Circumferential Highway (Nashua)

The Circumferential Highway is the commonly accepted name for a bypass route around the city of Nashua in southern New Hampshire, the majority of which has not yet been built. The purpose of the highway is to provide an alternate route for commuters to access the F.E. Everett Turnpike and U.S. Route 3 in Nashua. Most of the highway will be built in Hudson, with small sections also built through the towns of Litchfield and Merrimack as well as the city of Nashua.

Currently, the only segment to be built is a short 2-mile (3.2 km) interchange road between US 3, the Daniel Webster Highway, and N.H. Route 3A. This section utilizes the Sagamore Bridge, one of the two current bridges over the Merrimack River connecting Hudson to Nashua. The completed section begins at US 3, terminates at NH Route 3A to the east, and has a single interchange between its termini with the D.W. Highway before it crosses the river.

The Circumferential Highway has been planned since the 1950s, as the need for such a road has been apparent for a long time. To date, however, only a short 2-mile (3.2 km) segment has been built. One of the major provisions of the plan for the highway is to provide a new crossing over the Merrimack River. Currently there are four bridges over the Merrimack River between Lowell, Massachusetts and Manchester, New Hampshire. Drivers wishing to access U.S. Route 3 from the east side of the river have the following options (listed here from south to north):
