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 23 bridges (16 traffic bearing and 7 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 196th/200). The bridge structure types vary from steel through truss, pre -cast concrete girders, cast -in-place concrete girders, steel girder, wood girder, and steel tied arch spans. The discussion will focus on why the City inspects its bridges, where the City stands with respect 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 2021 inspections. The following structures were inspected in 2021: Bridge Number Bridge Name Date Inspected Tukwila 01 Macadam Road Bridge 4/27/2021 Tukwila 02 42nd Ave S Frank Zepp 4/7/2021 Tukwila 03 Lois T Newton Bridge 5/19/2021 Tukwila 06 Foster 56 Ave S Bridge 4/22/2021 Tukwila 07 51st Ave S Bridge 4/22/2021 Tukwila 08 Grady Way Bridge 4/13/2021 Tukwila 09 East Marginal Way Bridge 4/13/2021 Tukwila 11 Boeing Access Road over Airport Way 8/02/2021 Tukwila 12 Boeing Access Road over BNRR Bridge 4/14/2021 Tukwila 13 Beacon Ave S Bridge 4/8/2021 Tukwila 14 42nd Ave S Bridge 4/20/2021 Tukwila 16 S 119th Street Bridge 4/27/2021 Tukwila 24 Klickitat Bridge 4/22/2021 4001 196th/200th Street Bridge 4/7/2021 https://tukwilawa.sharepoint.com/sites/publicworks/engineeringlPW Drop Box/01 TIC Agenda/2021 Agenda Items/TIC 11-08-21/3. 2021 State of Bridges/Info Memo_State of Tukwila's Bridge's_2021 11 08.docx 29 Three bridge's sufficiency rating (SR) increased after the 2021 inspection cycle.

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. ii 34 Forward The City Engineer's Bridge Inspection Report, dated November 2021, 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 35 Bridge Quick Check Informational Sheet Bridge Number Name Year Built Suff.

The structure is still safe for use by the public and the condition is being monitored. FO - Indicates the bridge structure is "Functionally Obsolete" as defined by the WSDOT (Washington State Department of Transportation) bridge inspection program. This designation only indicates the roadway geometrics do not meet current standards for bridge design. UBIT - Under Bridge Inspection Truck. This indicates the bridge needs special equipment in order to reach portions of the structure for inspection. ADT - Average Daily Traffic NA - Sufficiency ratings are not given on pedestrian facilities since they are not a part of the NBI system, a Suff. Rating of NA is given in that location. All pedestrian bridges do not have a calculated sufficiency rating - they are not traffic loaded bridges and the rating numbers are not calculated per Federal Requirements. *Traffic counts were not recorded in 2020 due to inconsistencies in traffic volumes. iv 36 Bridges Recommended for Replacement or Rehabilitation Bridge Number Bridge Name Location Reason Tukwila 14 42nd Ave South* Allentown (42nd Ave) Deteriorating Structural Condition of the steel superstructure Note: See individual bridge reports in Public Works for detailed repair work. * The City has been awarded two federal grants from PSRC and the Local Bridge Program for a total of $13.5M 1 37 Bridges Recommended for Major Maintenance Bridge Number Bridge Name Location Reason Tukwila 16 South 119th Pedestrian Bridge 119th Str (Allentown) Painting/Epoxy of entire structure with possible rot repair as encountered Tukwila 18 Green River Pedestrian and Utility Interurban Trail near 180th Rehabilitation of structure coating and timber rot repair and replacement 2 38 Posted Bridges Bridge Number Bridge Name Location Reason Tukwila 14 42nd Ave South Allentown Bridge is posted for reduced truck speed and posted for reduced loading on AASHTO Type 3 trucks and 6 and 7 axle vehicles.

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. 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 (http://www.wsdot.wa.gov/TA/Operations/BRIDGE/BIC.html). 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 2022.
