¶ Gibraltar Cable Barrier
¶ Summary
The Gibraltar barrier is a proprietary cable system. [1]
From the manufacturer's website:
The Gibraltar TL4 four cable High Tension Cable Barrier (HTCB) system is MASH16 approved on level terrain up to 4:1 slopes. This unique cable system design allows the top two cables to alternate within the top loop of the hair-pin which effectively slows and re-directs vehicles that leave the highway. The Gibraltar end terminal has also passed the rigorous and comprehensive MASH16 testing protocols. MASH16 requires a total of 16 crash tests which include heavier vehicles, more severe impact angles and higher impact speeds. Gibraltar’s cable system and end terminal successfully passed each of the required tests.[2]
¶ Identification
Key features of the Gibraltar system are:
