Not sure what you mean about "not have full on/off ramp pairs"? The highway sign for the Penn exit states 1/4 mile (right at the Agnew exit). Not sure how there are measuring the distances? But they can be misleading as I noticed more than once the distance to/from Tulsa/OKC is 90 miles in one direction and 120 in the other. LOL Even if it is 1/2 mile, there is the Boulevard exit already halfway constructed in between Agnew & Penn (if evenly split, that brings us back down to 1/4 mile spacing). If the 1/4 mile sign is correct the spacing between the 3 ramps is less than that (1/8th?)
Understand what you are saying about higher traffic count closer to DT (but isn't that situation exacerbated by having 2/3 fewer exits?) As far as land allocation, they could get all the land they needed to do it properly. Right?
