Sometimes the result of roadwork may leave visible marks on the pavements. An example is the dowel bar retrofit process to reinforce concrete slabs in order to extend the life of older concrete pavements. The completion of the process leaves a symmetrical pattern of dash marks on the roadway, as if there were an associated meaning to the ...
Fire lanes in front of commercial buildings may have yellow paint to mark the fire lane. The curb should be painted yellow with the words “No Parking, Fire Lane” painted in black. On the pavement, yellow lines should be painted the width of the fire lane, with the words 12 inches (30cm) tall and painted in yellow.
In addition to marking the road edge, delineators are used to mark ramp gores, medians, and objects near the roadway such as fire hydrants. In such areas, the height of the delineators is established based on the typical amount of snowfall the area receives, ranging from 4 feet to more than 8 feet in height in areas with extreme snow depths.
In the Las Vegas area of southern Nevada, roads with multiple lanes use four pavement markers for each broken white line, a reflective marker followed by three Botts' dots. Botts' dots are used extensively in Hawaii. Most state-owned roads and many arterial roads in the state use Botts' dots as the delineation between lanes.

For bypasses, connecting roads, and parallel roads, the shield combines the "G" designation with a two-digit main line number, a type identifier, and a sequence number. Provincial expressways start with the letter "S". The main arteries and city bypass/connecting road shields display the "S" followed by up to two or two digits, respectively.
A station number written on a silt fence at a construction site. Linear referencing, also called linear reference system or linear referencing system (LRS), is a method of spatial referencing in engineering and construction, in which the locations of physical features along a linear element are described in terms of measurements from a fixed point, such as a milestone along a road.
