New load postings issued by state for Clark Fork River Bridge - Clark Fork Valley Press

The Montana Department of Transportation recently issued new load postings for the Clark Fork River Bridge in St. Regis, on Old Highway 10 E, in Mineral County.

A posted bridge is safe to use, but the weight of certain vehicles must be limited accordingly.

The new posting on the Clark Fork River Bridge applies to specialized hauling vehicles; it limits the maximum gross vehicle weight of single-unit emergency vehicles to the following: Single axle – 17 tons, Tandem – 19 tons, Gross – 40 tons.

The postings are part of a multi-year effort to update load ratings and postings on Montana bridges as mandated by the Federal Highway Administration.

The federal mandate is in response to changes in the trucking industry over the last decade. Truck manufacturers are building specialized hauling vehicles, which are capable of legally carrying heavier loads than typical vehicles have in the past.

The specialized vehicles are single-unit, short-wheelbase, multiple-axle trucks commonly used in the construction, waste management, bulk cargo and commodities hauling industries.

Often one or more axles can be raised or lowered as needed to comply with statutory weight limitations.

These special vehicle configurations concentrate heavy loads over a short length, and they have been found to cause too much stress to bridges beyond what was previously modeled by standard commercial vehicles.

To account for their increasing presence and ensure safe operation, federal officials have determined that all states must include these new, short, heavy vehicles when evaluating the safe limits of bridge capacity.

To comply with the mandate, the state is currently updating load ratings for 4,500 public bridges across the state, including approximately 2,500 owned and maintained by the Montana Department of Transportation.

This effort is expected to take about four years to complete.

Bridge weight restrictions are required when the engineering analysis of a bridge, known as a load rating, indicates that it cannot carry standard, legal loads.

Load ratings provide information about how much distributed weight can safely pass over a bridge. Load posting signs show maximum weight limits for different vehicle types, depending on their axle configuration.

Further information on understanding and interpreting Montana’s weight limit signs and silhouettes can be found in MDT’s load posting brochure, located here: http://bit.ly/mtbridgebrochure.

To assist with public outreach and education about the bridge load posting program, MDT has created an interactive map with statewide load posted bridge locations available here: http://bit.ly/mtbridgemap.
