US 9

US 9 has two sections where it forms its own freeway; an extension of the Briarcliff-Peekskill Parkway known as the Croton Expressway, and a freeway section in Poughkeepsie. It also has a short freeway segment in Albany that was supposed to be part of the Mid-Crosswtown Arterial, a north-south expressway running from the I-787/Thruway junction to I-90. The Croton Expressway was once planned as an alignment of I-87 between I-287 and I-84; the designation I-487 was also considered, and the I-87 plans were cancelled when the section north of Peekskill was cancelled (the section south to Tarrytown was later cancelled as well).
