The route starts as a four-lane divided highway in Brighton and western Penfield, and gradually narrows to a two-lane undivided road as it heads away from the city of Rochester.

[3] The portion of NY 441 from East Avenue to the Wayne County line is designated as the "Korean War Memorial Highway" by the state of New York.

[4] Linden Avenue separates from NY 441 roughly 0.4 miles (0.6 km) from I-490 and follows a routing parallel to NY 441 on the opposite side of the nearby Rochester Subdivision, a double-tracked rail line owned by CSX Transportation.

Continuing onward, Route 441 curves eastward and crosses over the CSX railroad line ahead of another intersection with Linden Avenue in the town of Pittsford.

[3] Although this portion of NY 441 is surrounded by woodlands, it is actually located in a largely developed area of Penfield known locally as Panorama.

[5] As NY 441 heads east through the town of Penfield, the businesses are largely replaced by residences.

In return, the county received a part of NY 21 in Williamson that connected to a state highway at only one end.

[8][9] Construction on a new divided highway through the towns of Brighton and Penfield began in the late 1960s and was completed by 1971, at which time it became a realignment of NY 441.

[10][11] While most of Linden Avenue was transferred to the state, the westernmost section from NY 96 to I-490 was maintained by Monroe County as part of CR 15.

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.
