1 LON is the minimum length required to meet NCHRP 350 standards based on the number of sections used in the crash testing.

 

2 Pedestal feet required for TL-3 (62 mph) level.

 

3 Length was ballasted at each end with four unanchored 3.0m long PCMB equal, in weight, to 23 barrier sections.

 

4 Length was attached to an anchored crash cushion at one end and an anchored crash cushion base at the other end.

 

5 8 Anchors in each end section.

 

6 For TL-3 (62 mph) level four sections are to be added upstream from length of need.

 

7 Not on Approved Product List for Temporary Traffic Control Devices.

 

8 Minimum of 10 sections needed upstream from length of need for TL-3 level.
