In the aftermath of the collapse of the 40-year-old Minneapolis (MN) I-35W bridge on August 1, U.S. Secretary of Transportation Mary E. Peters has asked states to carefully consider the additional weight that might be placed on bridges during construction or repair projects. The National Transportation Safety Board (NTSB) has indicated that the gusset plates on the bridge may have been a factor in the collapse and that the weight of construction equipment and materials on the bridge may have been a source of stress, Peters said in a news release. She said she would immediately share with states information obtained through the NTSB investigation. The bridge, constructed in 1967, was built with a single 458-foot-long steel arch. Peters has also asked that all states immediately inspect any steel-deck truss bridges similar to the Minneapolis bridge.
