the highway initially serves three blocks of homes before entering a linear commercial district at a junction with 12th avenue. from here, the road crosses a canadian pacific railway line as it approaches downtown watervliet, where state maintenance resumes one block west of an intersection with ny 32 (second avenue). past ny 32, ny 2 crosses over i-787 and the hudson river on the congress street bridge, which links watervliet to the city of troy on the opposite bank. just east of the bridge, the route enters a partial interchange with front street and splits into a one-way pair along congress street (westbound) and ferry street (eastbound), both two lanes wide. the couplet takes the route through the central troy historic district, where ny 2 eastbound heads into a two-block tunnel that carries the highway underneath the campus of russell sage college.
