Significance: The Smith River Bridge was a rare California example of the cantilever highway truss bridge, a bridge type that enjoyed brief popularity during the decade spanning the late 1920s to the late 1930s. Because the type was best suited to specialized applications, only limited numbers were built in the State. Indeed, there are only seven remaining, following removal of the Smith River Bridge. The Smith River Bridge was the first cantilever bridge design executed by State Highway engineers, and likely was influenced by D.B. Steinman's Carquinez Bridge (1923-27).

1. CONTEXTUAL VIEW OF BRIDGE IN SETTING, LOOKING SOUTHWEST, FROM DOWNSTREAM. Crew, vehicles, boats, and equipment are from the California Department of Transportation's Transportation Laboratory conducting test borings for the replacement bridge.
2. CONTEXTUAL VIEW OF BRIDGE IN SETTING, LOOKING NORTHEAST, FROM UPSTREAM
3. VIEW OF DOWNSTREAM ELEVATION, LOOKING SOUTHWEST
4. OBLIQUE VIEW OF UPSTREAM ELEVATION, LOOKING NORTH
5. APPROACH VIEW FROM CRESCENT CITY (SOUTH) END OF BRIDGE, LOOKING SOUTHEAST. Emergency bracing under collapsed cantilever tower visible inside trusses.
6. APPROACH VIEW FROM OREGON (NORTH) END OF BRIDGE, LOOKING NORTHWEST
7. OBLIQUE VIEW OF NORTH PORTAL AND DOWNSTREAM SIDE OF BRIDGE, LOOKING WEST. Lights and illuminated sign on portal bracing were elements of an overheight load warning system designed to eliminate accidents of the type which damaged the bridge. However, the system was in place only on the north side of the bridge, controlling trucks approaching from Oregon. In theory, trucks with overheight, overwidth, or overweight loads from California would be controlled by the State's permit system. In fact, it was a 'permit' load originating in California, being hauled without the requisite permit which struck and damaged the bridge.
8. OBLIQUE VIEW OF DOWNSTREAM SIDE OF BRIDGE, LOOKING WEST
9. VIEW, LOOKING SOUTHEAST, ALONG CENTERLINE FROM SOUTH CANTILEVER TOWER. Note emergency bracing installed beneath collapsed tower, and crumpled vertical members at right and left.
10. VIEW, LOOKING NORTHWEST, ALONG CENTERLINE FROM SOUTH CANTILEVER TOWER, BACK TO SOUTH PORTAL. Note emergency bracing and crumpled vertical members.
11. VIEW, LOOKING SOUTHEAST, ALONG CENTERLINE FROM SOUTH CANTILEVER TOWARD TOWARD NORTH PORTAL. Note vertical displacement in deck caused by partial collapse at point of connection between south cantilever arm and suspended span.
