But First, the Missouri River

The junction's nowhere in sight because you first have to cross the Missouri River into Glasgow on Missouri 240

The junction of Missouri 5, Missouri 87, and Business Route 240 with Missouri 240 in Glasgow is at the other end of this bridge over the Missouri River. It's just a few hundred feet from the foot of the bridge in Glasgow, so the junction sign assembly is placed on the Saline County side of the river on Missouri 240.
