Lay By Design Services



A lay by or rest area is an area adjacent is a public facility, located adjacent to a large thoroughfare such as a highway or motorway at which drivers and passengers can rest, eat, or refuel without exiting on to secondary roads.

The size of the lay by is determined by the maximum speed permitted on the highway and the size of the vehicles that use it.


What is involved in Lay by design?

A lay by design is laid out geometrically, satisfying the road design requirements set by the relevant state or local government authority. Key elements of a good lay by design include:

  • appropriate transition lengths to enable the vehicle to safely reduce its speed
  • lane width and tapering length required for the vehicle to pick up speed before it joins the highway
  • an appropriate drainage solution, allowing for the longitudinal and transverse fall of the existing or the new road where the new layout is to be placed
