This design-build project replaced the existing U.S. 69 Missouri River Bridge with a four-lane 2,155-ft bridge composed of a 1,350-ft continuous steel girder unit and an 805-ft prestressed concrete girder unit. It was one of several bridge replacements along the Missouri River. 

The safety plan included daily foreman safety huddles and management observations; weekly project tool box talks, project meetings with the Missouri DOT, safety observation walks and foreman and supervisor discussions; a quarterly corporate safety audit; and insurance safety audits. The American Bridge/Garver (AB/G) team removed and replaced the existing crossing in Riverside, Mo. The project required a new river crossing with four 12-foot lanes, a shared use path, improvements to two intersections and maintenance of traffic during replacement.

Various safety indicators were established at the project’s outset, and the team monitored its compliance on a monthly basis. The team self-assessed a monetary penalty and offered a deductive change order in the amount of the penalty if 100% compliance was not obtained during the month. Lagging indicators were monitored monthly.

The program was successful in that no penalties were collected. Crews completed 169,800 work-hours with no lost-time accidents and no recordable incidents.
