This is the last suspension bridge in Texas that you can drive across, built mostly by hand labor in 1939.
It spans the Colorado River between Goldthwaite and San Saba and is accessible by car on the (gravel) County Road 433.
The bridge's road surface is made of wood; the cables are made of hundreds of wires individually hand-carried across the river by workers (from the Austin Bridge Company of Dallas) and strung together to make the cables. A crew of a dozen men built the bridge, according to a Goldthwaite Eagle article from 1983.

Standing at midpoint of bridge: Colorado river, looking east. The bridge sways a bit in the wind, or when a car drives across. No one came across while I was up there.

The towers were made on-site in 1939 -- welded angle steel topped with cast steel saddles to support the cables (source: Goldthwaite Eagle, 1983)
