Sichuan China's Bridges: Qixia Park Pedestrian Bridge in Chengdu (2)

July 2008 (30.654 Degrees, 104.051 Degrees) Qixia Park Pedestrian Bridge

A closer look at the Qixia Park Bridge. We can see that the arch is composed of three reinforced concrete ribs with diaphragms evenly spaced between them.  There are actually two decks with a longitudinal joint between them. Each deck is supported by two concrete girders just inside the arch ribs.

I think a common style for an Asian arch bridge is to have the deck swoop upward on top of the arch at midspan. This may no longer be a choice for U.S. bridges that are built to ADA standards.
