Bridges Master Plan

Print

The Federal Highway Administration (FHWA) bridge sufficiency formula is rated on a 0 - 100 scale, with 100 reflecting the highest rating. The rating is based on four variables:

1) structural adequacy and safety (55%)
2) serviceability (30%)
3) essentiality for public use (15%)
4) special reductions (up to 13%)

If a bridge is deemed Structurally-Deficient or Functionally-Obsolete, as determined by FHWA, and has a Sufficiency Rating of less than 50%, then the bridge qualifies for replacement per FHWA. As of April 15, 2014, 40% of the City's bridges had a Sufficiency Rating of less than 50% and are either Structurally Deficient or Functionally Obsolete.

The City has developed a scope of services to prepare a Bridge Maintenance Master Plan that will review, rate and prioritize the condition of the City's multiple bridges. The plan will provide a strategic approach to implementing a maintenance, repair and replacement schedule to insure the integrity of the bridge infrastructure. The plan will provide cost estimates to appropriately forecast investments needed over multiple years.
