Bidirectional Sites
At bidirectional sites, the rear of the system must be either
offset away from the traffic approaching from rear of the
system or be installed with a Transition Panel to prevent
snagging of vehicles (see
Figure 45 on page 26 for maxi-
mum gap). The Transition Panels are depicted on page 9.
If attaching to portable concrete barrier (PCMB) the last sec-
tion of barrier must be anchored to the roadway (see Fig-
ure 4 and drawings supplied with your system). Anchor
Brackets are available from Energy Absorption Systems, Inc.
Note:
Walk-up inspections are recommended at least
once every six months for installations on asphalt.
