Bridge Safety: Structural Soundness of the Zilwaukee Bridge

In response to a congressional request, GAO reviewed the Zilwaukee Bridge Project to: (1) determine whether the testing program that the Michigan Department of Transportation (MDOT) implemented confirmed that the bridge was structurally sound; (2) identify construction problems causing concerns about the bridge and determine whether they would affect its ability to perform as designed; and (3) assess the MDOT draft bridge maintenance manual.
