ABSTRACT:
A sliding sign is movably mounted on an overhead truss which extends over a roadway. The sliding sign is mounted on rails connected to the top and bottom chords of the truss so that the sign may be moved from a position over the roadway to a position adjacent the shoulder of the roadway so that necessary maintenance may be performed on the sign without the need for lane closures of the roadway.
