Straight Ahead to Altamont and Trenton

US 69 at Missouri 6 west of Altamont

Just west of Altamont, Missouri 6 and US 69 intersection. When going northbound on Interstate 35, traffic is advised to take the US 69 exit to go to Trenton, even though US 69 doesn't go to Trenton. Here's the solution: four miles to the northeast, traffic going straight on to Trenton stays on the road, which becomes Missouri 6.
