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.

The location of the piers was dictated by the highly skewed angle of the highway crossing and by the launching process used to erect the bridge.

To avoid interfering with the operation of Barcelona’s critically important tollway, incremental launching construction methods were used for the composite steel and concrete section.

The suspension members have a typical box girder cross section with an average depth of 1.7 m (5 ft 7 in).

For aesthetic reasons, the members have a radius of curvature of 48.6 m (159 ft), limiting the large structure’s vertical clearance over the highway and diminishing its visual obtrusiveness.
