ULMA takes part on the repairs to the longest viaduct in Lisbon

The Duarte Pacheco Viaduct is one of the main access roads to the city of Lisbon, and an outstanding example of 20th century architecture in Portugal. The work focused on three areas: seismic strengthening, structural repair and improvement and enhancement of the viaduct's safety conditions.
