T-Bone Interchanges

Section 9: T-Bone Interchanges


A T-bone interchange is essentially a compacted directional-T interchange with sharper turns and a lower capacity, built when there is insufficient land or funds to build a directional-T. Its two flyover/flyunder ramps contract together after passing over the through highway, but then they split into two segments, resembling the bone in a T-bone steak.

You should recognize this design from the Maxis Highway 3-point interchange. These junctions are based on the T-bone design and show how compact they can be. This guide will show how to build them with a bit more realism with the RHW.

Section 9.1: Basic T-Bone Interchange (Created by Rionescu)

First lay your two highways, and don't worry about where the ending highway ends.


Lay one curved and two straight ground<->elevated transition pieces like so, paying attention to the yellow and white lines.


Then plop a FlexFly A1 piece and another transition piece like so.


Bulldoze a bit of the ending highway, and drag the MIS so they line up with the highway.


Plop two RHW-4/MIS Splitters to connect the ramps to the ending highway.


Extend the extra MIS stubs to the other highway and connect it using B-ramps.


Connect the other 3 ramps, in a similar fashion.


And your done, easy as that. This is what you should have now.


And using curves, FAMIS, C- and D-ramps, and cosmetic pieces, you can get something like this.


You could use any combination of FlexFly curves and curved transition pieces, depending on where you have space, but the one shown here is my favourite.
