Congestion

If I-70 through the Rockies is North America’s most physically dangerous freight corridor, then I-95 through the Northeast Corridor is its most psychologically punishing. The approximately 450-mile stretch from Washington, DC to Boston passes through the densest concentration of population, traffic, toll infrastructure, and aggressive drivers anywhere on the continent. For commercial truckers, running the Northeast Corridor means navigating a continuous gauntlet of merging traffic, narrow lanes, low-clearance bridges, construction zones, and toll plazas — often in stop-and-go conditions that last for hours.

Texas has more interstate highway miles than any other US state, and its urban interstates collectively account for a disproportionate share of the country’s highway fatalities. Among Texas interstates, I-45 stands out. The 286-mile corridor connecting Dallas to Galveston passes directly through the heart of Houston, and the Houston metropolitan sections of I-45 have generated fatality counts that put them among the most dangerous urban highway stretches in the nation.

Highway 401 through southern Ontario is, by vehicle count, the busiest highway in North America — and arguably the world. At its widest point through Toronto, the 401 carries over 400,000 vehicles per day across up to 18 lanes of traffic. For commercial truck drivers, this corridor is the backbone of Canadian freight: virtually all goods moving between Windsor (and the US border at Detroit), Toronto, Montreal, and the Maritime provinces travel this route.
