Sign posts are considered a "safety feature," so the procedure is identical to that of guardrail offset blocks as discussed in the previous section. To begin the process, contact the new products coordinator. etc. Examples include guardrails, bridge rails, median barriers, crash cushions, and breakaway supports for signs and light poles.

Temporary Precast Concrete Median Barriers: Established a policy that precluded the use of "permanent" concrete median barriers for traffic control and protection of work zones during construction operations. Only "temporary" concrete median barriers may be used for these applications. Superseded by Engineering Directive E E 8/9.

This reduction for a far side median cable barrier is 37%. Thus, a guardrail should be preferred over a concrete wall and a cable barrier should be preferred over a guardrail where the road and traffic conditions allow. In the light of the results, installing median cable barriers on both sides of the median to reduce their lateral offset is.

The ET-Plus™ energy absorbing end guardrail treatment is used as an impact head terminus on flexible barriers in the median or shoulder of a given highway.

The cable anchored system utilizes standard guardrail components with different post options. The ET Plus™ meets all NCHRP TL-2 and TL-3 criteria. Features. Our core product lines include guardrail, end terminals, cable and steel longitudinal barriers, crash cushions, truck and trailer mounted attenuators, water-filled barricades, sign supports, and delineators.
