Interstate 790 New York
Overview
Interstate 790 forms an L-shaped route between Downtown Utica and the New York Thruway (I-90) at Exit 31. The northern leg constitutes separate roadways running adjacent to I-90 from LeLand Avenue (NY 5) west to the NY 8/12 expressway along Horatio Street. A trumpet interchange connects this section of I-790 with the Thruway. It also doubles as NY 5, which dog legs south from Herkimer Road via LeLand Avenue.
The western branch of Interstate 790 accompanies NY 5-8-12 south from a directional cloverleaf interchange joining Horatio Street with NY 49. NY 49 extends the expressway west from I-790 to Rome while I-790 crosses the Erie Canal and Mohawk River into central Utica. Interstate 790 extends south to the Court Street off-ramp west of Downtown. NY 5-8-12 continue from that exchange along the North South Arterial Highway to New Hartford.
North-South Arterial
The $66.5 million North-South Arterial Project replaced the elevated section of NY 5, NY 8 and NY 12 through Utica. The largest project completed by the New York State Department of Transportation (NYSDOT) in the city of Utica extended the viaduct southward across Court Street, replacing a signalized intersection with a single point urban interchange (SPUI). The SPUI opened to traffic in June 2017.1
Completed on October 31, 2017, the project also improved the interchange joining I-790/NY 5-8-12 with NY 5A and NY 5S along Oriskany Street. A new off-ramp was added from NY 5A east to Lafayette and Varick Streets and existing ramps were reconfigured.1 The first of two contracts, including the March 2, 2014 implosion of the Fay Street Warehouse, started in March 2013. Work on the viaduct replacement and construction of the SPUI at Court Street started in March 2014.2

History
Designated as Interstate 590, the freeway spur into Utica was part of the proposed urban Interstate numerology submitted to the American Association of State Highway Officials (AASHO) by the New York State Department of Public Works on August 22, 1958. AASHO approved the numbering on November 11, 1958, along with the recommendations of changing the proposed I-190 in Buffalo to I-290, I-290 in Rochester to I-490, I-490 in Syracuse to I-690 and I-690 in Schenectady to I-890. However based upon that sequence in a letter sent to AASHO on December 4, 1958, New York requested that I-590 in Utica be renumbered to I-790
to keep the numerical order of loops and spurs in correct sequence
AASHO approved the proposed change on February 5, 1959. Coincidentally I-390 and I-590 were later assigned to routes in Rochester, keeping the numerical sequence from west to east intact. The establishment of Interstate 990 in 1980 resulted in an exception.
The Utica North-South Arterial was built in the 1960s to improve traffic flow through the city. The arterial between Court and Oswego Streets was constructed as an at-grade roadway with intersections due to community concerns with the elevated highway. The viaduct was rehabilitated in 1991.1
