N Scale - Brick Crossing....

This is a crossing that represents using bricks in the center and sides of the crossing. You can also print brick approach roads if you want or use something else for the approach roads like what is used with the 'board crossing' here......

There will be more crossings with different materials used for the road surface in the middle.

Prints were printed with an Ender 3 Pro using Cura set on 'Super Quality' in the 'Profile' setting and with a stock .4 nozzle. I used the 'Raft' option to print all the prints. They seem to print with more detail that way.
