Richie, I am one who likes symmetry as well. Our artist daughter would say I like things to symmetrical to be artistic. I know towns and cities aren't normally built that way, unless city planners come up with a master plan for a portion of property to be developed. We have that luxury, to a certain extent.
Here are a few thoughts before I continue. I was thinking about wires for lighting. Since most of the town is setting on the two lift ups for access to the two-track yard and mainline below, I thought I should consider where the wires for lighting will go. The coffee company and freight station are on the solid base as is half of the fire house, but I will still have to make sure they don't dangle done and hook on traffic below.
The wires for the rest of the buildings will have to be attached to the lift ups and not cross under the seam between the two lift up sections. They could then be passed under the solid section near the upper track. Also, notice the street running perpendicular to the layout edge would go over one of the hinges and the tracks at the switches for the passing tracks and incline down. I like the blocked off street idea, but instead of Jersey barriers, I would use some posts in the "ground" and cross braces with a sign. That would b e more in keeping with the mid-century era.
I cut a couple of pieces of Bristol board to represent that street and sidewalks. This view is from the laundry room leaning over the washing machine. The wires are temporary wires from Menards powering the lights for the Menards hobby shop and church. I can't really move the street over so it crosses the track between the two switches because the buildings won't fit. The church really can't be moved over any more than it is.
Mark,
Have you ever considered copper tape? It has adhesive on one side. When I decided to put up a tin plate table; I was not thinking scale and I no longer crawl under tables. I laid out my small town, and then then set up the tape connections. Here is the supply.
. I was able to reach under the table and grab the wire. I stapled it to the tape and then soldered it. Here is a “T” splice. 
Again not going scale I grabbed a roll of grass. I measured the spot for each house and exposed the tape. The brown ground cover is in the middle with the tape on both sides. I soldered connections for a lamp in each building. 
Here is a portion of the town lit up.
