Roman bridge finally bypassed after nineteen centuries

Òn the main road from Lisbon between Ponte de Sôr and Alter do Chão there is a Roman bridge over the Ribeira da Seda dating from the second century. It has been in continual use ever since and has carried generations of traffic until it was deemed recently unsafe for heavy good vehicles. For the last four years all lorries have had to divert via Avis which adds nearly 50 km to the journey while cars continued to cross sturdy granite blocks that form the road surface in single file. Now, driving up for vintage I find the bridge has been bypassed by a new concrete flyover which has been under construction for the last year or so. It doesn’t feel nearly as solid as the Roman bridge and I am sure it won’t be in use nineteen centuries hence but it does cut about five minutes off the journey!
