As per above. Someone was complaining in California, it's so long that you could drive 12 hours and be in the same state. To drive east to west across Ontario on highway 17, it is approximately 1330 miles, or 23 hours by google maps.
My question to you Oppo. Is this Highway 17 the longest single jurisdiction east west highway in the world? I am thinking perhaps Kamchatka may have a similarly long highway, but I don't know for sure. Do you?
