Metuchen is a compact borough in Middlesex County completely surrounded by Edison Township. Known historically as the Brainy Borough, it developed around the railroad and retains a walkable downtown with shops, restaurants, offices, civic buildings, and cultural destinations. The NJ Transit station on the Northeast Corridor provides direct service toward New Brunswick, Newark, New York City, and Trenton. Route 27 runs through the borough, while nearby Interstate 287, the Garden State Parkway, and the New Jersey Turnpike provide regional highway access. Metuchen's residential areas include historic homes, tree-lined streets, multifamily buildings, and later suburban neighborhoods. Schools, parks, houses of worship, and community institutions are located throughout its small land area. The borough's independent municipal identity, active downtown, and strong rail connection distinguish it from the much larger Edison Township that surrounds it on every side.
