The Merrimack River serves as the central artery for this cross-border region, flowing through a landscape defined by traditional New England crossroads and growing suburban corridors. In Nashua, the confluence of the Nashua River and Salmon Brook anchors the urban core, where educational and religious institutions like Rivier College and St Josephs Sch stand alongside the Boston and Maine railroad line. Southward, the map details the winding transition from Hillsborough County, New Hampshire, into the Middlesex County towns of Dunstable, Tyngsborough, and Chelmsford.
