Thanks! art128, I agree about adding room to merge in the future. We may eventually have support for that particular inside flex ramp at that level soon. For now, those Sims will have to get out of each other's way.Expanded on the last interchange a bit. This interchange is actually inspired by an interchange at 75 and 696 in Detroit, although the actual interchange has a four-level crossing as opposed to my more Tex-ified three-level crossings:Throwing in some Texas Turnarounds for good measure:To the west of this interchange, there's a three-way interchange with some additional frontage support:And down the way, a DDI with Texas Turnarounds. Somewhat unnecessary given the traffic flow of a DDI. Regardless, it provides some congestion relief.Actually, TX-DOT is planning to build more DDIs and SPUIs in the future. Of course, we can't do anything without frontage roads, so they actually look a lot like the last pic.Some fun examples if you're interested:Here are some plans for what we call a "Modified SPUI" with frontage roads and Texas Turnarounds:And of course, here's our take on the frontage DDI:Fun stuff!-Blade
