Roadside Obstacle Width
The REACT 350 ® II system with a Concrete Backup may be specified to protect obstacles up to
36” [914 mm] wide. The backup must be 30” [762 mm] to 36” [914 mm] wide to use standard side
anchor hardware.
Bidirectional Traffic
If bidirectional traffic (vehicles traveling opposite directions on either side of the system) is
present, special consideration needs to be taken when placing the system.
It is important for the highway design engineer and the assembler to ensure that the Concrete
Backup itself does not become a roadside obstacle to the reverse direction traffic. If the system
is placed in a location where traffic will be approaching from the rear of the system, the Backup
should not protrude beyond the obstacle being shielded. Concrete tapering may be required.
Also, an additional standard Side Anchor Plate should be rotated 180 degrees and placed behind
the first anchor plate (Figure 10). In this case, the backup must be at least 30” [762 mm] long.
