From 1935 to 1941, the Works Progress Administration made significant contributions to the nation’s defense efforts while providing much-needed Depression-era economic support to communities in the Monroe County area of Wisconsin. It constructed the Camp McCoy stone entrance gates along State Highways 16 and 21, with work beginning in 1940 and ending in 1941. The road connecting the two highways had existed since Camp McCoy opened for military training in 1909. The stone gates along Highway 16 cost $4,774 and were built with limestone, sandstone, and concrete walls set at a 45-degree angle to the main entrance road to Fort McCoy South Post; each wall consisted of 21 cement-capped limestone pillars and was approximately 250 feet long. Stone gates off Highway 21 at the Fort McCoy South Post entrance cost $760 and formed two limestone, sandstone, and concrete structures approximately 31 feet long and 18 feet wide, including the base. The South Post Stone Gates on State Highways 16 and 21 are the only remaining Works Progress Administration structures on Fort McCoy.
