NY 363 is a short freeway that forms part of the Brandywine Highway (the remainder being part of NY 7). Constructed in 1968, the portion of the highway connecting NY 434 to NY 7 was initially not numbered and wasn't designated as NY 363 until 1981. Construction began in 2026 on a project to reconfigure the area around NY 434, eliminating the loop ramps and the section where northbound traffic is to the left of southbound traffic.
