Iowa-based bridge construction company, A.M. Cohron of Atlantic, Iowa, pulled off an amazing bridge teardown and rebuild job earlier this month. The bridge, located in West Des Moines, had been built in the 1940s and was due for a replacement. With little information available about the specs of the bridge, they set out to remove the bridge and construct a new one without disrupting train schedules.
Logistics Behind the Installation
For A.M. Cohron to successfully achieve their goal, they had to teardown the old bridge and erect the new bridge all within a 12-hour window. Due to the time constraint, they spent weeks in advance building the new bridge only 500 feet from the existing one. When the new 114-foot bridge was fully assembled, they got to work. They started the day at 6:30 am by carefully removing the old bridge which took until about 8:30 am. They then spent until about 3:00 pm prepping the foundation for the new bridge by drilling anchor bolt holes and installing concrete riser blocks. The new bridge was finally set upon its foundation at 5:00 pm and was fully complete for functional use by 9:00 pm.
RTL Equipment Construction Cranes Used
To complete this impressive job, A.M. Cohron needed some heavy crane rentals to make sure that the old bridge and new bridge could be lifted without issues. RTL Equipment was more than happy to rent our Iowa associates two crawler cranes to complete the job. They used a Kobelco CK1600G Lattice Boom Crawler Crane and a Terex HC275 Lattice Boom Crawler Crane to complete the tasks. Current A.M. Cohron’s Chairman, Keith Harlan, stated, “It was the largest two-crane pick up our company has done, with some pretty large cranes.” RTL Equipment is honored to be able to have helped with this successful and quick operation while supporting another Iowa company.
