Bridge Management is responsible for bridge asset management, planning and programming, operations (inspections and load ratings), maintenance and emergency response functions.
Bridge asset management strives to maintain a safe transportation system by managing the bridge infrastructure. The health of the bridge system is measured using condition ratings. The bridge inventory continues to be safe with an overall rating of “good” and bridges rated “poor” are proactively addressed.
Bridge Planning and Programming advances efforts in asset management and develops a program considering bridge condition and performance measures associated with changes in funding. The goal is to implement risk-based decision making and cross asset optimization.
Bridge Operations administers the Bridge Inspection Program and Bridge Load Rating Program. FHWA requires each bridge to be inspected every two years. The Bridge Inspection Program measures and reports the overall health of the bridge inventory to support asset management activities. Performing bridge load ratings ensures a safe transportation system for the traveling public and facilitates the effort to effectively evaluate the trucking industry requests for allowance of higher truck loads. Bridge Operations oversees all maintenance and emergency response activities related to bridges including coordinating bridge maintenance with the stations, providing technical expertise and response to bridge collisions and other related emergencies.
Federal legislation requires that the highway system be maintained in a state of good repair. Bridge asset management tracks the condition of bridges by the major highway systems; the National Highway System (NHS), the remaining state highway system (State, Non-NHS), the locally owned on the Federal Aid Highway System (Local-FA) and the locally owned off the Federal Highway System (Local, Non-FA). The overall condition of each system can be seen in the figure, right.
· Maintained bridge condition to an overall good rating. The Department currently has 1,903 state bridges, including pedestrian and UTA bridges, with 40 rated in poor condition based on Bridge Health Index.
· Completed the Load Rating Program
· Published the 2016 Annual Bridge Report
· Implemented a Bridge Maintenance Program, providing rapid response to bridge deck repairs
· Completed over 1500 bridge inspections, completing the first year cycle utilizing AASHTO Elements
· Reduced the number of scour critical bridges on the state system
2017 Performance Goal
· Advance a barrier program to replace or retrofit vulnerable bridge railings
· Meet the Department committed goal to having no more than 10% of the state bridge system carrying traffic rated in poor condition and having action plans in place to repair or replace each bridge when needed
· Meet the federal legislative requirements of:
- Maintain the bridge network in a state of good repair
- Maintain a National Highway System with less than 10% of the bridge deck area rated in poor condition
· Develop Load Posting Mitigation Program
· Continue to reduce the number of scour critical bridges on the state system
· Build on 3D technology to maximize bridge management objectives
