What Is An LCD?
A Longitudinal Channelizing Barricade (LCD) is a federally-designated type of traffic roadway barrier. LCD’s are designed to provide visual guidance for motorists and pedestrians. They are meant to supplement drums when positive delineation is needed. They do not provide positive protection. An LCD fills the void in safety between the hazard that concrete barrier posses to motorists versus the gaps in lines of drums that allow vehicles and pedestrians into the work zone!
In order to be designated an LCD and be certified for use on a job site, a device must pass NCHRP-350 crash test requirements and the manufacturer must be issued a Federal Acceptance Letter (and be able to produce it on request).
Concrete Barriers? No Way!
Just remember, you don’t have to use a concrete jersey barrier in all construction zones! The (Roadside) Design Guide calls for concrete barriers to be used only under two circumstances: When it is less dangerous for vehicle occupants to impact the concrete barrier than to collide with a hazard behind the barrier, or to prevent an errant vehicle from penetrating a zone where workers are at risk. Deploying concrete barrier systems at work sites simply as a channelizing/delineating fence is poor practice and creates an unnecessary hazard in itself.
Safety and Benefits
- Much easier to set up than concrete.
- Requires no additional hardware or parts and forms an interlocking wall in any configuration.
- Due to their visibility and imposing nature, drivers respect these devices.
- Widely-spaced folding barricades, drums and cones are often confusing. LCD’s provide positive visual delineation by forming a wall.
- LCD’s keep drivers & pedestrians from shortcutting through construction zones.
- Other delineation devices are easily knocked over by traffic or weather, whereas water-filled barricades are stable.
- They positively delineate work zones at night and in bad weather.
