REPLACEMENT AND REHABILITATION PLAN FOR DEFICIENT BRIDGES <br />The County's focus is to replace or rehabilitate bridges that are classified as structurally deficient, <br />functionally obsolete or weight restricted. The current Six Year Transportation Improvement Plan includes <br />the following bridge projects: <br />Replacement <br />- Liberty Road —Swauk Creek Bridge (Bridge no. 07101) <br />- Cooke Canyon Bridge (Bridge no. 80181) <br />- Faust Road Bridge (Bridge no. 88212) <br />- Lambert Road Bridge (Bridge no. 06345) maintenance <br />- Reecer Creek Road over Towne Ditch (Bridge no. 88273) <br />Short Span bridges do not qualify for State or Federal funding assistance. These smaller structures serve <br />an important role in the County's transportation network. Short Span bridges are also reviewed and <br />recognized for their deficiency and need for repairs. The TIP also includes the following project: <br />- Short Span Bridge Replacement — Phase 1 <br />MAINTENANCE AND REPAIRS <br />Bridge maintenance and repairs are accomplished by a combination of County Forces and contractors. <br />This work includes cleaning and minor deck patching, and bridge rail replacement. Contractors provide <br />support with resources currently not available within the County. <br />In 2023 Public works road crews performed multiple minor maintenance work orders that included <br />asphalt patching bridge decks, replacing damaged and missing bridge rail components, and trimming and <br />removing brush and trees interfering with bridge elements and sight distance issues. <br />Examples of more significant maintenance repairs include maintenance work completed at two bridges in <br />2022 using contracted forces that performed the following: <br />Through the inspection process undermining was identified along the abutment for structure no. 89092- <br />CB. Public Works road crew worked to place material and armor the structure in order to help prevent <br />future scour. <br />Due to concerns about the structure, beginning in 2018 Public Works began monitoring bridge no. 87244- <br />OB. In addition to the regular inspections, monthly monitoring of the structure occurs. This monitoring <br />includes collecting survey data on set points and then comparing those to the baseline year. This <br />monitoring effort continued through 2021, with no significant movement observed. In 2022 Public Works <br />worked with a contractor to place control density fill at either abutment. The placement of the fill will <br />slow the erosion and degradation of the material and extend the life of the bridge. Additional monitoring <br />was done, and determined to discontinue after the repair. <br />Maintenance work orders are generated based on inspections performed. Work orders are prioritized by <br />Public Works staff. This information is then provided to Road Maintenance that then performs the repair. <br />Contracting construction services are also used to perform needed repairs.CONSULTANT <br />Kittitas County 2023 Annual Bridge Report <br />
