When it actually enters Plattsburgh, it becomes first U.S. Avenue, then Peru Street when it passes the Old Catholic Cemetery. The Saranac River draws alongside twice before US 9 takes a left turn at Bridge Street and crosses it. Just past the bridge, the highway turns left again onto City Hall Place at the center of town. US 9 passes in front of the City Hall designed by John Russell Pope, also the builder of the Jefferson Memorial in Washington. Two more quick lefts follow past the large obelisk of Riverside Park, onto Miller and Cornelia streets, and then US 9 turns right at the eastern terminus of the lengthy NY 3 to follow Margaret Street north and out of the city.
