'''Interstate&nbsp;787''' ('''I-787''') is an [[auxiliary Interstate Highway]] in the [[US state]] of [[New York (state)|New York]]. I-787 is the main highway for those traveling into and out of downtown [[Albany, New York|Albany]]. The southern terminus is, per New York traffic data, at [[New York State Thruway]] ([[Interstate 87 (New York)|I-87]]) exit&nbsp;23 southwest of downtown Albany. However, current signage indicates the terminus as along I-787's ramp to [[U.S. Route 9W in New York|US Route&nbsp;9W]] (US&nbsp;9W). The northern terminus of the route is unclear, with some sources placing the terminus at 8th Street in [[Troy, New York|Troy]], creating an overlap with [[New York State Route&nbsp;7]] (NY&nbsp;7) between [[Green Island, New York|Green Island]] and Troy. Other documents show I-787 as terminating at its interchange with NY&nbsp;7 and [[New York State Route 787|NY&nbsp;787]] in the town of [[Colonie, New York|Colonie]]. Regardless, the route is {{convert|10.16|mi|km}} long if extended to Troy, or {{convert|9.55|mi|km}} excluding the unsigned NY&nbsp;7 overlap.

North of NY&nbsp;7, I-787 continues north as NY&nbsp;787 to the city of [[Cohoes, New York|Cohoes]].
