NY 840 opened to traffic in 2005, and the road was ceremoniously designated as the Officer Joseph D. Corr Memorial Highway in 2007.

Upon crossing into the town of New Hartford, NY 840 becomes a two-lane divided freeway and turns again to follow a more easterly routing.

[3] As NY 840 approaches the residential outskirts of Utica, it becomes a four-lane freeway and connects to Middle Settlement Road (CR 30) by way of a partial cloverleaf interchange.

East of the junction, the route curves southeastward and enters a major commercial district, where it intersects NY 5A by way of a single-point urban interchange.

[2] In April 2007, a bill was introduced in the New York State Senate that would ceremoniously designate NY 840 as the "Officer Joseph D. Corr Memorial Highway".

It was passed by both houses of the New York State Legislature and signed into law by Governor Eliot Spitzer on July 18, 2007.
