Bridge & structures inspection

After designing and building a structure, it's important to continue taking care of it through inspection and maintenance. These pages are tools and resources for those inspecting our structures.

Bridge Inspection Manual

The Washington State Bridge Inspection Manual (WSBIM) has been developed to provide specific guidance, offer needed technical details, and serve as an information source to both state and local agency staff related to and involved with bridge inspections within the state of Washington. The intent of this manual is to serve as an operations manual for the collection, processing and reporting of bridge inspection information.
