High Speed Railway Bridge over AP7, Llinars del Valles

About

The Llinars Bridge this bridge is the first steel structure in the high-speed railway (HSR) joining Barcelona and the French Border. The 1,883-foot-long (574 m) Llinars HSR bridge comprises two parts: a 1,008-foot-long (307 m) composite steel–concrete structure crossing Autopista AP-7, and a continuous prestressed concrete bridge crossing the Mogent River with a maximum span of 157 feet (48 m). After analyzing many possible color combinations for the Llinars bridge, the designers selected blue for the members above the deck level and gray for the bottom of the longitudinal beams. This combination was intended to make the structure appear more slender.
