NY 17, as of 2012, was the longest route in New York, with the freeway sections composed of the Southern Tier Expressway and the Quickway. The freeway starts at I-90 in Pennsylvania and ends at the Thruway in Harriman; NY 17 once ran from Westfield to its present terminus at the New Jersey state border. The freeway is in the process of being upgraded to I-86; signs are currently posted for I-86 on a couple segments, and regions 5 and 6 are phasing out the NY 17 signs. It is believed that NY 17 will be truncated to Harriman when the I-86 is completed. What is now I-86 in Pennsylvania was once PA 17, which was a duplicate route number.

Spur Route
The Sourthern Tier Expressway has a short spur in Bemus Point connecting from exit 10 to NY 430. It appears to be a remnanent of a longer spur that might have been planned to serve Mayville and Westfield. Some speculate that it may have been planned to be part of a former routing of the Southern Tier Expressway, and the reference route (954J) carries reference markers marked 17.
