A century of modern highways. In honor of the Maryland State Roads Commission/State Highway Administration centennial (1908-2008), MPT partnered with SHA to produce Maryland Highway Centennial, a documentary on 100 years of modern roads in the state, to air late this fall. Progressing from simple mud roads in 1908 to the 17,000 lane miles of paved roads and 2,400 bridges of today, this is a major celebration of a milestone in transportation history. 87:44
