The entirety of the roadway east of Bay Road in Webster is part of the Seaway Trail, a National Scenic Byway.

The section of Lake Road west of NY 250 remained state-maintained as an unsigned reference route for some time afterward; however, ownership of the roadway was transferred from the state of New York to Monroe County as part of a highway maintenance swap that took effect on November 26, 2007.

Lake Road begins at the eastern approach to the Irondequoit Bay Outlet Bridge in the town of Webster.

[4] The road continues along the lakeshore to the hamlet of Forest Lawn, a small community in northern Webster.

Past NY 250, Lake Road meets several local north–south roadways before crossing into Wayne County and the town of Ontario.

This intersection is the northern terminus of the county designation, with Lakeside Road continuing north as a town highway.

[4] In Williamson, the fields continue, this time to the south of the highway, as lakeside homes run along the northern side.

Inside the community, it intersects Hamilton Street[4] (CR 120)[6] at a junction that was once the northern terminus of NY 21.

It intersects North Geneva Road (CR 140) west of the village, then enters Sodus Point.

Under the terms of the act, it took effect 90 days after it was signed into law; thus, the maintenance swap officially took place on November 26, 2007.
