It begins at an intersection with U.S. Route 4 (US 4) just south of Troy and ends at a junction with NY 150 in the hamlet of Wynantskill.

NY 136 provides access to Hudson Valley Community College, located in an otherwise residential area of suburban Troy.

Here, NY 136 also connects to County Route 76 (CR 76, named Glenmore Road), which provides access to the headquarters for the 42nd Infantry (Rainbow) Division of the New York Army National Guard.

The route heads eastward as Williams Road, intersecting with CR 65 (Bloomingrove Drive) as it passes south of La Salle Institute and Hudson Valley Community College.

[5] The junction between NY 136 and Winter Street Extension has since been reconfigured to directly connect Williams and Whiteview Roads.
