Travelling without advanced knowledge of the terrain can be dangerous. Although many other routes are traveled everyday, they are also dangerous. There are other factors to consider when travelling commonly used transportation routes.
Before we consider these factors lets consider some of the most highways in the World.
Please note this a very subjective list and may be on more treacherous routes base don you own ideas and experiences.
Most Dangerous Roads In The World
Las 5 Carrentas mas Traicioneras y Extremas del Mundo
The 5 Most treacherous and Extreme Roads in The World
North Yungas Road Bolivia
This road links La Paz, the capital of Bolivia, with Coroico, also in Bolvia. Some places on this route there a sheer drops of 1000 feet.Every year hundreds of deaths are recorded as vehicles try to pass other vehicles.
Zojila Pass, India
Zojila is a high mountain pass in Indian Kashmir, located on the Indian National Highway 1D between Srinagar and Leh. Most of the Himalayan roads are extremely hazardous but this one is a killer.
Dangerously narrow and often muddy or icy, it is littered with crashed cars and overturned buses. This pass is often closed during the winter.
Most Amazing Roads in The World You Should Drive
Most Dangerous Roads I Have Traveled
Travelling Safely In Mountainous Regions
1. Paso International Los Libertadores
Los Libertadores International Pass
This is a mountain pass in the Andes Mountain connecting the capital city of Santiago in Chile to Mendoza in Argentina. This pass is a major trucking route. When when we drove this pass the weather was warm and there was no snow. The surrounding mountains were quit steep.
The numerous switchbacks in the road helped to reduce the grade and limit the overheating of my breaks and engine during the descent. There were many areas to pull over, although i do not no how well these areas are maintained in the winter time.. This mountain pass consists of many switchbacks and reaches over 10,000 feet. At the top is a ski resort. Los Libertadores International Pass is very near the trail head of the highest mountain in the Andes and the America's, Aconcagua (Spanish pronunciation: [akoŋˈkaɣwa]).
From this pass you cannot see Aconcagua as the mountains in near it are also over 10,000 feet. To get to the trail head of Aconcaua you will have enter Argentina via The Los Libertadores International Pass for Chilean side of the boarder.
There a number of proposed tunnel routes
that are being considered to bypass this mountain route. One such tunnel will be 52 kilometers long and will use train travel as well as trucks( trucks will board trains at certain transportation links). There is a excellent model of this in the Santiago International airport I have viewed in 2013, However I do not know if this model still exists and how much the project has changed or been completed.
Extreme Tunnel Planned For Andes Rail Link
This will be an amazing civil engineering project.
Anyway here is some photos of the pass.
Winter
Summer
2. This switchback road is near the boarder of Utah and Arizona.
There were no guard rials on this route and no warning until you arrived at the start of the decline.
3. Highway 401- Ontario Canada
You have a greater chance of being involved in a car accident if you are driving on Highway 401 between Whites Rd. in Pickering and Courtice Rd. east of Oshawa than any other highway location in the province, according to Ontario Provincial Police data obtained by the Toronto Star. From Top 12 Most Dangerous Highways In Canada Website.
This has to one of the most scariest highways I have ever driven, both in winter and summer. The most dangerous is considered, in my opinion, is the northern most section of over 240 kms from Grassland to Fort McMurray's mining infrastructure (Suncor and Syncrude)
There are no mountain passes and switch back, but some of the driver are suicidal There is are no settlements between wandering river and Fort McMurray and it will be a long wait for the police and EMS if you get into an accident. An there were many fatal accidents in the past involving head on collisions as a result of vehicles trying to pass to many cars and trucks at once.
Also some of the largest pieces of mining equipment in the world get transported on this highway. Thankfully this highway is now completely twined (the work was completed in 2016). Still this road often sees -40 degrees C and heavy snow and is still in the middle of nowhere.
Despite relatively low traffic volumes compared to other major highways in the province, the route has earned the moniker "Highway of Death" due to many fatal crashes.
Between 2001 and 2005, over 1,000 crashes occurred on Highway 63 in which 25 people were killed and 257 others were injured
Advanced Knowledge of The Climate and Terrain of The Road You About To Travel Save Your Life
The purpose of this information is not discourage them taking these routes, but to inform them of the conditions they could or will encounter.
Steep grades with long narrow winding roads can cause your breaks to over heat and fail!!! Your breaks will become read hot.
I have experience this going over a mountain pass just west of Death valley in the Panamint Range (northern eastern reach of the Mojave Desert). This was no joke. The grade was not severe, but is was long decline and there were no run away truck ramps. Which reminds me that the worse places to lose your breaks is in the Appalachians Mountains (although there is good place to lose your breaks. - be sure your breaks are in good condition and stop to let your breaks to cool off - rest stops are there for a reason to rest and let your engine and breaks to cool off.
When your breaks fail going down a steep grade you miss the turn or roll over on a sharp turn only meant for 15 miles per hour.
