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.
9 Unanchored deflection from MASH crash testing for TL-3. MASH testing standards and results supercede NCHRP 350 standards and results.
