On real roads
Two separate one-way carriageways meet at a Y; the street beyond it carries traffic in both directions.
The Roadform adaptation
In Roadform
A highway's two carriageways fork together into a town street with the same lanes, or the street splits into a highway.

Scale and capacity
Size changes the road widths and the space the layout needs. The guide below uses the default arrangement. The layout reserves room for wider roads.

| S | 93 × 32 m | 0 m | Highway: 1 Cross road: 1 |
| M | 93 × 32 m | 0 m | Highway: 2 Cross road: 2 |
| L | 93 × 32 m | 0 m | Highway: 3 Cross road: 3 |
