Ellensburg, WA to Yellowhead Hwy 16 Junction, BC
The Central Access Route is a meandering, mostly 2-lane road through Washington’s Okanogan valley and British Columbia’s Okanagan (spelled with 3 a’s) valley, a popular tourist area for summer water sports, fresh fruit stands and wineries. This route then heads north through the Cariboo Mountains via Yellowhead Highway 5, accessing Wells Gray Provincial Park (famous for its waterfalls).
The Central Access Route junctions with Yellowhead Highway 16 at Tete Jaune Cache, where travelers have 2 choices to reach Dawson Creek and the start of the Alaska Highway: Drive west on Yellowhead Highway 16 to Prince George, then north on Highway 97/Hart Highway to Dawson Creek, a distance of 416 miles/669 km; or drive east on Yellowhead Highway 16 through Jasper National Park to Hinton, then take the Bighorn Route/Highway 40 north to Grande Prairie, then Highways 43/2 to Dawson Creek, for a total driving distance of 400 miles/644 km.
The multi-lane Coquihalla Highway between Hope and Kamloops is an interesting alternate route. This route begins near sea level at the confluence of the Coquihalla and Fraser rivers at Hope. Then it climbs for 70 miles/112 km up the Coquihalla River and Boston Bar Creek valleys. Then, it drops down the Coldwater River drainage to the town of Merritt. From Merritt, it climbs to the Nicola Plateau before dropping into the Thompson River Valley at Kamloops.
