Hugh "the Polar Bear" Rowland returns to Alaska at last and has to face down his haul road nemesis: chaining up. Meanwhile, failing trailer brakes and trash talk over the CB threaten to derail Lisa's comeback.

Ice Road Truckers venture 200 miles north of the Arctic Circle, transporting 10,000 loads of vital materials, over a highway made entirely of ice onto the Arctic Ocean.

The end of the line is here. The Polar drivers face the long, difficult journey back down the world's longest seasonal winter road. Lisa has to make a game-changing decision...help a competitor push further into the arctic unknown or stick with her teammates and convoy back to Polar headquarters. Her decision could be costly as conditions quickly deteriorate.

It's the second week of the ice road season and the brutal temperatures of -40 degrees are already taking their toll on the truckers.

In one of the coldest frontiers on earth, road construction crews begin the process of creating the most unique passage in the world---a 350-mile highway of ice.

The rivalry heats up between Ice Road Truckers veteran Hugh Rowland and his employee Rick Yemm as they compete for the highest load count.

The Ice Road Truckers race for the last of the cash as they travel across thinning ice.

It's the 18th day of the ice road season and truckers have delivered more than 3000 loads to the diamond mines, but they still have 7000 more to go. The temperatures are dropping, the loads are getting heavier and the ice is just three feet thick.

It's half way through the grueling ice road season. Six hundred truckers have ferried more than 4,000 loads to the northern mines. They still have 6,000 left to go, but everyday roadblocks threaten their progress.

Jay Westgard embarks on a trip to the De Beers mine with the heaviest and most valuable piece of equipment this season.

A volatile season is winding down and it seems like trouble comes in doubles. Lisa Kelly and Steph Custance barely get by when they team up for safe passage on the icy terrain. Art Burke takes on a two-fer, bringing a split load into the North Country, hoping this will be his last load of the year. And Polar owner Mark Kohaykewych gives Todd Dewey a job that might just be impossible: hauling a double oversized camp shack up the twisty, narrow road to the village of Big Trout. Can it be done? Todd doesn't think so!

In the Season 9 premiere, Darrell Ward attempts to poach a legendary rival driver from Polar Industries, which could spark an all-out war.

The war for ice road supremacy is heating up and Polar Industries is pushing their drivers to the absolute limit. Art Burke must cross one of the longest winter roads in the world. Polar's top driver, Todd Dewey, is forced to dig himself out of mountains of fresh snow or risk a dangerous night in freezing temperatures. Rival, Darrell Ward, takes a load over a newly opened road littered with abandoned trucks frozen in time.

The spring thaw is in full melt mode as the drivers get one last lick before the ice roads close for the season. Steph Custance is the first to experience nature's wrath as she slips and slides deep into the trees off a slick road. Meanwhile Todd Dewey is struggling with a big load of construction material over a long and twisty trail. Art Burke is not a happy camper when he is pressed into service to retrieve a super heavy bulldozer over a rapidly melting ice crossing. Reno Ward takes a risky final run just to have his truck die on the ice. And Lisa Kelly is heading home when she gets an emergency call to come to the rescue before it's too late.

Polar Industries goes for the record books, sending driver Todd on a risky run to deliver the heaviest load in company history. But will the weight prove to be too much on a tenuous ice crossing? Art is sent on a high stakes rescue mission and finds the job more than he bargained for. Lisa lands an exclusive contract over one of the wildest trails in Canada. Darrell steals a load from Polar, leading to a clash between him and Mark.

Darrell Ward and Lisa Kelly try to make good on a power play for their young company but could lose everything when Darrell's truck breaks down. Polar driver Todd Dewey must backtrack hundreds of miles to recover lost freight or risk losing a vital contract. Rookie Mike Simmons' inexperience costs him on one of Canada's toughest winter roads. And as trails and crossings continue to melt, Art Burke finds himself fighting for his life on the ice.

Day 1 of the new Ice Road season brings 6,000 loads of freight to move in just 12 weeks to the oil camps of Alaska's North Slope. From unexpected weather and treacherous terrain, this is by far the most death defying route to date.

Temperatures drop to 70 below as the race for big bucks heats up. Truckers Lisa Kelly faces hurdles, Jack Jesse deals with the perils of hauling a load of 130-foot pipe and rookie Tim Freeman struggles with challenging mechanical problems.

The clock is ticking and an arctic storm is brewing. Hugh and Alex embark on their first trip to Prudhoe Bay, Lisa Kelly requests her first ever "heavy haul," and Tim Freeman makes his second attempt to navigate the ice road.

A massive storm blows in and all traffic on the ice road comes to a standstill. George, Tim and Lisa take shelter at Coldfoot while Jack Jesse tries to outrun the storm.

Another winter storm causes a major collision on "Slope Mountain" and tow truck driver Ben Krsykowski must carefully pull a truck cab and trailer back up on the road--knowing that the slightest spark could set off a massive explosion.

Lisa Kelly auditions to be the first woman to break into the elite Heavy Haul division while Hugh "The Polar Bear" Rowland aims for the title: master of the all the North American ice roads.

The race is on to make it to Prudhoe before a wicked storm turns fierce. Despite a cloud of ice fog, Hugh and Phil make it through the worst of the storm and celebrate at the top of Atigun Pass.

Record snowfall mixed with now warmer temperatures has turned Atigun Pass into a devil's slide - slippery than ever and at an all time high for avalanche risk.

With just three weeks to go, everyone is pushing it to the limit to get the freight to Deadhorse before the season ends. Lisa convoys north with Jack Jesse while Tim and George are delayed in Fairbanks.
