not sure if posted before but here's the oldest transporter bridge in the world (there are only 10 out of 20 ever built still operational) North of Bilbao
also happened to be the 700th anniversary of the founding of Portugalete on the West side when we were there last week
it's a paltry €0.50 to cross on foot (€0.90 by bike which we did) but there is still a little boat which does a great trade doing the same crossing for €0.45 which we also did
if you want to walk along the top it's €9.50
we didn't bother
