Here's one I'm considering building. It's the Pacific Electric Torrance bridge, located across Torrance Blvd. just West of Western Avenue. Two tracks used to run under it and a switch was actually on the deck. The lower track switched off to the south past the PE Torrance Depot (now "The Depot" Restaurant) onto the remnants of the PE Torrance-to-San Pedro branch and climbed past a switch. Trains (first PE, then SP) would then back onto the bridge toward the Armco Steel plant that used to be to the North. The loads in were typically coal. The PE Torrance shops were located Northwest of the bridge and the tracks leading there are still in service, albeit rare.
The City of Torrance features the bridge in their seal. Several years back, the City put out a request for proposals/bids on doing a structural rehab on the bridge. The RFP included a full set of drawings and dimensions which I downloaded.
