Structural steel and precast concrete bridge construction: Precast post-tensioned concrete modular, tied cantilevered arch section bridge piers, described as V-piers, support structural steel bridge stringers/girders/beams. Sloped concrete arch sections consist of hollow field-precast reinforced concrete segments tied together by post-tensioned steel cables. Outward thrust of arch sections is supported by post-tensioned horizontal precast reinforced concrete tension tie beams. Woodrow Wilson Bridge replacement, Potomac River between Virginia and Maryland, Capitol Beltway, I-95/I-495. November 2006.
