Standing at 42 inches (107 cm), it is 10 inches (25 cm) taller than the standard Jersey barrier. Ontario's Ministry of Transportation has been replacing guiderails (steel guardrail and steel box-beam) with these tall wall barriers on 400-series highways since the early 1990s, while the City of Toronto is doing likewise on portions of the ...
Traffic barrier with a pedestrian guardrail behind it. Traffic barriers (known in North America as guardrails or guard rails, [1] in Britain as crash barriers, [2] and in auto racing as Armco barriers [3]) keep vehicles within their roadway and prevent them from colliding with dangerous obstacles such as boulders, sign supports, trees, bridge abutments, buildings, walls, and large storm drains ...
Guardrail protecting expensive machinery. The majority of safety guardrails used in industrial workplaces are made from fabricated steel. Steel guardrail was originally developed by Armco (The American Rolling Mill Company) in 1933 as highway guardrail but is often used in the factories and warehouses of the industrial sector, despite not being intended for this application.

Minimum lane width: The minimum lane width is 12 feet (3.7 m), identical to most US and state highways. Shoulder width: The minimum width of the left paved shoulder is 4 feet (1.2 m), and of the right paved shoulder 10 feet (3.0 m). With three or more lanes in each direction, both shoulders are to be at least 10 feet (3.0 m) wide.
Cable barrier. A cable barrier, sometimes referred to as guard cable or wire rope safety barrier (WRSB), is a type of roadside or median safety traffic barrier / guard rail. It consists of steel wire ropes mounted on weak posts. As is the case with any roadside barrier, its primary purpose is to prevent a vehicle from leaving the traveled way ...

The Manual on Uniform Traffic Control Devices for Streets and Highways (usually referred to as the Manual on Uniform Traffic Control Devices, abbreviated MUTCD) is a document issued by the Federal Highway Administration (FHWA) of the United States Department of Transportation (USDOT) to specify the standards by which traffic signs, road surface markings, and signals are designed, installed ...
There is no legal distinction between a guide rail and a guard rail. According to the US Federal Highway Administration, the terms guardrail and guiderail are synonymous. [5] Several types of roadway guide rail exist; all are engineered to guide vehicular traffic on roads or bridges. Such systems include W-beam, box beam, cable, and concrete ...
