2008-style state highway marker on eastbound LA 1064 in Natalbany.
After months of posting the black-and-white shields without a line border, La DOTD began posting some state shields with a white border, as in this photo taken on January 14, 2010. This marker is located on LA 21 between Covington and I-12.
