BACKGROUND The Federal Highway Administration (FHWA) and Washington State Department of Transportation (WSDOT) require regularly scheduled inspections of all the City's vehicle -carrying bridge structures. The City extends this effort to include its pedestrian bridges. This requirement allows for continuity in reporting, as well as the opportunity to identify and potentially fund bridges in need of replacement and rehabilitation. ANALYSIS The City currently owns 24 bridges (16 traffic bearing and 8 pedestrian). Of those, two are jointly -owned jurisdictional bridges with shared ownership between the City of Renton (Grady Way) and the City of Kent (S 196th1200). The following discussion will focus on why the City inspects its bridges, where the City stands in comparison to the state and the country, and recommendations for additional steps that can be taken to address known issues. There were no new key findings or major concerns observed during the 2022 inspections. With available funds in 2022, TranTech Engineering performed a study to evaluate which structures require bridge seal replacement. City staff plans to use the remainder of the 2023 bridge maintenance funds to replace deteriorated bridge seals. The following structures were inspected in 2022: Bridge Number Bridge Name Date Inspected Tukwila 05 Southcenter Blvd 8/16/2022 Tukwila 14 42nd Ave S 3/8/2022 Tukwila 15 Tukwila International Blvd 8/16/2022 Tukwila 18 Green River Trail Pedestrian 8/16/2022 Tukwila 19 Interurban Trail Bridge 8/18/2022 Tukwila 20 180th Pedestrian Bridge 8/16/2022 Tukwila 21 Fort Dent Park Bridge 8/18/2022 Tukwila 22 Fort Dent Trail Bridge 8/18/2022 Tukwila 25 Tukwila Urban Center Ped Bridge 8/18/2022 Tukwila 26 Riverton Creek Pedestrian 8/16/2022 43 2023 Scheduled Inspections A total of 14 of the 24 bridges are planned to be inspected in 2023. One of the bridges being inspected in 2023 is the S 119' St pedestrian bridge, which is scheduled to receive an inspection in April. The structure receives an inspection every 24 months due to some of the deterioration observed in the 2017 special climbing inspection. The structure was constructed in 1960 and is nearing the end of its useful life. The bridge timber deck and timber beams have multiple areas of timber rot and paint loss. The structure is scheduled to receive paint and epoxy to the timber deck and timber beams in 2024. The scheduled repair work is considered preventive maintenance and does not improve the structural integrity of the bridge. A rough order magnitude (ROM) to replace the structure is approximately $3.9 million. City staff are actively searching for grant funding opportunities for repairs or replacement of the S 119th street bridge. FISCAL IMPACT The cost for King County to perform the 2022 inspections was $19,500.00, which was under the 2022 project budget of $45,000.00. RECOMMENDATION Discussion only.

Of those, two are jointly owned jurisdictional bridges with shared ownership between the City of Renton (Grady Way) and the City of Kent (S 196th/200). The different types of bridge configuration vary from steel through truss, pre -cast concrete girders, cast -in-place concrete girders, steel girder, wood girder, and steel tied arch spans. Currently the City has a total of six (6) bridges that have a sufficiency rating between 80 to 100; seven (7) bridges that have a sufficiency rating between 60 to 79; two (2) bridges that have a sufficiency rating between 40 to 59; and one (1) bridge (42nd Ave S Bridge) that have a sufficiency rating of 39 or less. Note, pedestrian bridges do not receive a sufficiency rating. Please refer to the Quick Bridge Reference sheet for the break down of city owned bridges and the assigned sufficiency rating. The sufficiency rating formula provides a method of evaluating highway bridge data by calculating four (4) separate factors to obtain a numeric value which is indictive of bridge sufficiency to remain in service. The result of this method is a percentage in which 100 percent would represent an entirely sufficient bridge and zero (0) percent would represent an entirely insufficient or deficient bridge. The formula considers the structural adequacy, functional obsolescence, level of service and essentiality for public use. i i 50 Forward The City Engineer's Bridge Inspection Report, dated March 2023, is published by the City of Tukwila Public Works Department, and the information contained herein is the best available at the time of publication. It is to be used as an information tool for planning and maintenance activities, and reflects the general condition of the City's bridges. The repairs indicated are summarized for brevity from actual bridge inspection reports. Background The FHWA (Federal Highway Administration) issued the NBIS (National Bridge Inspection Standards) in 1971. These standards established a comprehensive inspection for all federal highway system bridges. Minimum qualifications were set forth for bridge inspectors. Specific types and frequencies of inspections for bridges were established, and the reporting of certain standard information about each bridge was required. In 1978, these requirements were extended to all public bridges carrying vehicular traffic. A national bridge inspection program has been in place ever since, and state and local agencies have performed bridge inspection in accordance with these guidelines. Inspections for the City of Tukwila's bridges are conducted every two years unless conditions warrant additional inspections or frequencies as dictated by the NBIS. iii 51 Bridge Quick Check Informational Sheet Bridge Number Name Year Built Suff.

