The document discusses a presentation on strengthening the stringers of the historic Bridge of the Gods in Oregon. The bridge's load posting was restricted in 2013 due to insufficient stringer capacity. A strengthening project installed new connections between the deck and mid-span stringers to provide lateral bracing in accordance with codes. This increased the load posting from 8 to 40 tons while reducing future inspection needs. Strengthening existing bridges is challenging due to uneven component life and sensitivity to added weight. The project achieved a significant capacity increase conservatively.
