The National Road, commonly known as US 40, is undoubtedly one of Indiana's most historic transportation routes.
Construction on the road began in 1828, and it played an integral role in shaping the history of the Hoosier State. Spanning through the heart of the state, Indiana's National Road has seen changes through the years--some for better, some for worse. Though interstate travel has somewhat made US 40 the road less traveled, Indiana's National Road remains a treasured landmark, embraced by those who appreciate and understand its historical significance. Dilapidated buildings and closed signs are common sites but do not overshadow the thriving communities of Cumberland, Centerville, and Cambridge City and other small towns along the route. The cities of Indianapolis, Terre Haute, and Richmond continue to develop while leaving the historical aspects of US 40 intact.
