New York State Route 378
New York State Route 378 (NY 378) is a state highway in the Capital District of New York in the United States. It runs from Loudonville to Troy and traverses the Hudson River via the Menands Bridge. NY 378 once connected to Menands Road in the village of Menands; however, Menands Road has since been split in two by a now-closed exit ramp. NY 378 connects the western part of Menands Road with Troy. It also connects with NY 377 at Van Rensselaer Boulevard. NY 378 continues west of U.S. Route 9 (US 9) as Osborne Road (County Route 154). At its eastern terminus, NY 378 continues north as US 4. US 4 southbound is accessed by an eastward turn at the terminus.
Route description
NY 378 begins at an intersection with US 9 (Loudon Road) in the Loudonville section of Colonie as a continuation of County Route 154 (Osborne Road). NY 378 progresses southeast as Menand Road, a two-lane residential street through Colonie. The road expands to four lanes before intersecting with the northern terminus of NY 377 (Van Rennselaer Boulevard). After this intersection, NY 378 becomes a divided four-lane arterial, crossing eastbound through Colonie and into Menands. The route turns to the northeast, passing to the north of Ganser-Smith Memorial Park, crosses over a railroad line via a bridge, before entering into an interchange with NY 32 (Broadway). NY 378 becomes further divided into six lanes for a short distance after NY 32, entering interchange 7E and 7W of Interstate 787. NY 378 goes back to four lanes before crossing the Hudson River on the Menands Bridge, entering the city of Troy. Crossing over another railroad line on the other shore, NY 378 becomes known as High Street before curving northbound and terminating at an intersection with US 4 (Mill Street / Burden Avenue) in Troy.
