Now that Tallbridgeguy has sadly retired, it's good to discover more bridges blogs out there.
I've added Life, On a Bridged to the list of blogs on the Happy Pontist's main page. Based in Connecticut, USA, it offers some very interesting reports on bridges in that area and beyond.
I haven't added Bridgewright to my main page as it seems to cross my areas of interest so obliquely, but it is still well worth a look. It's by a specialist in traditional bridge carpentry.
