FARGO, ND (August 23, 2024) - This month, ASN Constructors surpassed the halfway point of excavating the 30-mile-long stormwater diversion channel for the FM Area Diversion project. The channel, which is being constructed through a public-private partnership with the Red River Valley Alliance, will safely move floodwaters around the Fargo-Moorhead metro area in times of significant flooding. Of the 45 million cubic yards that ASN will excavate, 23.5 million cubic yards have now been moved. For perspective, that's enough earth to construct seven-and-a-half full-size replicas of the Great Pyramid of Giza.
"We have reached an exciting milestone with half of the stormwater diversion channel excavation now being complete," said Pedro Martinez, project director for ASN Constructors. "ASN Constructors is proud of the work we are doing for the communities we live and work in, and this milestone brings all of us one step closer to permanent, reliable flood protection. Work has been ongoing day and night, nearly 365 days a year, to get to this point, and we are committed to continuing our work to finish the channel and associated structures."
Views of the excavation on Reach 13 of the channel can be seen in this month's video overview, which is at https://youtu.be/9uWLR_Zht_I, along with other recent construction activity.
Channel Crossings: All 19 road and railroad crossings that comprise the P3 portion of the project are under construction. At County Road 4 and 31, ASN Constructors poured the bridge deck for the combined crossing. Just north of the metro area, at the I-29 crossing, they worked on forming the bridge abutments and piers, and they also installed girders at one of the pair of interstate crossings. Excavation for the County Road 81 crossing also is underway. For rail line crossings, ASN built bridge piers and began constructing the abutments for the new line at BNSF Prosper. They also excavated at the BNSF Hillsboro crossing site.
Inlets: In addition to the 19 road and railroad bridges, ASN Constructors is building nine maintenance road bridges. The first, at the Lower Rush River Inlet site, now has the substructure elements completed and the bridge girders installed.
Red River Structure: The first gate is up at the largest of three control structures, and components for the second of three 50-by-52.5-foot radial-arm gates are being delivered. The contractor at the site also completed preload embankments on the east and west sides of the structure. They've begun driving sheet piles and h-piles for the eastside floodwall, and they are building concrete gage well structures that will house instrumentation for measuring the water surface level both up- and downstream of the structure when the project operates.
Southern Embankment: Earthwork continues on the 22-mile-long southern embankment where there U.S. Army Corps of Engineers contractor is installing the first precast concrete box culvert segments where the borrow ditch will cross County Road 16.
