A barrier system constructed of modules which includes a frame, a concrete foundation, a frame attached to the concrete foundation and supporting a non-vertical front side plate and a vertical rear side plate so that the front side plate and rear side plate meet at the top and are spread apart from each other at the bottom, slotted connectors on the front side and connectors on the rear side, the module adapted to be joined to an adjacent module either at the same elevation or a different elevation. The modules are joined together via bolts in the rear side connectors and threaded toggle bolts and drop toggle nuts through the front side slotted connectors. Extenders within the slots of the open ended connectors are used when connecting adjacent modules at different elevations to accommodate for slotted connectors of different sizes which must be connected to each other.

Systems and methods for the continuous slip form construction of concrete barriers over support cages. A tube feeder of a slip form construction system can include angled tubes that can direct reinforcing bars into a concrete barrier and also provide space between the tubes for insertion of a support cage through the system and into the concrete barrier.

A roadside barrier which has underlying concrete support blocks, a mesh fence, optionally including overlying transparent sheet material, which is erected on the blocks, and a deterrent, sloping mesh-material, surface, which hinders human access, at a base of the fence on the support blocks.

A safety barrier includes: a body installed on a road; a steel plate portion placed between the body and the road; and an anchor portion passing through the steel plate portion and having an upper part buried in the body and a lower part buried in the road, wherein a first space in which a middle part of the anchor portion other than the upper part and the lower part is placed, is formed between the body and the road, and when an impact is applied to the body, the body is moved while accompanying bending deformation of the middle part in the first space so that the impact is absorbed, and after bending deformation of the middle part occurs, the steel plate portion breaks the anchor portion to implement further movement of the body caused by the impact so that the impact is dispersed.

An anchorless crash cushion apparatus having a plurality of interconnected water-filled crash cushion elements and a non-water filled forward-most cushion element includes vehicle capture structure resisting upward tilting of a frontally impacting vehicle and ramping of the frontally impacting vehicle and stabilizing structure resisting relative rotation between the crash cushion elements in both vertical and lateral planes during vehicle impact. External elongated deformable structural members extend along the sides of the crash cushion elements and bend outwardly away from the crash cushion elements during frontal vehicle impact.

The present subject matter provides a telescopic Jersey barrier, configured to easily and rapidly lengthen and shorten. The telescopic Jersey barrier includes multiple barrier units configured to be inserted one into the other. Additional embodiments of the telescopic Jersey barrier are described herein.

A roadway safety device includes one or more spacers which engage a falling arm attached to a sign so as to lift the sign relative to a structure on which a housing bracket attached to the arm rests. The roadway safety device may include a spacer which dampens the fall of the arm and which holds the arm at an upward angle to make the sign more visible to drivers.

A modular cover panel including two or more cover panels that cover a parapet or barrier along a roadway. Multiple cover segments may overlap one another to form the modular cover panel and each cover panel is individually hung or suspended by brackets affixed to the parapet. Each cover segment has one more surfaces intersecting with other to cover the parapet and a top surface that overhangs a top surface of the parapet. A cable may be disposed through a slot of a hanging bracket and a pin may secure the cable thereby providing a mechanical attachment to the assembly.

The present invention relates to a friction-increasing element for attachment to a roadblock, comprising a friction-increasing element body for attachment to the roadblock, and at least one tapered contact edge, which tapered contact edge is carried by the friction-increasing element body such that the tapered contact edge is facing away from the friction-increasing element body. The invention also relates to a roadblock provided with a least one of such friction-increasing element.
