The '''Calhoun Street Extension''' is a series of roads in [[Trenton, New Jersey]], and nearby [[Lawrence Township, Mercer County, New Jersey|Lawrence Township]]. It runs from the [[Calhoun Street Bridge]] over the [[Delaware River]] to [[Brunswick Circle]], and is composed of the following named streets:
*'''Calhoun Street'''
*Part of Princeton Avenue
*'''Brunswick Circle Extension'''
The Extension was built as a joint undertaking by the [[New Jersey Department of Transportation|New Jersey State Highway Commission]], the city of [[Trenton, New Jersey|Trenton]] and [[Mercer County, New Jersey|Mercer County]]; it opened in January 1932. New roads built were the Brunswick Circle Extension and the northeast part of Calhoun Street; the rest of Calhoun Street and Princeton Avenue existed before the road was built. Princeton Avenue was already maintained by the county; the rest was taken over by the state.

The road was intended as a bypass of Downtown Trenton for cars and light trucks; the Calhoun Street Bridge had and still has a low weight limit. It may have been part of [[New Jersey Route 26|Route 26]], which continued north from Brunswick Circle. On the Pennsylvania side of the Delaware River, the road from the bridge rejoined the [[Lincoln Highway]] to [[Philadelphia]] at [[Fallsington, Pennsylvania|Fallsington]]. On the New Jersey side, the Lincoln Highway ran through Brunswick Circle, and the new Route 26 to [[New Brunswick, New Jersey|New Brunswick]], built in 1930, began at the Circle.

In the 1950s, it was numbered as part of [[County Route 583 (New Jersey)|County Route 583]] except along the Brunswick Circle Extension; it now has the following numbers:
*'''County Route 653''' along Calhoun Street
*County Route 583 and southbound [[U.S. Route 206]] (also signed as southbound [[U.S. Route 1 Business (Trenton, New Jersey)|U.S. Route 1 Business]]) along Princeton Avenue
*'''County Route 645''' (also signed as southbound US 206 and Business US 1; US 206 southbound officially stays with Princeton Avenue and Business US 1 southbound isn't officially there) along Brunswick Circle Extension.  
The Extension has been supplanted by [[U.S. Route 1 in New Jersey|U.S. Route 1]], which also connects Brunswick Circle to the Delaware River.
