Route 66

US 66 served as a primary route for those who migrated west, especially during the Dust Bowl of the 1930s, and the road supported the economies of the communities through which it passed. People doing business along the route became prosperous due to the growing popularity of the highway, and those same people later fought to keep the highway alive in the face of the growing threat of being bypassed by the new Interstate Highway System. Route 66 in Pulaski County begins/ends at Exit 169 - West on I-44. It continues throughout until the end/beginning of the county at Exit 145.
