State Barrier Pin Standards

Interactive map requires browser support for SVG. See state list below.

Highway barrier pins are used in two ways: to connect concrete barrier sections together, or to anchor concrete barriers to the ground. Highway barrier hardware can sometimes be confusing to the individual who is not well versed in the terminology, as the name of a particular type of connection bolt can vary depending upon the application and the agency that is specifying its use.

Mouse over the interactive map above to see more information on the various styles of connecting pins and anchor pins by state, or choose your state from the list below:

Connecting Pins


Bolts used to connect concrete barrier sections together can come in many shapes and forms but they typically share a common design element for ease of installation and removal. This can be in the form of a lifting ring on the top side, a forged head, or a welded washer. They may be used with precast concrete barrier, concrete barrier rails, temporary barriers, moveable barriers, and other types of barrier. This type of barrier connection hardware may be referred to as connecting pins, connecting bolts, connecting rods, barrier pins, or barrier rods.

Anchor Pins


Bolts or rods used to immobilize or anchor concrete barriers in place can be headed bolts or non-headed rods and can be driven it at an angle or perpendicular to the face of the barrier. Many designs offer an optional beveled end or angled point for ease of driving the rods or bolt into the ground or asphalt. This type of barrier hardware may be referred to as anchor bolts, anchor pins, anchor rods, base pins, base rods, stabilization pins, stabilization rods, or stabilization bolts (to name a few).
