Abstract
A safety end barrier for use in coordination with roadside barriers. The safety end barrier lies substantially parallel to the direction of traffic flow and increases in height from about natural ground level at its lower end. The end barrier has sidewalls which angle upwardly outward from the barrier base. The taller end of the end barrier is preferably connected to a concrete roadside barrier through apertures extending from a recessed trough to the end of the safety end barrier. Preferably, bolts with two threaded ends, insertable through the apertures and secured by corresponding nuts, are used as connecting devices to connect the end barrier to a concrete roadside barrier.
Claims20
A safety end treatment barrier for use alongside a traffic lane, which comprises:
- an elongated concrete member which increases to a height of between about 12 and about 24 inches along its length and in the same direction as the flow of traffic alongside the member;
- said member including a base, and a sidewall facing the traffic lane which slants outwardly from the base.
A safety end treatment barrier for use alongside a traffic lane, which comprises:
- an elongated concrete member which:
- (a) increases in height along its length from a traffic upstream height sufficient to render the member durable but low enough to clear below vehicles to a downstream height of between about 12 and about 24 inches;
- (b) increases in width along its length from a traffic upstream width sufficient to render the member durable but less than the lateral distance between the wheels of a vehicle a downstream width of between about 20 and about 30 inches;
- and
- (c) has a sidewall facing a traffic lane which plants upwardly and outwardly at an angle between about 60 and about 89 degrees relative to transverse a six of the member.
