The National Road and Zane’s Trace as it was in 1840
A 600 mile span stretched from Cumberland, MD to Vandalia, Ill. The construction began in 1811 and lasted until 1850 when Indiana completed its intrastate segment. The route from Pittsburgh ran west through Ohio, Indiana, and Illinois. It became the artery to move merchandise of all types. The route today can be found on parts of U.S. 40.
