No Side by Side Bridges?

[GrandpaKim 7]

I have checked the manuals and the forums with no luck.  This kinda surprised me since someone must have run into this problem before.

I am running an RHW 8S across a river.  Of course I can't do that, I must split it, so it is now set up with 2 MIS and 2 RHW 6S.  I can run any one of those bridges across without a problem but if I try a bridge immediately beside it, it won't go, just won't play the game.  I can run two bridges across if they are not adjacent.  For instance, i can run the southbound 6S and the northbound MIS or vice-versa.  No way can I build all 4, not even 3.  I saw it mentioned that one-way roads must be run in the correct direction, so I tried that.  No soap.

Is this normal?  Something "everybody" knows (except me)?  Or do I have an unusual glitch?

There has to be a one-tile gap between bridges. This is hard-coded into the game and there is no way to change this. In order to do two-tile RHW bridges, (RHW-8S or -10S) you need to use the Maxis Highway tool, and drag that across the river in the direction that traffic will flow. Then you will be able to build an RHW-8S (or -10S) bridge. This also allows you to build an RHW-4 or -6S bridge with both directions on the same span (this means you won't need a one-tile median leading up to these bridges).

Thanks Compdude.  I didn't know about the 1 tile gap.

You're welcome!
