New York sits at the crossroads of the northeastern United States, where mountains, rivers and coastlines shape how the state meets its neighbors. From dense urban crossings downstate to quiet rural lines upstate, each border has a different character and set of connections.
There are 5 states that border new york, ranging from Connecticut to Vermont. For each one, the details are organized with Border type,Border length (km),Key crossings or border cities — you’ll find below.
How should I read the table of New York’s neighboring states?
Start with “Border type” to see whether the boundary is primarily land, river or lake; “Border length (km)” gives an approximate sense of how extensive the shared boundary is; and “Key crossings or border cities” highlights the major bridges, tunnels, highways or towns where travel and trade are concentrated. Use the three columns together to compare connectivity, geography and travel importance among the five states.
