Part 8830.1700 - GUARD RAIL

Subpart 1. Lateral escape route.

Where local road conditions permit, a lateral escape route to the right of the roadway in advance of the active warning device must be kept free of guard rails or other aboveground obstructions such as walls or fences.

Subp. 2. Responsibility for installation, maintenance, and costs.

Installation, maintenance, and costs of guard rails along the roadway are the responsibilities of the road authority. Where guard rails are considered necessary or appropriate by the road authority, rigid non-yielding-type barriers are not to be used for protecting active warning device supports.

In industrial and other areas where roadway traffic travels at 25 miles per hour (40 kilometers per hour) or less and where active warning devices are susceptible to being struck by turning truck traffic, such as in terminal areas, alleys, and warehouse areas, a ring-type guard rail may be installed to provide protection for the active warning device support. Installation, maintenance, and costs of ring-type guard rails are the responsibilities of the rail carrier.
