Junction of Highway 200 and Highway 37 Northbound drivers have a difficult time with this junction. Here is the most detailed description I can offer. Immediately after the sign at 159.3 km. is a tope. Immediately after the tope, a small street joins on an angle from the west. Immediately after the small street joins, Highway 200 starts to curve to the east. At this point, look for a small traffic island with a few trees in the middle of the road. This is the junction. As Highway 200 curves to the west, it becomes Highway 37. Stay to the right of the red truck in the photo. Hwy 200 northbound traffic goes to the right of the blue van and to the left of the treed area in the photo. If you miss the left turn, you'll have to go about 0.5 to 1.0 km. to find a place to turn around. Southbound drivers should be aware that Highway 200 between La Mira and Petacalco has many topes. Topes are common in settled areas, but are more common on this portion of Highway 200. La Mira to Petatlan From the junction of Highway 37&200 at La Mira in Michoacan to Petatlan in Guerreo.
