The first thing you need is a road. Place the road if it does not already exist. |
 |
The second thing you need is a highway, since the onramp is the transition from highway to road. Make sure the highway and road meet at a 90o angle, or you won't be able to place onramps! |
 |
The third thing is to place your cursor (with onramp selected from the menu under the road button) on the square adjacent to both the road and the highway. |
 |
Click once to place the onramp. |
 |
Now, if you have the space, place an onramp at each of the other tiles which are adjacent to both the road and the highway. If you placed the road right through, there will be four total. |
