A post-tensioned design used in conjunction with engineered backfill
enabled reuse of the US-24 bridge’s existing abutments in Dearborn. Rarely used for
bridge rehabilitations, the approach generated cost savings, kept construction activities out
of the river below, and shaved three months off the Michigan Department of
Transportation’s construction schedule. The project has been recognized by the American Council of
Engineering Companies and the Michigan Construction Quality Partnership.
