These plans show types of bollards used on roadways.
Bollard Type 3 (RD-14)
The Type 3 Bollard is used at the entrance of a pedestrian and bicycle paths to prevent motor vehicles from driving on the path.
This bollard has a design which allows the upper vertical portion to be separated from the base to allow access by maintenance and emergency vehicles.
This detachable base is not considered an acceptable breakaway device and cannot be placed in the Design Clear Zone of an adjacent highway.
