Jamestown gets a beltway bypass

Jamestown it the name of the town on my HO layout upstairs in my house.
I have been trying to get work done on the future city build, but because the upstairs is also the guest room, it's been more of put it up, then take it down/put away.
So I switched gears because I wanted to run cars.
I built a flat road coarse on the facia. It's 15 feet of orange 2 lane, and 15' (so far) of crash track.
about an 8 second run with stock cars
This build was a bit difficult because of the house itself, because it's a styrofoam geodome.
as you can see, it's a curved wall (red is about where the track is)
I built an aluminum square beam as bridge support, 1"washers on perforated stock countersink the screw heads, and some additional small pieces. Drilled and tapped most of it.
I want to get a better corner, this one is a chopped up ct intersection, but they do run thru it pretty well.
So I present the Jamestown Beltway Street Raceway
currently eyeballing installing the spiral, and sending the cars back across the floor, but, not today
we did have a minor hazmat situation with the propane tanker
You can see the constant curve I have to work around
my adjustable lift door launcher, and car basket
under the bridge
one day I will be hosting races, but for now I'm happy I can run cars
(I have a short vid, but don't know what to do to upload it)

A new installment
I explain counter sink on the washers
use carpet hold down strips,
taped for 10 - 32 countersunk head stainless screws, no drilling
some #8 self tappers attach the track holders
A Nice finish out to phase one the launch area.
the tracks were just draped over the legs of the fan before,
now all solidly mounted
enjoy the video, ask anything

p.s.
FYI, the hump sorts slow cars
a slow crappy car should not get to the corner
fast one smokes along
I had found that my videos were not clear, and I remembered 3d saying,more light
so today I went to northern tool, and bought 2 sets of tractor lights (12VDC)
1200 RAW is what is said. (x 4)

Very cool! I always wanted a geodome home. As you said, though, you have to work to make things fit.
