The Boy Scouts of America completed the monumental task of simultaneously placing more than 3,000 LIncoln Highway Markers across the nation on September 1, 1928. The concrete markers were designed to immortalize the highway dream - and as a memorial to Abraham Lincoln. A careful plan required Scout troops along the route to carry out their part of the project upon an official signal from the Boy Scouts New York headquarters. These iconic markers were set from coast-to-coast in one day. Even troops in towns that were located miles from the highway volunteered their help.
