Ok finally time to get on my way (hit the open road) and make progress.
I did a fit check in the originally intended position for the one lane bridge and determined a few things:
1) the bad news is, it's a smidge too wide. The good news is, i have enough excess width that I can narrow it slightly and that'll be fine.
2) the bad news is, as feared, the slope is a little much, it looks a little goofy sloped down. The good news, it's not too sloped where I'll have to add extra height, all I'll need to do is angle the slot (that accepts the side edge of the ramp) and that'll make it level again -- level with respect to the glass / expression lighting, but this looks correct to the eye. So, next iteration will have updated width and angle slot. I may attempt to add the screw attach lobe on this next run too.
too sloped
proper angle, will adjust accordingly
I also took a look at if this could mount at the S-curve in the ramp. Obviously it's too much going on if you have my Signals mod -- but if you don't, this might be an option. I really like being able to see the side of the bridge, but it also slightly crowds the time machine. Anyway, thought I'd post this rough fit pick to see if anyone wants this as an option.
picture it without the dog/hydrant?
I looked more at the lighting-leaking-out-the-wheelwells -- I found a good color matching paint, and it looks like this might work, just painting over the lights/glue.

Finally, I fit checked the road scene in the back left corner -- needs some minor reshaping/resizing. I pulled the plastic from up there and scanned it to use as a pattern for the attach lobes and positioning, so I'll have an updated version (with more road instead of inner shoulder) soon.
