Bridge Structure Management (BrM) System

The Bridge Management Section is responsible for the inspection, operation and reactive maintenance of the state system bridges and provide guidance for local agencies. This includes:

In-Service Bridge Inspection. The Section has responsibility for overseeing a program of regular condition inspections of all in-service publicly owned bridges in accordance with the National Bridge Inspection Standards (NBIS) and operation of the Structure Management System (BrM) database that is used to track and report system-wide conditions and perform analysis that supports bridge funding decisions.
Load Rating. Engineers perform analysis and load rating to determine safe operation and for all publicly owned in-services bridges. Load Rating Engineers will recommend load posting, restriction or closures for deficient bridges.
Overweight Vehicle Permitting. Permitting Engineers determine safe operating conditions for overweight trucks using the states' transportation system. Overweight truck configurations are analyzed to determine if they can safely cross a bridge without causing damage. Engineers provide recommendations to MDT Motor Carrier Services on overweight truck routes and permits.
Bridge Maintenance. Bridge Maintenance Engineers perform or develop contracts for structural repairs to bridges on the state system. They offer guidance to MDT District Maintenance and Local Agencies for routine maintenance and technical assistance.

Montana’s Bridge Structure Management System (BrM) is used to track and report system-wide conditions and perform analysis that supports bridge funding decisions.
