potash (mainly to Minnesota), cement, livestock, clothing, furniture, grain, metal products, frozen french fries (to Mexico), and meat, much of which moves in truckload quantities. Southbound livestock movements are primarily destined for Dakota City, Sioux Falls, and Des Moines, Iowa. Roughly 10 percent of the southbound trucks are empty. Northbound commodities are dominated by fresh produce primarily originating in the southern United States, much of which is handled by North Dakota-based produce haulers. Roughly 30 to 40 percent of the northbound trucks are empty. Two-thirds of the northbound movements through this crossing are conducted by Canadian-registered vehicles. Roughly 50 percent of the northbound trucks are Manitoba carriers with the remainder primarily based in North Dakota, Minnesota, Wisconsin, and Ohio.
Truck characteristics at this crossing are primarily controlled by U.S. regulations, and in particular, those of North Dakota, Minnesota, States south, and the Federal law. Being on the I- 29, this crossing is subject to the ISTEA freeze of 105,500 pounds GVW and 103-foot cargo- carrying unit length for tractor double-trailer combinations.
Roughly 90 percent of the trucks using this crossing are tractor-semitrailers, primarily with five- axles. These vehicles and their loadings are being primarily controlled by the U.S. Federal weight limits of 80,000 pounds GVW, 20,000 and 34,000 pounds on single and tandem axles respectively, and Bridge Formula B. This is because much of this traffic travels on the I-94 east of Fargo, North Dakota into Minnesota, and beyond. Other larger configurations moving through this crossing (for example, six axle tractor-semitrailers and seven-axle doubles) are routed to the South and West. Customs officers advise that rail traffic across the Manitoba-Minnesota border to the east has been relatively steady, whereas truck traffic has been growing rapidly.

Findings of interest from this report are: (1) Tractor-semitrailer combinations accounted for 85 percent of the vehicles surveyed, tractor-double trailers 7 percent, straight trucks 6 percent, truck trailers 1 percent, and deadhead tractors 1 percent; (2) 75 percent of trucks were for-hire and 25 percent were private; (3) 40 percent of the northbound and 35 percent of the southbound trucks were empty, and (4) origin-destination patterns for tractor-semitrailer combinations are shown in Table 4-3-a [derived from Tables A.2.3.d and A.2.3.e].
