BNSF Train Bridge Replacement Progress 11-17-2024 ( Video 9 )
With Fall reaching an end and Winter slowly gripping the Northern Plains, construction at the new BNSF Railroad Bridge in Bismarck, ND is reaching an end for the 2024 construction season. Soon the Missouri River will freeze over and be covered with a layer of ice several feet thick. (These conditions will last until mid-April and possibly into early May.) Once the river is completely has thawed in the Spring the 2025 phase of the BNSF Bridge construction project will resume in full swing. The next phase will highlight the completion of the West side piers and infrastructure and potential tie-in of the completed East end work. This project is estimated to be complete sometime in 2026. The current bridge is a single rail / truss design system, the new bridge will be dual rail with no trusses, offering higher efficiency and capacity for all rail travel along the BNSF corridor.
Currently, crews at the BNSF Railway bridge over the Missouri River at Bismarck and Mandan continue working around the clock on Pier 7 in the river. Double shifts are being utilized to pump river bottom material out of the cofferdam, which must be completed before pile can be driven. To keep construction on schedule and remove the cofferdam in time this winter, crews will be pile driving at night, likely beginning later this month, through completion of the pile driving at Pier 7.
Trucks hauling material for the embankment on the west side are nearing completion for this season. About 65% complete, the embankment will require some additional material to bring it up to the needed elevation for hosting the new railroad track. The majority of the remaining embankment will be placed in 2027.
Other progress includes the completion of Abutment 1 and Piers 2 and 3 on the east side. Pier 9 is the furthest along of the piers on the west side. The pile are driven, the footing and the lower portion of the stem have been poured. Pier 8 pile driving is almost complete, and Pier 7 work is ongoing as mentioned. Similar to last winter, crews will work at the project site as long as weather allows and then break for winter. In the spring, depending on weather, work will resume and focus on the east side of the project. Pier 4, at the edge of River Road, along with Piers 5 and 6 in the river, will be constructed in 2025.
BNSF continues to appreciate the collaboration with local agencies and the community as we build a new bridge that will serve our customers and the state for another 100 years.
