A series of sites along the Washington–Rochambeau Revolutionary Route have been listed on the U.S. National Register of Historic Places or otherwise recognized and preserved. Buildings or roadway or other artifacts at these sites have been preserved and still evoke the army's passage in 1781 and its return in 1782. A multiple-property documentation study completed in 2001 addressed many of the Connecticut sites, and outlined criteria for NRHP-eligibility of others. Recognized historic sites include, from East to West:
March Route of Rochambeau's Army: Old Canterbury Road (41°41′22″N71°57′4″W / 41.68944°N 71.95111°W / 41.68944; -71.95111 (March route: Old Canterbury Road)) is a historic site in Plainfield, Connecticut, along the march route of Rochambeau's army. It includes a stretch of what is now Old Canterbury Road and a stretch of Canterbury Road (Connecticut Route 14A). It is a 2-acre (0.81 ha) site that was listed on the National Register of Historic Places in 2003. This particular segment of the route was deemed historically significant in 2002 "because it allows one to imagine the appearance of the Connecticut countryside--the cultivated fields, woods, stone walls, and narrow, windy roads--that the French army encountered as it made its way to and from the Battle of Yorktown, the engagement that decided the outcome of the American Revolution". It was traversed by Rochambeau's troops in June 1781 on their way to Virginia, and again in November 1782, on their return to Rhode Island. Part of the site is a "narrow, curving paved road", with a border of shrubs and vines and stone walls along much of its length. A stand of mature sugar maple trees gives shade to a portion of the site. Houses along the section are more modern than the 1781-1782 era, but are set back far enough so as not to interfere with the evocation of Rochambeau's marching troops. At the east end of the segment, stone walls are preserved on both sides of the road, and, as of 2002, "there are expansive views of plowed fields and pasture both to the north and to the south". The passage of the French army along this route is documented by period route map drawn by French military engineer Louis-Alexandre Berthier, republished by Rice and Brown in 1972 and reproduced in the 2002 NRHP nomination document.
Manship and Barstow Roads junction
Barstow Road to Westminster Road
March Route of Rochambeau's Army: Manship Road-Barstow Road (41°42′7″N72°0′13″W / 41.70194°N 72.00361°W / 41.70194; -72.00361 (March route: Manship Road-Barstow Road)) is part of the march route in Canterbury, Connecticut, that was listed on the National Register of Historic Places in 2003. It is significant as a preserved section of the march route which, in this area, is followed by what is now Connecticut Route 14. This section, however, is a bypassed loop of road, cut off by a road realignment in the 1930s, and therefore without traffic and not modernized. The section is approximately 1,400 feet of bypassed loop of road, on the north side of the main road, along Manship Road and Barstow Road, starting from a junction of the loop with Manship Road and running to Westminster Road. It is paved road about 20 feet wide, plus a margin to stone walls lining the road. The designated area is about 50 to 55 feet wide, extending to the walls. The National Register nomination of 2001 includes six photos of narrow roadway, stone walls, and the one house along this section. The house is itself historical, dating from about the 1840s, and adds rather than detracting from the historical feel. Rochambeau's troops marched through here in June 1781, and found the road along this general area to be the most difficult along their whole journey. Although the road has been paved, the visual appearance is still evocative of passage of troops.
March Route of Rochambeau's Army: Palmer Road (41°41′57″N72°3′47″W / 41.69917°N 72.06306°W / 41.69917; -72.06306 (March route: Palmer Road)) is the section of Palmer Road from the intersection with Miller Road east to a point 800 feet from the junction with Pudding Hill Road in Scotland, Connecticut. It was listed on the National Register of Historic Places in 2003. It was a narrow, steep, stony road then. Now, it has expansive views of farmland. The French troops, with artillery and wagons, reportedly found the marching difficult in this segment, though easier after the included hill. It was reportedly viewed by the French as "a narrow, steep, and stony road" in this segment (per Rice and Brown, 1972, p. 23, cited in NRHP document). The modern road is paved, but the hilly, winding nature of the road, and remnants of stone walls, and other elements evoke the experience of the French troops in this section.
