4 <br /> 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 />
