best way to make a bridge...?

[michaeldcannaday 42]

I'm trying to build a bridge to connect onto the NAM roadway ( in picture below ) but I can't seem to make it happen with Maxis nor RHW. It's always giving me 4 lane bridge highways when I attempt to built a bridge, and dosen't give me an option to lay a 6 lane roadway just like the road that's already built to match. What's the best solution??

Convert to a 2-tile network and use a 2-tile wide bridge; there's no 3-tile wide bridges, since those are impossible to make using conventional means.

Well there aren't any bridges for AVE-6, and there aren't even overpasses for this network. To make a bridge in this case, you'll have to convert to RHW-6. However, Ave-6 is a three-tile network like the RHW-6C, but it's not possible to make 3-tile bridges because the game's EXE requires a one-tile gap between parallel bridges.

But you aren't completely out of luck though. You can do an elevated RHW-6C across this river, but it's a pretty advanced method that involves lowering the sea level outside of the game. (the "set sea level" cheat works too, but it has other negative side effects) What you do is edit the values of your terrain mod in a program called iLive's Reader. You would want to change the sea level value using the Reader and then open up SC4 and load your city and build the overpass.

 

This is something that I haven't done myself (haven't had a need for it yet), but MandelSoft demonstrates how to do this in one of his videos of him playing SimCity 4. View it on YouTube here: https://www.youtube.com/watch?v=qNM5cDXCeYc

Your way works too, but it would require him to completely tear up the surrounding area to put in S-curves on either side to go from RHW-6C (which connects directly to the TLA-7/AVE-6 since both are 3-tile networks) to RHW-6S in order to build an RHW-6S bridge.

 

If you'd hate to have to destroy some surrounding buildings in order to accomodate the RHW-6S to 6C s-curves, then you could take a stab at my suggestion, which is far more advanced, but doesn't seem very challenging as long as you know what you're doing with the Reader.

Except the method I had in mind didn't even need an RHW bridge, but instead a transition from AVE-6 to Avenue; takes no additional space, except you do lose two lanes. The loss of lanes shouldn't matter much if you consider the "room for improvement/expansion" or "this is a temporary/cheap fix" factor. If you don't want the capacity loss, convert to RHW-6C and put an RHW-6C to RHW-4 transition, and then use an RHW-4 bridge.

There are far more easier alternatives that exist. There's no need to restrict yourself to one single option, especially if one requires advanced terraforming.

Oh, that's a simpler idea than what I was thinking! Having looked at the documentation for the RHW and NWM, I find that the RHW-4 has more capacity than the AVE-6/TLA-7, probably because of the higher speed on the RHW. With that in mind, I should convert one of my Avenue steel through-arch bridges to an RHW-4 bridge of the same type, since on both sides of the bridge I have an AVE-6.
