502 Wide road (ISOM 2017-2)

Geometry: line


A maintained road wider than 5 m wide suitable for vehicles in all weather.

The width should be drawn to scale, but not smaller than the minimum width (0.3 + 2*0.14 mm – footprint 8.7 m). The outer boundary lines may be replaced with other black line symbols, such as symbol Fence (516), Impassable fence (518), Wall (513.1) or Impassable wall (515) if the feature is so close to the road edge that it cannot practically be shown as a separate symbol.
The space between the black lines is filled with brown (50%).
A road with two carriageways can be represented using two wide road symbols side by side, keeping only one of the road edges in the middle.


Colour: black, brown 50%.
