"Broken" overpass

[Ellorienne 3]

I have built a diamond overpass for my city, but it seems to be broken. Residents cannot get from one side of the highway to the other, so I am getting a lot of no job zots.

The highway is 2 tiles wide of RHW-6S, mostly flat, running N-S, then curving NE. The overpass is perpendicular to the HWY and consists of:

--road--   --R2--  --R2 ramp B1 dual (to HWY)-- R2-- 15m Viaduct Road Start/End Piece-- --Road over RHW-6S-- --Road over RHW-6S (180 degrees to previous piece)--

and then the same in reverse to get to the other side.

What do I need to change to make it work? I made sure that all the yellow lines matched up on the overpass. Everything looks good, but just isn't working.

 

EDIT: Nevermind, I found the problem.

Could be a number of issues.

The first thing to check is the pathing, this requires Buggi's Extra Cheats.dll installed. In game press CTRL + X and a little box should appear. Right click inside and select the option "Drawpaths". This will shows the pathing used by automata in the game. You only need concern yourself with the arrows. Do they all meet up and point in the correct directions? If you post a second screenshot with the paths, that would be very helpful.

Thank you for the link, that looks very useful! (anything that enhances the very basic UI is going to help). I did however discover that it was my roundabout on the other side. It occurred to me when I recalled watching two cars just go round and round the roundabout in an amusing fashion. I've never really used one-way streets until I saw the other day how to use them to make roundabouts, so I forgot to consider which direction they were going! I had been following a tutorial on making a realistic city, and then some tutorials on overpasses, but they all were based on an outdated version of RHW so I had a lot of trouble finding the right pieces (first time with NAM and RHW).

Assuming your traffic normally drives on the right, the roundabout looks fine to me. But if your sims drive on the left (UK, Aus, Jpn etc) then indeed you need to reverse the direction, because if the roundabout isn't correct the paths won't line up with the connections.
