The bridge was the southeastern boundary of the . Immediately upstream is the lock and dam at Saint Anthony Falls, where Minneapolis began. The first bridge upstream is the historic Stone Arch Bridge, built for the Great Northern Railway and now used for bicycle and pedestrian traffic. The south abutment was in an area polluted by a coal gas processing plant.
The construction contracts, worth in total more than US$5. Hurcon Inc. Construction on the bridge began in 1. The three main spans were of deck truss construction while all but two of the eleven approach spans were steel multi- girder construction, the two exceptions being concrete slab construction. The piers were not built in the navigation channel; instead, the center span of the bridge consisted of a single 4. The two support piers for the main trusses, each with two load- bearing concrete pylons at either side of the center main span, were located on opposite banks of the river. Each was 2. 66 feet (8. At the top of the main trusses were the deck trusses, 1.
These deck beams supported longitudinal deck stringers 2. It had transverse expansion joints at the centers and ends of each of the three main spans. Vehicles coming across the bridge experienced black ice and there was a major pile- up on the bridge on the northbound side.

The main trusses connected to these cross girders and resistance to motion at the connection point bearings was leading to unanticipated out- of- plane distortion of the cross girders and subsequent stress cracking. The situation was addressed prior to the study by drilling the cracks to prevent further propagation. The report also noted a concern about lack of redundancy in the main truss system, which meant the bridge had a greater risk of collapse in the event of any single structural failure.
Although the report concluded that the bridge should not have any problems with fatigue cracking in the foreseeable future, regular inspection, structural health monitoring, and use of strain gauges had been suggested. Department of Transportation's. National Bridge Inventory database. Bridge inspectors use a sufficiency rating that ranges from the highest score, 1.

State law has limits that may limit awards to below that amount. No legislative action was needed for this step.
Minneapolis and Hennepin County received mutual aid from neighboring cities and counties throughout the metropolitan area. They took 8. 1 minutes to triage and transport 1.

By the next morning, they had shifted their focus to the recovery of bodies, with several vehicles known to be trapped under the debris and several people still unaccounted for. Twenty divers organized by the Hennepin County Sheriff's Office (HCSO) used side- scan sonar to locate vehicles submerged in the murky water. Their efforts were hampered by debris and challenging currents.
The United States Army Corps of Engineers (USACE) lowered the river level by two feet (6. Ford Dam to allow easier access to vehicles in the water. The Minneapolis Police Department (MPD) secured the area, MFD managed the ground operations, and HCSO was in charge of the water operation.

The Board, with assistance from the FHWA, conducted a thorough review of the design of the bridge, with an emphasis on the design of the gusset plates. This review discovered that the original design process of the I- 3. W bridge led to a serious error in sizing some of the gusset plates in the main truss. The investigation revealed that photos from a June 2.
