The Boyd-Roosevelt Highway

     In 1948 Panama issued a set of 5 stamps. Among them is a stamp with a map of the isthmus with the Canal Zone shaded and indicating the Carretera Boyd-Roosevelt. The “highway,” properly known as the Trans-Isthmian Highway, was provided for in the Hull-Alfaro Treaty signed in 1936. It connected Panama City and Colón and was built by U.S. troops during World War II. Apart from the Canal and the Highway no other details appear on the map.
