In the triangle formed by Augusta, Charleston, and Savannah, Allendale is petty much in the center. Two major American ports, Charleston and Savannah are within two hours driving distance. In the 1950's and 60's, Route 301 was the main north-south corridor between New York and Florida, and Allendale prospered as a key stopping point along the way. Then in the 1970's, Route 95 was completed, and Walterboro took Allendale's place as a center for motels and restaurants. Still 301 is an excellent highway, and, along with other routes, such as 278 is an important trucking route.
