The width of the ramps is 8 cells. The width of the railway crossing is 7 cells. An ordinary road, railroad crossing, and ramps do not connect. By drawing a road 7 square meters wide, I can draw a dividing line in the center. When drawing a road with a width of 8 cells, I can not correctly apply the markings. The problem is that the width of the ramp in the cells is even. All other roads are odd.
