A viaduct expressway structure combined with underground utilities
Viaduct Structure Description
  • Steel viaduct bridge:

    A 6,800m long and 20~26m wide structure with 4~6 traffic lanes and 6 ramps.

  • Underground car-parking lots:

    8 underground parking lots are able to provide 2,370 parking units beneath the viaduct structure.

  • Underground shopping mall and street:

    A two-story R.C. structure beneath the ground provides a 830m long and 37m wide space. The first floor is for an underground shopping mall and street level to facilitate a joint development with the Taipei Main Railway Station, rapid transit interchange and bus terminal, and the second floor is for an underground car-parking lot.

After seven years of construction, Taipei's first East-West Expressway (Civic Boulevard), extending from the western part of the city at the intersection of the Chung Hsiao Bridge and Hua-nan Expressway viaduct, to the eastern part of the city at a connection with Keelung Road, was opened to traffic at the end of 1997. The expressway runs directly above the existing Taiwan Railway Administration (TRA) railway and is part of a viaduct structure which is combined with numerous underground facilities, including shopping malls, parking lots, common duct utilities, etc.

While promoting the concept of urban integration in the context of Taipei, CECI was honored for its planning and detailed design of the project by winning the distinguished award of "Structural Engineering Technology Honor" from the Chinese Society of Structure Engineering.

The aim of the project achieved the following goals:

  • To provide a faster journey and improved accessibility between Taipei's central area and its suburban neighborhoods, facilitate direct connections between the surrounding areas, and enhance the efficiency of traffic during rush hour.
  • To implement a new east-west direction elevated viaduct expressway not only to yield an effective way to optimize Taipei's vehicular flow, but also to create more space for commercial land use and car-parking.
