Interstate 86

Interstate 86 is one of the nation's newest interstates. Commissioned in 1999, the interstate spends most of its mileage in New York along the Southern Tier Expressway (New York 17). Construction is progressing on upgrading all of New York 17 between New York 14 in Horseheads and Interstate 87 in Harriman to interstate standards. Full completion of Interstate 86 is scheduled to occur by 2009.

A separate Interstate 86 exists in Idaho, connecting Interstate 84 to Interstate 15. Since we have never been to Idaho, this is the only Interstate 86 page we have. However, if all goes according to plan, we will be driving Interstate 86 in Idaho during the Summer 2006 Roadtrip, so this page may be updated. This page will serve as a portal for both Interstate 86's.
