Thomas MacDonald "Forgotten" Road Man-- Part 1

Back on January 27th, I did an entry about a Shorpy photo of a man holding various old U.S. Highway signs (Jan. 21, 2014 Shorpy "Routes: 1925). The Shorpy site said the man's name wasn't given, but one of the people making comments said he thought the man was Thomas MacDonakld, chief and later commissioner of the Bureau of Public Roads and that much of today's interstate system (that would be the original U.S. highway system dating from the 1920s, not today's interstate system) and its standards are a result of his work in the early part of the 20th century. //// I had never heard of him and I am a big roadie. I have heard of Cyrus Abvery and Carl Fisher, but not Thomas MacDonald. //// Further investigation was needed. //// --RoadDog
