Rossville Boulevard begins at Walther Boulevard as a continuation of Putty Hill Avenue. It continues for approximately 4¾ miles to Essex, where it ends at a split. A left at this split would bring the motorist onto Stemmers Run Road, and a right onto Mace Avenue. Both these streets eventually lead to Eastern Avenue.
Rossville Boulevard, throughout its length, varies in number of traffic lanes from one to three in each direction. Some parts of the route have a median; others are divided simply by a double yellow line.
