Reply to "Maximum bridge length without center support"

Interesting. The arched span seems to be an adaptable design to most any length. The O'Callaghan Tillman bridge across the Colorado river at the Hoover Dam is an arch structure, but cable stays were used during the construction. Apparently adding superstructure and cables adds a lot of strength.

During Construction.

2006 picture as the arches start to form. Note the towers and the first of many cable stays until the complete arches are formed.
