Highway 97C begins near Peachland, at a trumpet interchange on Highway 97 known as Drought Hill. The section of Highway 97C east of Merritt is 4 to 6 lanes expressway with a speed limit of 100 km/h and the section east of Aspen Grove is freeway with a speed limit of 110 km/h. The road was formerly 120 km/h. Expressway and freeway sections have very few exits along its route. Its highest altitude is the Pennask Summit, above sea level. Highway 97C travels on this freeway 82 km northwest to Aspen Grove, where it converges with Highway 5A. This stretch is a four-lane rural arterial highway. Highways 97C and 5A share the long route between Aspen Grove and the Coquihalla Highway at Meritt, where Highway 5A continues northeast and Highway 8 begins. Highways 97C and 8 travel along Nicola Avenue through Merritt and share a concurrency to Lower Nicola, where Highway 8 continues west to Spences Bridge and Highway 97C diverges north. Highway 97C goes north for 42 km to Logan Lake, then northwest for 57 km to Ashcroft on the Canadian National Railway. Highway 97C then travels 6 km west from Ashcroft to where it converges with Highway 1, which takes Highway 97C north for its final 5 km to its end at Highway 97 in Cache Creek.
History
Highway 97C is a relatively new route, commissioned on October 1, 1990, which is in total length, and was constructed as the third phase of the Coquihalla Highway Project. Construction was completed in 1990, with the cost totalling to $225 million in 1987 dollars. Highway 97C was originally intended to have a freeway connection with the Coquihalla Highway approximately south of Merritt, near exit 256; however due to protest by local residents in Merritt on the grounds that it would take tourists away from the area, the project was postponed and the freeway remains incomplete to this day. In July 2007, the shared roadway of Highway 5A and 97C was upgraded to a 2-lane road in each direction, the last segment required to enable 2 lanes in each direction when traveling between Vancouver and Kelowna. When it was constructed, initial proposals had it designated as Highway 8; however, communities on the route preferred it designated as an auxiliary route of Highway 97, hence its Highway 97C designation.
