Rotterdam elevated metro -- Viaduct extension of city tunnel section
How 2650-m long concrete viaduct was built of prestressed concrete columns on piled foundations with five prestressed concrete beams spanning between prestressed concrete capping slabs; columns are cast in situ together with massive capping slabs, but beams are precast in specially built factory where they are prestressed by Polensky and Zollner system; using rapid hardening cement, half stress is applied after 18 to 24 hr and full stress at 50 hr; all 375 longitudinal beams are identical, 33 m long and 1.56 m deep, each weighing 66 tons; most of piers are 48 m center to center, shorter spans being obtained by reducing size of capping slab.
