Southbound MO 13 pictures
The below picture is maybe a mile before the interchange; the advanced speed limit reduction signs marking the end of the MO 13 expressway are in the distance.

The pedestrian walkway runs through the center of the interchange:

The rebuild of the US 60/US 65 interchange is proceeding. Many of the piers for the flyovers are up (the uncooperative weather as indicated in the DDI pictures prevented taking photos of the construction.
Most major arterial-arterial intersections in Springfield are now photo enforced.
Good to hear about the 60/65 construction. I remember one of the only times I used that interchange while I was in Springfield, I happened to arrive around the same time as a train. Boy, that was a mess.
Shame to hear about the photo enforcement. When I lived there, only the Sunshine/Campbell and Campbell/Battlefield intersections were photo enforced.
So looking at the pictures on here and these pictures on Wikipedia...I'm guessing this operates like a dual-SPUI? Maybe a 'dual-point urban interchange'? I guess it would be easier to understand seeing it in person.
