Golden Gate Bridge, suspension bridge spanning the Golden Gate in California to link San Francisco with Marin county to the north. The first and second phases of the retrofit targeted the Marin Viaduct (the bridge’s north approach) and the Fort Point Arch respectively. The modification of the Golden Gate Bridge railing is the most recent and most audible element of a multi-phase retrofit that has been underway since 1997. Even this seemingly minor modification, when extrapolated across the length of the bridge, would have significant structural benefits: The new railing decreases the exposed surface area by thousands of square feet, meaning a likely reduction of hundreds of thousands of pounds of lateral wind loading. Had to look that one up. I ran downstairs to turn on my laptop to find a picture of the golden gate bridge, and maybe google map a white mansion somewhere on the coast of San Francisco.
