NAM Real Highway Cloverleaf Tutorial

[SimCityJack 10]

I have been trying to work with NAM RealHighway Intersections but, I found them to be very time consuming and most of the times I gave up. Finally, I decided to create a simple Cloverleaf Interchange which I think, turned out to be not bad at all and quite easy to construct. So, let's get down to it.

We will be constructing the interchange below 50 X 50 tiles:  

Step 1.

Build a straight RealHighway (RH) of about 60-70 tiles long. I used the 8-lane RH8-S. Then build 1-Level RealHighwayFLEX Height Transitions (as close to the Highway as possible), where you want to intersect the highways.

 

2. Then start a new highway before the ramps ( I used RH6-S) and drag Highway to join the overpass.

3. Place a FLEXRamp Type A1on the ground highway, 1 tile away from the bridge, as shown on the image below. The ramp on the other side of the highway is placed 1 tile further down. I noticed that after I finished the tutorial so, don't pay attention to that.

4. Place a FLEX Ramp Type B1 on the overpassing highway, just after the height transition, on ground level:

5. Using the Road or Traintrack tool, mark a 10 X 12 tile rectange to use as a guide:

6. Find the RealHighwayFLEXFly and place two MIS L0 90-Deg (Type A2) pieces, as shown on the 2nd picture below:

7. Press TAB once and place an MIS L0 45 Degree (Type B2) piece, as shown below:

8. Using the Network Eraser tool, erase the extra piece (if you don't erase that, the ramp will break when you join join the gaps):

9. Drag highway to connect the pieces:

10. Place an Exit ramp (FLEXRamp Type B1), on the ground highway (11 tiles away from the rectangle you marked before), as shown below:

11. Place an Entry ramp (FLEXRamp Type B1), on overpassing highway, 10 tiles away from the rectangle you have marked before:

12. If the Exit and Entry ramps have been placed correctly, you should be able to join them by dragging a diagonal Highway:

13. Repeat the process for the remain 3 sides. You can use the position of the existing ramps to place the opposite ones, without having to count tiles agian.

You can see that one of the ramps on my Cloverleaf is placed 1 tile further. I have fixed that, but, I only noticed that after finishing the tutorial images so, forgive me about that :-)

14. When you finish, you may decorate your Cloverleaf to look  more relalistic:

FINISHED!!!

This is a beautiful interchange but can be reduced in size. If I remember correctly in SC4Evermore's discord server they circulate NAM Semi-official images in creating the most compact cloverleaf interchange possible. Perhaps @Lucario Boricua can upload the image here

I'm sure there are different ways to create this interchange and make it smaller. I've seen quite a few. This is just a simple and fast way to create a Cloverleaf, with the cost of a larger area.

Thanks for the comment, mate.

In response to @Ulisse Wolf's mention, here's my RHW compact cloverleaf interchange tutorial. This version here is made for RHW-4 / 6S with a wide median, but it's possible to adjust the median spacing and starters to match other RHW configurations. note that this one uses a combination of FLEX pieces and simple drag patterns, no puzzle pieces whatsoever.

 

To start, make sure to start constructing it from the inside, but do be careful with the placement of the L0-L1 FLEX height transitions. At this time (NAM 47 for players and NAM 48 in development), those pieces must be placed from the L1 side. It also helps to build each quadrant separately, as there's symmetry involved.

Alternatively, use the drag pattern (draw 2-cell stub, overclick the end with elevated rail, draw another 2-cell stub ending right against it, then override with the L1 and L0 versions of the same network).

 

Once all the pieces are in place, use the RHW tool to connect them. If everything overrides correctly, it should look like this:

 

Enjoy the result and place it in a city of your liking! Excluding the outer lane drops, the interchange occupies a 25 X 25 cell square. Still sizable, but realistically scaled.

Thanks mate. That’s definitely better
