Interstate 684 (abbreviated I-684) is a 28.4 mile-long (45.7 km) north–south Interstate Highway in the states of New York and Connecticut. The highway connects Interstate 84 with Interstate 287 and the Hutchinson River Parkway, primarily serving commuter traffic to/from the northern suburbs of the New York metropolitan area. The route of the highway was originally designated as part of Interstate 87 during the 1960s. A section of the roadway first opened to traffic in October 1968. The final segment finished construction in December 1974.

[edit] Route description

Interstate 684 actually begins as two separate spur routes. The primary spur (the one officially designated I-684) begins at the White Plains/Harrison line at Exit 9A of the Cross-Westchester Expressway (Interstate 287). The other (designated New York State Reference Route 984J but still signed I-684) begins in Harrison, New York at exit 26A of the Hutchinson River Parkway and has one independent exit before joining with the I-287 spur into one route. The route follows a northerly course near the New York/Connecticut border, passing the Westchester County Airport, and at one point actually crossing the northwest corner of the Connecticut panhandle for 1.4 miles (2.3 km) without any exits before returning to New York (this brief interstate section is maintained by the New York State Department of Transportation but owned by the Connecticut Department of Transportation).

Towards the northern border of Westchester County, it meets the northern terminus of the Saw Mill River Parkway. The parkway runs along I-684 for a short distance between its interchange with I-684 and NY 35, where it ends. During this stretch, the Saw Mill Parkway serves as a collector/distributor road for I-684. Once crossing into Putnam County, I-684 interchanges with its parent Interstate 84 in Brewster^[3] before making a final interchange at a concurrency of U.S. Route 6, U.S. Route 202, and New York State Route 22, at which point the route terminates and becomes part of New York State Route 22. The speed limit is 65 mph (105 km/h), except on the spur from the Hutchinson River Parkway to just north of the Interstate 287 merge, and just south of the Interstate 84 terminus.

The route of the New York section of Interstate 684 is defined as part of Interstate Route 502 in New York Highway Law § 340-a.[1]

[edit] History

An expressway along the NY 22 corridor between White Plains and Brewster was planned by Westchester County in 1956. In 1961, the proposed routing of I-87 north of Elmsford along the east bank of the Hudson River was relocated to use the NY 22 corridor instead via modern I-287 and I-84. After much controversy, the routing of I-87 was approved by the Bureau of Public Roads in December 1964. Construction began soon after the approval with the southernmost section between White Plains and Armonk opened in October 1968. The northernmost section between Purdys and Brewster opened in 1969.

On January 1, 1970, I-87 was relocated to follow the New York State Thruway north of Elmsford. The old route was redesignated as I-684.^[2] Later that year, a third segment of the new highway between Armonk and Bedford Hills opened to traffic as well. The final segment, which proved to be difficult from an engineering standpoint, was completed in December 1974.
