Slaughter alley

Slaughter alley is a colloquial name given for sections of highway known for high rates of fatal traffic accidents.

Australia

 * Eyre Highway on the Nullarbor Plain in southern Australia is said to be the straightest, flattest road in the world. In this case it is the monotony of the straight, narrow road combined with long trucks (road trains, the air blast from which can cause car drivers to lose control) that present the hazard.

Canada
In 2009, the Canadian Automobile Association published a list of the most dangerous roads in Canada.
 * Between 2004 and 2009, the 400 km undivided stretch of Highway 63 in Alberta saw 22 deaths and more than 250 injuries. The remote highway is the main route to Fort McMurray and has seen extraordinary increases in traffic volume with accelerated development of the Alberta Oil Sands. Between 2003 and 2015, a total of 190 people have died on Highway 63 and Highway 881.

Israel

 * Highway 31 in southern Israel, 24 km between Sdom and Arad, is said to be pinned with obelisks for the dead. Other parts of the road are prone to fatal accidents due to a single lane in each direction and lack of separation between the lanes. The 31 km of the road had been declared as red road (a road that has more than average number of fatal accidents) by Or Yarok.

United States

 * "Killer 17" and "Blood Alley.": The four lane section of California State Route 17 has a combination of narrow lanes, dense traffic, slow trucks, sharp turns, blind curves, poor weather, sudden changes in traffic speeds, and wandering fauna such as deer, wild turkeys, and mountain lions, which has led to a number of collisions and fatalities. Because of this, SR 17 is considered to be one of the most dangerous highways in the state.
