Abstract:
The 2,717 state highway bridges incorporated into this study from the WSDOT bridge inventory database were assessed using the BSST analysis methodology detailed previously in this report. Results consist of three types of outcomes: Bridge Damage Levels and Types, Bridge Repair Types, and Bridge Reopening Times. All output is a part of this feature class. Bridge damage types are projected on the basis of both damage level (None, Moderate, Significant), whether a bridge is a special bridge type, and also the types of damage that the bridge will experience (including both direct seismic and secondary earthquake-induced impacts); The projected repair types and reopening times necessary to bring bridges back to a minimum level of functionality that enables their use for emergency response were computed using the methodology specified in the Bridge Reopening Times section. Refer to the BSST Technical Report. The BSST was developed to assess the potential impacts of a CSZ earthquake to highway bridges in Washington State at a system-level as part of the Washington State Transportation Systems RRAP project. The results provided identify the Damage Levels, Damage Types, Repair Types and Reopening Times associated with 2,717 bridges located in Western and Central Washington that were evaluated for this RRAP project. Understanding that this analysis likely constitutes a “worst-case scenario” with respect to bridge damage, the results nonetheless project that the majority of bridges in Washington State will experience moderate to significant damage resulting from a CSZ earthquake. While the majority of bridges that experience damage could be reopened within one year of the earthquake, a substantial number of those bridges (28.7 percent) are projected to take more than a year to reopen—in many cases 2 or more years. The results also project that while many bridges may be reopened after either minor repairs/inspections or the construction of a temporary bypass road, a substantial number of more significantly damaged bridges (797 structures) span bodies of water and will require complete replacement prior to reopening. This suggests that significant gains in roadway corridor reopening times could be gained by focusing on retrofits or upgrades to these more vulnerable bridges that span rivers and other bodies of water. This tool is primarily intended to inform regional highway prioritization for emergency response activities; however, the BSST provides a useful evaluation methodology that could be applied to other regional emergency preparedness and infrastructure assessment studies. This could include studies of bridge infrastructure to other potential seismic events within the region, or at varying jurisdictional levels (i.e., county, local). The BSST also uses currently available seismic, seismically-induced secondary hazard and infrastructure information. As new seismic information becomes available, or as secondary-hazards (e.g., landslides, avalanches) become characterized more comprehensively, such information could be integrated into the current BSST methodology. Similarly, as seismic retrofit activities or other infrastructure improvement projects continue throughout Washington State, or as new infrastructure are built, it will be important that the infrastructure data integrated in the BSST also be updated periodically. Doing so will ensure that planners and infrastructure managers maintain the most current and complete understanding of the network-level seismic risks of a CSZ event to Washington State highways.Please note that all results from the BSST are based on a model and information received from WSDOT. Damages from an earthquake may be different that what is provided here. Liquefaction data was used within the BSST tool. WADNR is the source for liquefaction data and is available here: https://www.dnr.wa.gov/programs-and-services/geology/geologic-hazards/geologic-hazard-maps#nehrp-site-class-and-liquefaction-susceptibilityUSGS ShakeMap was also used in the BSST tool for a M9.0 Cascadia earthquake and is available here: https://earthquake.usgs.gov/scenarios/eventpage/gllegacycasc9p0expanded_se/shakemap/pga. DHS distributed this data to WSDOT on August 22, 2019.
Purpose:
The Regional Resiliency Assessment Program (RRAP) is a cooperative assessment of specific critical infrastructure within a designated geographic area and a regional analysis of the surrounding infrastructure that addresses a range of infrastructure resilience issues that could have regionally and nationally significant consequences. In 2017, the U.S. Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) sponsored the Washington State Transportation Systems RRAP project in coordination with the Washington Emergency Management Division (EMD), Washington State Department of Transportation (WSDOT), and other regional stakeholders. This project is focused on assessing the impacts of a Cascadia Subduction Zone (CSZ) earthquake on state transportation systems and, in particular, how those impacts may affect the ability of emergency response efforts to move supplies into the region. The intended outcome of this analysis is the prioritization of transportation routes and modes for additional planning, investment, hardening, or other activities to enhance their resilience—and therefore, to enhance their ability to support response and recovery efforts following a CSZ earthquake. An important part of this transportation system-level assessment has been to assess the seismic vulnerability of the state highway system. In doing so, the RRAP project team developed a Bridge Seismic Screening Tool (BSST) to assess, at a system-level, the potential impacts that a CSZ earthquake could have on state highway bridges. The first step in the BSST is to assess the seismic vulnerability of highway bridge infrastructure in Washington State following a CSZ earthquake to determine a projected or potential damage state. Damage states are then used to determine approximate reopening times for bridge crossings.

