The Autovía A-66 is a major highway in western Spain, part of the European route E803. The road is an upgrade of the N-630 which is being undertaken section by section. The route roughly corresponds to the ancient Roman 'Silver Route' connecting the cities of Mérida and Astorga. The final section of road south of Benavente is under construction as of October 2013 with completion anticipated in 2015.[needs update] From Wikipedia
