Abstract :
The Million Dollar Bridge carries the Copper River Highway across the Copper River, near Cordova, Alaska. The bridge was built in 1909–1910 to carry the Copper River and Northwestern Railway. It was badly damaged in the Prince William Sound earthquake of March 27, 1964. It was listed on the National Register of Historic Places on March 31, 2000.
This paper describes the nonlinear time history analysis made in support of the seismic retrofit of the bridge. The retrofit includes the installation of friction pendulum isolation bearings and replacement of the damaged Pier 3 with a new pier founded on a new pile foundation.
