With design approval granted by the Federal Highway Administration, the New York State Department of Transportation can now proceed with the construction of planned improvements that will convert 3.2 miles of State Route 17 to Interstate 86 in the vicinity of Prospect Mountain in the city of Binghamton, Broome County. Plans include construction of the Prospect Street Interchange, six new bridges and an interchange at Exit 4 that will feature an innovative design. This project will now enter the final design stage. Preliminary work including installation of high mast lighting and Variable Message Signs (VMS) will begin in the fall of 2008. Significant construction in the area from Chenango Street west to the Binghamton City line is scheduled to begin in 2010.
