Road maintenance depot

Road maintenance depots can range in size from small sheds storing just a few pieces of equipment, to vast buildings housing computer and closed-circuit television systems, allowing operators to monitor conditions across the road network.

[1] Other vehicles commonly kept at depots include lawnmowers, sprayers and road markers.

Along with garages, most depots also have either salt barns or brine tanks, to store de-icing agents for use in winter months, and filling stations to refuel vehicles, especially those that use red diesel, which is not available at public filling stations.

Larger depots have vehicle washes and repair shops to maintain the fleet, and a cafeteria and on-call room for workers.

These signs are also used to disguise sliproads leading to sensitive military institutions such as RAF Welford and to dissuade members of the public from using emergency evacuation routes and short cuts designed for emergency vehicles.
