Priority 4: Bridge Rail Improvements – Code 2 <br />Phase 1- County Maintenance Districts A - D <br />• 6 bridges or structures <br />Phase 2- County Maintenance District E <br />• 16 bridges or structures <br />Phase 3- County Maintenance District F <br />• 17 bridges or structures <br />Phase 4- County Maintenance District G <br />• 21 bridges or structures <br />Phase 5- County Maintenance District H - I <br />• 14 bridges or structures <br />Phase 6- County Maintenance District J - K <br />• 14 bridges or structures <br />Phase 7- County Maintenance District L <br />• 12 bridges or structures <br /> <br />The second highest risk bridges or structures were rated as Code 2. These bridges have railing that do not meet <br />WSDOT’s modern standards for crashworthiness and do not have approach railing. Many of these bridges have w- <br />section metal beam rail and steel posts attached to the outer edge of the bridge deck. This is a design that was crash <br />tested and approved by FHWA in 1959 and has since been discontinued due to a tendency of the concrete deck to <br />fail at the post connection upon impact, allowing errant vehicles to continue off the deck. Bridges without approach <br />railing do not provide any protection to an errant vehicle that leaves the roadway just before the bridges. There are <br />100 bridges that are coded 2 throughout Kittitas County. As with priority 2, this project will be broken into 7 phases to <br />create more manageable projects for design and construction. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />
