Here are some "Sine Salad" photos taken along MO 21 south of Ironton. It joins with MO 72 and MO 49 in a 3-way triplex for 12 miles.
The first photo is taken at the east end of the triplex.

The next photo is at SR U. SINE SALAD!!!

The next photo is at SR N. MORE SINE SALAD!!!

The next photo is at the west end of the triplex. MO 49 heads north toward Cherryville, and MO 21/72 continue toward Centerville. Distance knocked out the clarity of this one :(
