Kittitas County Public Works utilizes consultants to complement work done by the County and fill in where <br /> technical expertise is needed. This includes the use of consultants for on-call structural analysis and for <br /> bridge inspection.Through the procurement process, Public Works solicits qualified consultants to be on <br /> the on-call list.On-call work is typically under a two-year agreement. <br /> FLOOD WATCH AND EMERGENCY ROUTE <br /> In 2021 Public Works installed real time flow monitoring on the Charlton Road Bridge over Naneum Creek <br /> (Bridge No. 98288). Monitoring is being done to aid in flood watch.This may help to identify patterns of <br /> flooding downstream and impacts to other bridges. <br /> Five remote sensing locations are monitored throughout the County.This includes three bridge locations <br /> (Manastash Road over Manastash Creek;Teanaway Road over North Fork Teanaway River;Charlton Road <br /> over Naneum Creek),one culvert location (Wilson Creek Road over Wilson Creek)and one at an irrigation <br /> weir(Naneum Creek north of Bar 14 Road). <br /> LOAD RESTRICTED BRIDGES <br /> Each bridge is required by National Bridge Inspection Standards (NBIS)to have a Load Rating calculation. <br /> The Load Rating establishes how much weight the bridge can carry compared to a series of truck <br /> configurations. A bridge which is unable to safely carry the full load of any of the truck configurations is <br /> classified as a"Load Restricted Bridge"and is posted weight limited. Currently there are 18 bridges within <br /> Kittitas County jurisdiction which are classified as"Load Restricted".Appendix C includes a map and listing <br /> of load restricted bridges. <br /> Prior to 2017,there were three standard truck configurations which were used to calculate load rating on <br /> bridges. In 2017 eight new configurations were added for review. The additional truck configurations are <br /> a result of new trucks that have been introduced by the trucking industry over the past decade. The <br /> configurations vary by number and spacing of axles as well as overall vehicle weight. Kittitas County Public <br /> Works has completed a project to provide updated load rating calculations to include the new <br /> configurations for each bridge. <br /> Kittitas County 2024 Annual Bridge Report <br />
