World's longest tunnel pageOur old friends Gunnar Lotsberg and Eugenio Merzagora have been revising and updating WLTP, our companion website, and seem to have finally nailed every operating tunnel in the Universe. For those who don't know, tunnelbuilder.com and its two language sites follow tunnels under construction, and WLTP catalogues them upon completion, adding any missing detail before installing them into their amazing database. Obviously, we need to catch these guys out as often as possible to keep them on their toes. So, next time you drive through tunnel country and need something to keep the kids quiet in the back seat, get them to take notes of the tunnel names and lengths on each highway. They can compare their observations with WLTP, SatNav and Google Earth, and notify any errors to eugenio.merzagora@libero.it. 22/09.
