county-owned highway that had been part of the route since the 1930s.
The route proceeds eastward through the village as a two-lane road named Lockport Street, serving two blocks of commercial areas before bending to the northeast and passing into the residential eastern portion of Youngstown.
At the eastern village limits, NY 93 briefly widens to four lanes as it enters a partial cloverleaf interchange with the Niagara Scenic Parkway.
Another southeastward stretch brings the route across Twelvemile Creek and into the hamlet of Ransomville, where NY 93 becomes the community's main street.
Along the bypass, NY 93 briefly enters the city limits as it runs past several industrial facilities and intersects with Hinman Road (CR 903) just ahead of a bridge over the Erie Canal.
The Lockport Bypass ends here, leaving NY 93 to turn eastward onto Robinson Road.
The junction also marks a shift in the road's surroundings as the homes give way to open, rolling terrain.
[3] NY 93 takes over Akron Road's name and right-of-way, continuing eastward past a line of scattered homes to reach the sparsely developed hamlet of Dysinger.
Outside of Dysinger, NY 93 heads southeastward across undeveloped areas of Royalton, connecting to Block Church Road (CR 110) as it approaches Tonawanda Creek and the Niagara–Erie county line.
[3] Continuing southward, NY 93 runs across open, rolling terrain, meeting CR 259 (Tonawanda Creek Road) on its way to the hamlet of Swifts Mills.
Here, the rural surroundings briefly give way to residential areas as NY 93 intersects with CR 255 (Swift Mills Road) in the center of the community.
NY 93 runs past a line of homes before intersecting Cedar Street, a road maintained by Erie County as CR 261 north of the village.
The highway takes on the Mechanic Street name as it crosses over Murder Creek and leaves downtown Akron.
NY 93 exits Akron a short distance south of the junction, at which point the route heads into another area of open fields while retaining the Buell Street name.
[3] NY 93 was established as part of the 1930 renumbering of state highways in New York, connecting the cities and villages of Youngstown, Lockport, and Akron.
[25][26] The impetus for the change came from a resident of Upper Mountain Road, who demanded that trucks should be removed from the roadway.
