Section 10: Windmill Interchanges


A windmill interchange is similar to a turbine interchange, but it has much sharper turns, reducing its size and capacity.

A variation of the windmill, called the diverging windmill, increases capacity by altering the direction of traffic flow of the interchanging highways, making the connecting ramps much more direct. The interchange is named for its similar overhead appearance to the blades of a windmill.

Section 10.1: Standard Windmill Interchange (Created by McDuell)

In this guide I'm going to show you how to create a basic windmill type interchange.


First, put down 2 elevated Ramps and two starter pieces. Bulldoze the outer end of the starters.


Build two RHW->ERHW transitions as close to the existing ramps as possible.


Count 7 tiles of free space off the center and build 4 FlexFly A1 pieces. Leave the four builder tiles as reference points to make tile counting easier.


Now build the two ERHW->RHW transitions.


Create two draggable A-ramps on the ground RHW.


Complete each of the left turns with a curved MIS->EMIS transition, a MIS 45 wide right turn, and a RHW/MIS-splitter piece.


Finish the ERHW center part, then put down four MIS 90 right turns. Connect the two EMIS sections and build the missing two EMIS->MIS transitions.


Connect all MIS parts. If you can't get the short diagonal parts to properly connect, just start from the other end and drag the MIS in the opposite direction. Build draggable A-ramps to connect the right turns to the main RHW.


Build FARHW outer curves, RHW4/FARHW-splitters and RHW4->6S transitions on each branch. Bulldoze any helper piece leftovers.
