Policy
MASH requires all barriers, including temporary barriers, to meet its crash test criteria.
Bridge railings that will be permanent in the final bridge, but act as temporary barriers during construction, must be installed with all their components for the full duration of use, and must satisfy the minimum height specified for the rail.
Selection of Temporary Barrier or Railing
Selection of Temporary Barrier or Railing
Some factors that weigh into the selection of an appropriate temporary barrier or bridge railing are:
- Traffic volume and mix (for example, percentage of truck traffic)
- Posted speed within the work zone
- Width of temporary lanes, number of lanes, and shoulder width, if applicable
- Alignment of the bridge (that is, curves and grades)
- Duration of construction.
