The viaduct has a precast central trapezoidal spine with precast side frame cantilevers stitched and transversally prestressed with the spine. The spines are match-cast and erected using an underslung launching girder, upon which line and levelling are carried out prior to gluing and prestressing. The side cantilevers are erected from the completed spine by the use of an overhead hanger system. The shaped piers and deck soffit are cast with a fine fluting creating an overall appearance of harmony and elegance.
