Did that drive two years ago with my son, he transferred to Anchorage. We are a bit of adventurers, traveled a bit further west into British Columbia after entering Canada at Port of Entry North Dakota. We wanted to avoid the often traveled Alaska Highway, heading West past Edmonton to 37 North -

It's all paved, depending on the time of year several gas station stops open (we went in October). Its a rather lonely road rarely coming accross any other cars, which we found nice. On the North end about 450 miles up, you end at the Alaska Highway. After we entered Alaska, we headed to Fairbanks, just to say we seen it, hoping to enjoy the aurora's, too cloudy though, stayed the night then headed South to Anchorage on the Route 3 highway -

Total distance from Northern IL was about 3,700 miles, six days, within that time we made a few scenic stops. Hotels were easy to find, we never had a set destination day to day, when it got to around 4 pm each day we would look for a place down the road to call ahead for a room. Get the Rand McNally road map, over the air internet and phone service is limited, GPS will drop in and out, however when you enter a town you can usually pick up service and gain internet access. We always made sure we maintainted no less than quarter tank of gas and kept a two gallon can on the roof rack overhead just in case, of which we did tap into at one point. Canada does not take american currency, credit cards were not a problem, we used Amex, they always adjusted for the exchange rate with no surcharge. FYI, Watch your speed, 100 kph is strictly enforced. Passports required!
Once we reached Anchorage, found my son's apartment and off loaded his possessions, we got up the next morning and traveled South to Seward, one cool stop was to visit Exit Glacier -

Be Safe my friend and enjoy the trip!
