It is also the main access to the coal mining community of Tumbler Ridge, as well as the W. A. C. Bennett Dam facility near Hudson's Hope.

The highway gained its '29' designation from Chetwynd north to Hudson's Hope in 1967, and then seventeen years later, the road from Chetwynd south to Tumbler Ridge was given the same number.

It follows the John Hart Highway through Chetwynd for 3 km (1.9 mi) east, then turns northwest for 65 km (40 mi) past Moberly Lake to Hudson's Hope, where a connector road to the W. A. C. Bennett Dam begins.

75 km (47 mi) northeast of Hudson's Hope, Highway 29 finally meets the Alaska Highway north of Fort St. John near Charlie Lake.

The entire route is in Peace River Regional District.
