Highways tunnel under water - Cars not being able to go under the water

Well, the thing is, as RHW doest not allow to make tunnels, I did what pretty much everyone else does, I tricked the original game features to allow me to make tunnels, this worked so far with trains, I made tunnels that go under water and even as far from one point of the city to another, now... The original highways have worked on flat terrain and even more, but there is something I'm making wrong and I can't seem to understand what...

As you can see, the highway allows me to make the tunnel that pretty much goes along most of the city until the other side of the channel.

The train one works just fine.

Now, the other entrance /out is being shown:

However, when I try to drive the cars in or into out of it they can't go on once they reach the shores, something stops them from going on. I even made several other atttemps with the terrain below the water but the trains don't seem to be affect by it. 

Does the terrain has anything to do? Did I make it too deep? (As I said before, trains don't seem to be an issue)

Thanks in advance! :)

Did you build the tunnel by levelling the terrain that's underwater, drawing the tunnel and then sinking the terrain again? That's how I know it works. If is that, you can check with the drawpaths cheat if the tunnel is correctly connected.

If the tunnel being used is a subway conversion or other TE lot, then you will not get working UDI/Automata going through it.

The best solution is to use the MHO at ground level, which does support tunnels which work with RHW-4, those should be fully functional. Of course this requires having the MHO mod from the NAM installed.

    Yes, I did, could you please remind me which cheat should I use to check that? Thanks!

    Perhaps I didn't get it right, I used the original Maxis ground highways, not any of the NAM. I've already tried and they worked.

    And yes, the correct way to do this is with the Maxis ground highway. If you use the MHO, it will also match perfectly with a RHW-4, so that's an extra advantage.

    Just adding to what @matias93 said above...

    Then there's the oppositely named HidePaths which rather does what it says once you're done. *;)

    Interestingly I found saving a city tile with paths enabled will render them on the region snapshot preview. However they're toggled off and not stored as a preference, meaning re-entering the city will have them disabled as per the default.

  • Yes, I didn't know how to hide them, but still, I fixed it... or sort of. If it's too deep, cars and trunks can't go either down or up, so I made it smoother. I also did a space when the highway resurfaces before doing yet another tunnel, it seems it was too much for the game to understand the tunnel goes through half city plus the channel.

    If the depth or steepness of the tunnel is a problem, usually you simply won't be able to make the tunnel in the first place. I.e. when dragging it will go red and give an error. So if the tunnel was being built, that isn't really the reason why sims may not choose to use it.

    Which suggests to me perhaps the tunnel/segment was so long that sims simply found what they considered to be a quicker route from A-B that didn't involve using the tunnel. In which case you won't see any actual usage of it.

    Drawpaths doesn't tend to work terribly well with tunnels, because they are not visible, so whilst the pathing is technically there, aside from the portals, you simply can not see them. For some subterrainian networks, switching to Subway view may help, but I'm pretty sure in the case of in-game tunnels that won't help.

  • I think perhaps I haven't made myself clear on the reality of my... conundrum here. I don't mind the sims using it or not, actually once you start plopping buildings the actual sims and the whole transportation sytem becomes irrelevant. Nobody uses it anymore for plopping the building makes that traffic disappear, the population is there but every single trip pretty much stops,  unless I chose to keep any of the buildings the game plops by itself. Nowadays I'm mostly into making it a coherent style than going along with what is being built by the game.

    My trouble was functionality, I could just could have left it there, It looked the part but I wanted to work with the Udrive and it didn't. Now, it sort of does, I'm not a 100% happy with it but it works. :)

        Hey Folks
         
        OK as you can see from the pic I get a red line at the entrance to the tunnel. It looks like it doesn't go through. Not sure if it is or not turned on drawpaths and see nothing for the tunnel.
        What you see in the pic is RHW 4 tunnels. I attempted to run RHW through the hill but all I get is red line. I attempted to just run RHW through by dragging it but all I get is the red line. These tunnels I have I got here on the STEX and comes with just about all the networks tunnel entrances.
        I have the green arrows shown by the drawpath cheat but you can see there is that thin red line going across the entrance.
        Any thoughts?

        Hey folks
        I'm trying to build a HSR in my region. My only hang-up now is I can't find a HSR over RHW-6 puzzle piece. When dragging HSR across the RHW it trashs the RHW.
        I thought there was a puzzle piece for this but can't locate it! I have NAM 36 installed (RightHand).
        Is there a puzzle piece for this or a puzzle piece for RHW over HSR? If so where can I find them?
        TIA

        Hello,
        First of all let me say I'm new to this forum and to SimCity 4. I installed NAM to my computer with SimCity 4. Now while I was making the highways for the city that I'm working on, I noticed that I couldn't connect an exit from the RHW to lets say an avenue or a regular road or even a street.
        So basically I'm stuck at this stage. Any help on where I can find something to connect this to a road would be appreciated. Or is there any way to make an exit with the NAM (with the default ground or elevated highway, there was the option of ramps and that could've been easily connected to the roads. With RHW, I don't seem to find any option like that.)

        Thanks

        Good day all, I just installed NAM 36, and I get several questions of NAM 36:
        1. Is there any transition pieces to connect between RHW and Avenue? It looks like the median line doesn't match like screenshot below:
         
        2. When I connect MIS to Avenue, why there is no traffic light from the MIS direction?
         
        3. Why the traffic light on my elevated road junction always steady green?
         
        Anyone know what's the problem?
