New York State Route 952Q

New York State Route 952Q is an unsigned reference route designation for the portion of Walden Avenue outside of the Buffalo city limits in Erie County, New York, in the United States. The western terminus of the 14-mile route is at the Buffalo city line in Cheektowaga, where Walden Avenue continues west toward downtown Buffalo. Its eastern terminus is at Genesee Street in Alden, where NY 33 and Genesee Street continue on the linear northeasterly path followed by Walden Avenue for most of its routing.

Walden Avenue is the home of the Walden Galleria, a large shopping mall near the street's interchange with the New York State Thruway in Cheektowaga. As the road heads east through the towns of Cheektowaga, Lancaster, and Alden, it closely parallels the CSX Transportation-owned Rochester Subdivision rail line. NY 952Q, the longest non-parkway reference route in New York, was assigned in 1980 as part of a highway maintenance swap between the state of New York and Erie County.
