I have to laugh at all the poeple saying to not use the coq, it doesnt run all the way accross bc, it is only 200km (aprox) and is the most efficent rought from the mainland to the interior. yes it is two lane, 3 lane in spots) but it is the highest highway throught bc and has some nice views and goes through some senic areas. I have taken all three routs and basicly if you are going to merritt or kamloops or north you take the coq, if you going south you take the 3. if your going east you have three roughts but you take the coq to get to the starting point for two of them. Kamloops is the hub of BC (travel wise) and the coq ends here, so basicly from hope to kamloops is the coq, with a newer side shoot to kelowna. ya you can take the fraser canyon, very boaring in my opinion, can only look at desert river vally for so long on a single lane hiway that take quite a while longer.
