This map service provides general bridge information for all transportation structures within the Washington State Bridge Inventory System (WSBIS) in Washington State. This includes bridges, large culverts, tunnels, pedestrian & railroads passing over state routes, and pedestrian bridges adjacent to state routes on state right of way. The accuracy and completeness of the transportation structure data (including the structure location) are the responsibility of the structure owner. In cases where pedestrian & railroad structures pass over state or local agency routes, this data may be the responsibility of the route owner under the structure. Note that local agencies do not include a complete inventory of pedestrian & railroad structures in local agency rights of way. Please Note: If there is a vertical clearance restriction related to the bridge/structure, the minimum clearance will appear in either the MinVertClrncOverDeck, MinVertClrncUnderBridge or TunnelMinVertClrncOverRdBy10 fields.
