1-74 MISSISSIPPI RIVER BRIDGE

摘要

From ice to rising river levels in 2018 and 2019, working in the Mississippi has been challenging. Construction workers hop onto crew boats each day to get to the work sites, and contractors rely on barges to deliver project equipment and materials such as cranes and concrete. With extraordinary effort and patience, crews have been working through all types of weather to make the new bridge a reality. With the Mississippi River at a major flood stage for 45 days and counting, as well as water levels hitting a record 22.7 ft in May 2019, the high water and swift current have created additional challenges and safety concerns. Certain tasks in the river have been placed on hold for the safety of workers while the contractor focuses on tasks above water level such as decking the westbound bridge and bolting arch segments.
