East Hanover Township is located in eastern Morris County between Hanover Township, Florham Park, Livingston, Roseland, and Parsippany-Troy Hills. Route 10 is the main commercial corridor, while nearby Interstate 280, Route 24, and Interstate 287 provide access toward Morristown, Newark, and the wider metropolitan area. The township contains established residential neighborhoods, corporate and industrial properties, shopping centers, schools, parks, houses of worship, and municipal facilities. The Passaic and Whippany river systems influence lower areas and parts of the local boundary. East Hanover developed from farms and rural settlements into a major suburban employment and retail center during the twentieth century. Commercial activity is concentrated along Route 10, while quieter residential streets extend north and south of the corridor. The township's location near the Morris-Essex county line creates strong ties to both regions and gives it a central position among northern New Jersey's office and commercial districts.
