An ovoid-curve ramp is useful when an interchange ramp needs to tighten gradually within limited space. In this example, vehicles enter a larger R=90m arc, pass through a transition curve, then enter a smaller R=60m arc before joining the mainline entrance.

Extend tools continue from the end of an existing road. Transition-curve connection joins two roads more smoothly, avoiding abrupt direction or curvature changes.
