Mattole Road Bridge
Posted January 3, 2018, by laura cooskey (mattolehistory [at] frontiernet [dot] net)

Good entry and information. Only thing is that the bridge was completed in 1923. I don't know why all the official information says 1935. I have a photo of tow-headed little kids born in the 1910s posing next to it when it was brand-new. Buck Miner (born 1925) said it was there when he was born. The new road on the north side of the Mattole River, replacing the Gardner Grade, was opened in 1923, when the two bridges across the Mattole were completed: the suspension bridge at Shields' Ford (just upstream from present Elwyn Lindley bridge) and the Concrete Arch bridge just upstream of present A.Way Park.

Thanks for letting me set the record straight.