Attribute_Definition:
All bridge vulnerability and potential-damage analysis is ultimately used to inform the determination of an approximate bridge reopening time for each structure following a full-length rupture of the CSZ fault. Bridge reopening time is different from bridge repair time or restoration time; reopening time refers to the amount of time required to repair a bridge crossing to a minimum functional state of repair sufficient to support the movement of emergency response vehicles. It does not necessarily refer to complete restoration to a pre-event state of repair. The estimated reopening times include the time necessary to perform a bridge damage inspection, bridge rehabilitation or bridge replacement, or to construct a temporary road to bypass the bridge. Bridge reopening times were determined in collaboration with the WSDOT bridge engineers on the basis of damage criteria, bridge length, and repair type, See the Technical Report for Repair Times.

Attribute_Label: Latitude
Attribute_Definition:
Latitude is a north-south measurement of position on the Earth. It is defined by the angle measured from a horizontal plane located at the Earth's center that is perpendicular to the polar axis. A line connecting all places of the same latitude is termed a parallel. Latitude is commonly, but not exclusively, measured in degrees, minutes, and seconds. Measurements of latitude range from 0° (at the Equator) to 90° North (90.0) or South (-90.0).

Attribute_Label: Longitude
Attribute_Definition:
Longitude is a west-east measurement of position on the Earth. It is the angle measured from a vertical plane running through the polar axis and the prime meridian at Greenwich, UK. A line connecting all places of the same longitude is termed a meridian. Longitude is commonly, but not exclusively, measured in degrees, minutes, and seconds. Measurements of longitude range from 0° (Prime Meridian) to 180° West (-180.0) or 180° East (180.0) from this point.

Attribute:
Attribute_Label: InitialDamage
Attribute_Definition:
Initial Damage was calculated from the BSST Tool and is shown as no damage, moderate damage, and significant damage. Definitions are below. No Bridge Damage - Bridges identified as suffering neither significant nor moderate damage are assumed to sustain no structural damage during the CSZ earthquake scenario and thus assumed to not require any repairs prior to reopening. These bridges may suffer minor surface cracking. Moderate Bridge Damage - Bridges identified as suffering moderate damage of at least one damage type and not identified as suffering significant damage of any of the potential damage types are assumed to be moderately damaged following the CSZ earthquake scenario and related geological hazards. For such bridges, it is assumed that a bridge damage inspection would be necessary prior to reopening, but that limited or no bridge repairs would be required. Furthermore, it is assumed that the bridge inspection and any necessary repairs would require 2 weeks to complete, after which time the bridge would be reopened. Significant Bridge Damage - Bridges identified as suffering significant damage are evaluated within the BSST to determine the amount of time required to either repair or replace the bridge, or to build a temporary road that bypasses the bridge, if possible. Bridges suffering significant damage are considered damaged to such an extent that major bridge rehabilitation, partial rebuild, or complete rebuild would be necessary. Given the extensive time required for such work, the construction of temporary roadways to replace bridges when possible was deemed preferential in the BSST methodology. If it was determined that a temporary roadway could not be constructed, the bridge rehabilitation or replacement time was determined as a function of bridge length and considerations of any subsurface strengthening necessary to improve liquefied soils at the bridge location. Special Bridges - Used to specify bridges whose vulnerability and expected damage are atypical, and thus not amenable to standardized analysis. As such, bridges identified in this sheet are a subset of those listed in the master “RoadBridges” worksheet, and are excluded from the BSST analysis.

For a structure to be defined as rebuilt, the type of work performed, whether or not it meets current minimum standards, must have been eligible for funding under any of the federal aid funding categories. The eligibility criteria would apply to the work performed regardless of whether all state or local funds or federal aid funds were used. Some types of work to be considered as rebuilt are widenings and retrofits designed to increase the original structural capacity. Some types of eligible work not to be considered as rebuilt are: • Safety feature replacement or upgrading (for example, bridge rail, approach guardrail or impact attenuators). • Painting of structural steel. • Overlay of bridge deck. • Utility work. • Emergency repair to restore structural integrity to the previous status following an accident. • Retrofitting to correct a deficiency which does not substantially alter physical geometry or increase the load-carrying capacity. • Work performed to keep a structure operational while plans for complete rehabilitation or replacement are under preparation (for example, adding a substructure element or extra girder).
