A section of Siza's bridge lowers when it rains. Workers frequently zip back and forth between Siza's and Grimshaw's buildings carrying materials on small trolleys and the bridge acts as a roof. This images shows the tracks along which the bridge section slides down the concrete wall. The hole in the underside of the bridge funnels water into the post below so it doesn't drain off the sides and get swept up by the wind and splashed onto workers.
