Two more of the 19 crossings over the 30-mi. stormwater diversion channel opened to traffic. That bridge work involved placing 500 bridge girders and 28,000 cu. yds. of concrete, which is enough to fill 3.5 Goodyear blimps.
The County Road 22 crossing opened in early March, and work continued nearby with removing those bypass lanes.
West of the Fargo-Moorhead metro area and north of I-94, BNSF crews completed track and ballast work as well as mainline track tie-ins for westbound rail traffic at the KO crossing. Westbound trains were permanently rerouted over the completed channel crossing on March 18 and the eastbound lane opened at the end of March.
Additionally, ASN Constructors completed the last concrete placement for the 19 channel crossings. With the concrete railings now placed, the 52nd Avenue West bridge is one step closer to opening this year along with County Roads 6 and 14 — the last of the project's 19 bridges.
Beyond crossings, ASN Constructors assembled and installed the horizontal truss segment of the Maple River Aqueduct's vertical lift gate support structure. Much like the gated control structures to the south, the gate will operate to regulate river flows during times of extreme flood risk.
