Succasunna is Roxbury's population center and functional downtown — Main Street, the municipal and school campuses, Roxbury High School on Bryant Drive, and the Route 10 retail corridor.
It sits on the Succasunna plain, the flattest ground in the township. About 94% of homes are owner-occupied, and it has the highest median household income of any section.
Water here leaves by the Lamington River, which forms the community's southeast border and feeds the North Branch of the Raritan, and by Drakes Brook toward the South Branch.
