Old Hardin Highway - Lockwood MT "Practically every two-lane highway in Eastern Montana was built with the help of WPA funds, said Jon Axline, a historian with Montana's Department of Transportation.
A prime example around Billings is the Old Hardin Highway, which was improved in the 1930s, Axline said. The road climbs out of Lockwood, clinging to the hillside in a series of tight curves.
In the 1930s, roads were built to fit the landscape. The interstate highway took the opposite approach, molding the landscape to fit the road's design."
