View source for Tutorial:Making Diamond Interchanges with the RHW Left Exits

Made by request(s), I will show you how to make some diamond interchanges using the new left exit/entrance ramps included with RHW 3.0.

==The Basic Stuff==

For this guide, I will construct a RHW with a 2 tile median.  You will need to have a RHW with a median of [b]at least[/b] 2 tiles in order to get use left exit/entrance ramps for diamond interchanges.

Place your starter pieces...

Drag the RHW using the RHW tool...

(Optional) Delete the starter pieces to create a RHW without any overrides.

And drag the stable network over it.

Ok, your RHW is now set up. 

==Standard RHW Diamond Interchange==

Again, I will use a road as an overpass this time.  Make sure you put two 4-way El-MIS/raised road intersections in the median tiles, and [b]make sure they are facing the right direction[/b]!

Plop 4 ground-to-elevated MIS transition pieces next to the intersections you made in the RHW's median.

...And then place the left RHW type "A" ramps next to the MIS ramps.

And you're done.  That's an odd looking diamond, eh?

==High Capacity Diamond Interchange==

This higher capacity interchange will not take up any additional room than the standard RHW left exit/entrance diamond interchange, and will look more at home in urban areas.  Like the higher capacity El-RHW diamond interchange, it will include an additional lane at the intersection and add traffic lights.

I will use an avenue for this diamond.  Place a 4-way raised avenue intersection in the median of your RHW.

Now use the ground-to-raised avenue puzzle pieces inside the median like so:

Place the left RHW type "A" ramps next to the avenues in the RHW's median.

Then all you have to do is drag the MIS coming from the ramp to the avenue to create a working connection.

And there you go.  ''Kind of a mini SPUI for those who know what I'm talking about.''

==Other Layouts==

After I made this guide, I decided to play around with my new interchange for a bit.  I ended up making this interesting creation:

This 8-ramp monster handles traffic traveling in all directions.  The new outer 4 ramps handle right turns while the original 4 left ramps handle left turns.  It is truly amazing what you can make with RHW 3.0, there's just so many possibilities!
