The New Deal administrations created to fight the Great Depression of the 1930s provided the manpower for the Bureau's first effort; workers from the Works Progress Administration produced steel signs for locations across the state, but their intentionally temporary nature meant that many had greatly deteriorated by the time that they were removed for scrap during World War II.[1] After the war's end, state officials began to plan for a system of aluminum markers that could be expected to endure indefinitely.The state made its first substantial foray into the program in 1966 as it reached the sesquicentenary of statehood, and the Sesquicentennial Commission quickly doubled the number of state-financed markers.However, permanent financial involvement only began in 1989, when substantial funding was first granted for the purchase of markers on a long-term basis.These counts are based on entries in the Indiana Historical Bureau's marker list as of March 2024.
