Hi.
I found a copy of a PDF file on my PC titled""Fire and Reconstruction at Lobato Bridge in New Mexico" by FREDERICK R. RUTZ, TODD M. RILEY, AND PETER FOSTER.
Not all the girders were replaced on the bridge. An excerpt from the report:
"The east girder of each span suffered more damage than the west girder, suggesting that prevailing winds from the west may have concentrated more heat on the east side. Spans 1 through 4 suffered irreparable damage; span 5 suffered damage to the top lateral bracing but was considered repairable; and span 6 had no apparent damage. At bents number 2 and 3, the bolts that connect the girders to the bearings were either sheared off or distorted."
FWIW.
