DESIGN OF CONTINUOUS HIGHWAY BRIDGES WITH

2018-11-1  Los Penasquitos Bridge in California was a 1966 PCI award winner. A primary reason for using conti-nuity with precast, prestressed gird-ers is the elimination of the main-tenance costs associated with bridge deck joints and deck drainage onto the substructure. Continuity also im-proves the appearance and the riding qualities of this type of bridge.
