Binghamton is a major junction in the Interstate Highway System, much as it was during the days of the railroad. Interstate 81, a major north-south route, connects the city to Syracuse and Ontario, as well as to Pennsylvania and Appalachia. Binghamton is also the western terminus of Interstate 88, which gives a direct route to Albany. New York State Route 17, the Southern Tier Expressway, is being upgraded to Interstate 86, and spans the southern border of New York, providing access to New York City, as well as to the western Southern Tier and Erie, Pennsylvania. Between 1953 and 1966, the state built an arterial system to alleviate traffic, which includes the Brandywine Highway (New York State Route 7), North Shore Drive (New York State Route 363), and the portion of the Vestal Parkway (New York State Route 434) within city limits. Other major thoroughfares in the city include Chenango Street, Main Street (New York State Route 17C), and Court/Front Streets (U.S. Route 11).
