Great photo! I remember the bridge well. Crossed it at the end of day 28 of my walk last year, (Monday 5 May 2014), having walked from Rabanal del Camino - 26 km - that day. Stayed the night at Hostal El Palacio (on the right hand side immediately across the bridge). Friendly people, great food and cold beer in the bar downstairs. Walked on to Villafranca del Bierzo next day.
