Dangerous Highways

Interstate 75 is one of the longest north-south interstates in the United States, running approximately 1,786 miles from Sault Ste. Marie, Michigan, at the Canadian border to Hialeah, Florida, near Miami. For commercial drivers, I-75 is a primary artery connecting the Midwest manufacturing belt and Great Lakes region to Florida’s population centers and Gulf ports. The full length of the route is demanding, but two sections in particular — Florida and Georgia — concentrate the corridor’s most acute dangers.

The Queen Elizabeth Way — the QEW — is the primary expressway connecting Toronto, the western Greater Toronto Area, Hamilton, and the Niagara region. It is one of the busiest commercial vehicle corridors in Ontario, carrying massive freight volumes between Toronto’s distribution infrastructure and the US border at Niagara Falls and Fort Erie. Somewhere near the middle of this corridor, between the cities of Burlington and Hamilton, sits a structure that concentrates the QEW’s inherent dangers into their most intense form: the Burlington Skyway.

US Highway 17 is not a highway that appears on most national dangerous-road lists. It lacks the dramatic mountain passes of I-70 or the oilfield chaos of US-285. It is, in most sections, a moderately traveled two-lane or four-lane road through the coastal South — passing through resort towns, fishing villages, agricultural land, and coastal wetlands from Virginia to Florida. That ordinariness is part of what makes it dangerous.

The highway’s accident rate reflects a confluence of hazards that individually seem manageable but in combination produce consistent, serious crashes: poor infrastructure, varied and unpredictable traffic, inadequate lighting, and terrain that limits sight distances in ways that drivers unfamiliar with the route don’t anticipate.

Interstate 84 is the primary east-west freight corridor through Oregon and Idaho, following the Columbia River gorge before turning south through the high desert toward Boise and Salt Lake City. Most of this route is straightforward for experienced commercial drivers — until the highway climbs into the Blue Mountains east of Pendleton.

At the summit of what truckers call Cabbage Hill (the locals’ name for the Emigrant Hill section of I-84), the road crests above 4,000 feet before dropping dramatically toward the Umatilla River valley and Pendleton below. What follows is one of the most consequential descents on any US interstate.

Colorado sits at the intersection of two of the highest transcontinental freight routes in North America: I-70 crossing the Continental Divide at the Eisenhower Tunnel, and US-160 serving the southwestern corner of the state. Both routes have sections that force trucks onto some of the most demanding roads in commercial driving — roads that make the already-challenging main corridors look mild by comparison.

This article covers two of those routes: Loveland Pass (US-6) and Wolf Creek Pass (US-160).

Michigan’s roads have a national reputation that has transcended trucking circles into popular culture. The state’s infrastructure funding shortfall, combined with one of the most punishing freeze-thaw climates in the contiguous United States, has produced a highway network that truckers and civilians alike recognize immediately. “Michigan, Michigan, and Michigan is pretty bad too.” “I75 in Michigan heading towards Detroit is an abomination.” One trucker reported getting motion sickness from the sustained bouncing on a Michigan interstate. This is the road.

Northwestern Ontario is one of the most sparsely populated regions in Canada. The vast boreal forest between the Manitoba border and Thunder Bay is crossed by a thin ribbon of highway — Highway 17, the main surface route through the region and part of the Trans-Canada Highway system. The approximately 200-kilometre section between Kenora and Dryden distills everything that makes northern Ontario highway driving difficult: long distances, no services, dense wildlife, severe winters, and the particular hazard of fatigue that sets in when hours pass with no town, no fuel stop, and no change in scenery.