Transportation Project Manager 6300 Southcenter Blvd., Suite 100 Tukwila, WA 98188-2544 RE: Inspection of City of Tukwila Bridges Dear Mr. Cox: King County bridge engineers inspect the bridges owned by the City of Tukwila, in accordance with agreements between the City of Tukwila and King County Department of Local Services. The bridge inspections were conducted as follows: Interim Inspection February 26, 2022 No. TUKxNx14, 42nd Ave South Bridge Routine Inspections August 16, 2022 August 18, 2022 No. TUKxNx05, SC Blvd. Green River Bridge No. TUKxNx15, Tukwila International Boulevard No. TUKxNx18, Green River Ped & Utility Bridge No. TUKxPx20, 180th Pedestrian Bridge No. TUKxPx26, Riverton Creek Ped Bridge No. TUKxPx19, Interurban Trail Bridge No. TUKxNx21, Fort Dent Park Bridge No. TUKxPx22, Fort Dent Trail Bridge No. TUKxPx25, Tukwila Urban Center Ped Bridge Enclosed are the reports from the bridge inspections and the actions we recommend you take to maintain the bridges. We submit the data in the report to Washington State Department of Transportation (WSDOT), in accordance with state and federal laws, to inform them of the bridge's condition and to assure them the bridge has been inspected on a timely basis. The information is incorporated into state and federal databases. 60 DocuSign Envelope ID: B035BA52-CBD6-4F80-9095-92131F2FDD34 Adam Cox, P.E. December 7, 2022 Page 2 The bridge inspection report is divided into three main sections. The first section consists of three parts: the National Bridge Inspection Standards (NBIS) elements, Load Capacity Information, and Inspections Performed. The NBIS fields, which are numbered 1657 to 1687 are used for rating the components of the bridge. In general, the codes rate the components from eight (best) to one (worst); however, other rating scales apply to some of the fields in this first section. Explanations of these codes are found in the Washington State Bridge Inspection Manual (https://www.wsdot.wa.gov/publications/manuals/fulltext/m36-64/Bridgelnspection.pdf). The second section of the report, Bridge Management System (BMS) Elements, lists quantities and rates them, breaking down the condition of each component into categories that indicate how widespread a component is deteriorated. State 1 is best; State 4 is worst. The third section consists of three parts: Notes, Repairs, and Inspection Resources Required. The Notes section is comprised of information that provides details of the numbered fields in the first two sections. Please note that any deficiencies listed in the "Repairs" section are prioritized between 1 - High priority, and 3 - Low priority. The Resources Required section indicates any special equipment or tools used to inspect the bridge. I hope this letter helps you in reviewing these inspection reports. We recommend that the City of Tukwila bridges continue to be inspected on a 24 -month schedule. Our next scheduled inspections of the City of Tukwila Bridges will be in spring 2023. Please call Margaret Germeaux at 206-477-3539 if you need any additional information. We appreciate assisting your city with bridge engineering and inspection services.
