As detailed, the first phase corresponds to the sheeting works. The Department of Road Infrastructure started drafting the comprehensive restoration project for the entire viaduct two years ago, “nevertheless, the studies carried out for this design have shown the need for shoring work prior to the Urumea section, as the bridge was built in 1972 and at some points traffic and estuary erosion have caused significant deterioration,” he said.
