Purpose: Replace eligible bridges that are unsafe due to structural deficiencies, physical deterioration and/or functional obsolescence.

Overview: The B.R.O.S. program is a federally funded bridge replacement program to reduce the number of deficient off-system bridges. It applies to bridges owned by cities, towns and counties, located on a non-federal aid roadway and open to the public.
An eligible deficient bridge is a structure with a sufficiency rating of 80 or less, classified as structurally deficient or functionally obsolete, and appears on the Federal Highway Administration’s Selection List. Eligible bridges having a sufficiency rating less than 50 qualify for replacement funding. Eligible bridges having a sufficiency rating of 80 or less may be considered for rehabilitation if the public jurisdiction has no bridges qualifying for replacement funding. A rehabilitated bridge must have an extended service life and meet minimum design criteria.

B.R.O.S. Program Features and Facts

  • A bridge is defined as a structure having an opening of more than 20 feet. This may include multiple pipes when the clear distance between the openings is less than one-half of the smaller contiguous opening.
  • WYDOT conducts an inspection of all bridges within the state at least once every 2 years. The inspection results are reported to the Federal Highway Administration (FHWA), which determines the sufficiency ratings for each structure. Bridges having a sufficiency rating of 80 or less and classified structurally deficient or functionally obsolete are placed on the FHWA Selection List and considered deficient.
  • The sufficiency rating is used as the basis for establishing eligibility and priority for replacement, and not as a direct measure of the structural adequacy or safeness of a bridge.
  • WYDOT’s Bridge Program maintains a Bridge Condition Index which is based on bridge inspections. The Bridge Condition Index can be used to prioritize off-system bridge replacement projects
  • To be considered for replacement in WYDOT’s B.R.O.S. program, the sponsoring entity or jurisdiction must submit to WYDOT’s state bridge engineer a request identifying the structure number, route and milepost.
  • WYDOT’s Bridge Program will review and verify the structure is eligible, and will notify the local agency confirming its eligibility. Consideration is given to a fair and equitable distribution of replacement projects throughout the state.
  • The matching fund ratio for B.R.O.S. projects is currently 90.49 percent federal-aid funds and 9.51 percent local funds.
  • WYDOT is responsible for administration and management of all B.R.O.S. projects. WYDOT or its contract consultant will complete the preliminary engineering, design, specifications and contract bid documents, bid advertising and bid award, construction contracting, construction engineering, inspection, environmental clearances and documents, and project completion/acceptance.
  • With B.R.O.S.-funded projects, WYDOT is responsible for right-of-way and utility clearance. Acquisition of right-of-way or payment for utility adjustments is an eligible expense to include right-of-way purchases by WYDOT on behalf of the local entity. The local entity shall ensure the structure is within a dedicated public right-of-way prior to the project request.
  • Deviation requests are reviewed by WYDOT Bridge and Project Development programs, and their acceptance approved by WYDOT’s Executive Staff.
  • B.R.O.S. projects may include a nominal amount of approach roadway work necessary to incorporate the replacement bridge into the existing roadway or to return the grade line to an attainable touchdown point, using sound geometric design practices.
  • Prior to bidding a B.R.O.S. project, final design plans and cost estimates must be approved by the local sponsoring agency prior to advertising for bid.
  • Maintenance of a completed B.R.O.S. project is the responsibility of the local jurisdiction.
  • Should the local entity desire a breakdown of expenditures on a B.R.O.S. project, a list of project costs can be requested from WYDOT’s local government coordinator. Additionally, the local sponsoring entity may request WYDOT’s Internal Review Program to conduct an audit of project costs, if the local entity questions the charges or expenditures on a project.
  • Debris from demolished bridges will be made available to federal, state or local governments for erosion control, bank stabilization, ecosystem restoration or marine habitat creation. The recipient shall bear the costs of processing, delivery, placement, use and shall assume all legal responsibilities for placing the material.
