REPLACEMENT AND REHABILITATION PLAN FOR DEFICIENT BRIDGES <br />Kittitas 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 />- 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, minor deck patching, and bridge rail replacement. Contractors provide <br />support with resources not available to County road crews. <br />In 2023 Public works road crews performed multiple maintenance work orders that included asphalt <br />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 />OB. Public Works road crew worked to place material and armor the structure to prevent future scour. <br />Due to concerns about the structure, beginning in 2018 Public Works began monitoring bridge no. 87244- <br />OB. This monitoring included collecting survey data on set points then comparing those to the baseline <br />year. This monitoring effort continued through 2021, with no significant movement observed. In 2022 <br />Public Works worked with a contractor to place control density fill at either abutment. The placement of <br />the fill will slow the erosion and degradation of the material and extend the life of the bridge. Additional <br />monitoring 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. <br />CONSULTANTS <br />Kittitas County 2024 Annual Bridge Report <br />
