Tetra Tech INCA inspected and rated 42 bridges throughout Washington State, of which 16 were pedestrian and 26 vehicular. Each bridge was thoroughly inspected and the results compared with previous inspection reports.

INCA performed load ratings based on current WSDOT bridge load rating procedures utilizing WSDOT’s BRIDG software. INCA subsequently prepared a report outlining the condition and physical aspects of each bridge. Structures inspected included prestressed concrete, spandrel arch concrete, steel truss, glulam beam, and suspension bridges.
