Situated on the western shore of the Hudson River, along the southern end of the New Jersey Palisades, and across from Midtown Manhattan, Weehawken is the location of the western terminus of the Lincoln Tunnel. According to the United States Census Bureau, the township has a total area of 1.5 square miles of which, 0.9 square miles of it is land and 0.7 square miles of it (43.71%) is water. As of the census of 2000, there were 13,501 people, 5,975 households, and 3,059 families residing in the township.
Though small, Weehawken is very urban, with a population density that is among the highest in the United States and comparable with that of nearby Jersey City. Weehawken is a residential community of primarily one- and two-family homes (many built during the Edwardian era) and low-rise apartment buildings.
Weehawken has a retail district along Park Avenue (its boundary with Union City) and large office and apartment/townhouse developments along the Hudson River. A few scattered retail shops and light manufacturing facilities blend into their respective neighborhoods. Local zoning laws prohibit the construction of high-rise buildings that would obstruct sight-lines from higher points in town.
