Federal Aid Highway.
National Highway System.
State Highway.
National Highway Performance Program (NHPP).
Surface Transportation Program (STP).
Bridge Formula Program (BFP).
Federal Aid Highway.
Highways on the Federal Aid Highway System (the National
Highway System and the Dwight D. Eisenhower National System of Interstate and
Defense Highways) and all other public roads not classified as local roads or rural minor
collectors.
National Highway System.
Consists of roadways important to the nation’s economy,
defense and mobility. The National Highway System (NHS) includes the following
subsystem of roadways — interstate, other principal arterials, strategic highway network,
major strategic highway network connectors and intermodal connectors.
State Highway.
A public road owned by a state agency.
National Highway Performance Program (NHPP).
A federal aid transportation program to
provide support for the condition and performance of the NHS, and bridges on the federal
aid system, provide support for the construction of new facilities on the NHS and ensure
that the investments of federal aid funds in highway construction are directed to support
progress toward the achievement of performance targets established in a state’s asset
management plan for the NHS.
Surface Transportation Program (STP).
A federal aid transportation program to provide
flexible funding that can be used by the states and localities for projects to preserve and
improve the condition and performance on any federal aid highway, bridge or tunnel
project on any public road, pedestrian or bicycle infrastructure or transit capital projects,
including intercity bus terminals.
Bridge Formula Program (BFP).
Federal aid highway formula funding established in the
Infrastructure Investment and Jobs Act, Public. Law 117-58 (Nov. 15, 2021) to fund
highway bridge replacement, rehabilitation, preservation, protection, and construction
projects on public roads.
State Funding
The state collects revenue for highway and bridge work from several sources, including:
* State user fees
* State sales and use tax earmarks
* General fund appropriations
* Local option sales and use taxes and fees
* Gas taxes
* To match federal aid funds
* For 100% state funded capital projects and maintenance
AASHTOWare Bridge Management
bridge management software that records bridge inventory
and inspection data, develops optimal preservation recommendations, simulates conditions,
generates work candidates and, ultimately, develops a bridge program.
Bridge Preservation.
Actions or strategies that prevent, delay or reduce deterioration of
bridges or bridge elements, restore the function of existing bridges, keep bridges in good
condition and extend bridge life.
(BMS)
The Bridge Management System
* Improving decision making, supported by policies, performance based goals, performance
measures and appropriate maintenance levels
* Basing decisions on accurate data, engineering and economic analyses
* Providing a long term view of assets
Bridge Rehabilitation.
Work required to restore the structural integrity or correct safety
deficiencies. Actions including bridge widening and deck replacements.
Bridge Replacement.
Total replacement of a bridge with a new facility constructed in the
same general traffic corridor.
Bridge Maintenance.
Minor bridge treatments to address immediate needs and to extend
bridge life.
Bridge Health Index (BHI)
BHI = (Deck Score × 0.40) + (Superstructure Score × 0.35) + (Substructure Score × 0.25)
Bridge Emergency.
Bridge work requiring immediate attention to address a critical defect.
Criticality Score.
Reflects the overall numerical value of the criticality of the bridge based on a summation of the individual scores of each importance factor.
Vulnerability Score.
Measures the overall risk of a structure based on the physical
condition of the structure.
Vulnerability Scoring
A vulnerability score is assigned to each bridge using a summation of the following:
* BPI Score: 75 pts max
* Load Rating Score: 25 pts max
Total: 100 pts max
Vulnerability Score = 0.75(BPI) + LRS
Significance Factor
The significance factor is a score
determined by the length to bypass an
out of service bridge.
Time to Restore
– Delay Factor
The time to restore is a measure of the cost of
downtime from not having a bridge in service.
