Trumpet – 4Lane+National Road
This Trumpet Highway Entrance/Exit is set up to use a National road for the bendy part in order to simplify the part crossing over the highway. It only has one road over the top instead of having to figure out proper spacing for two one-way roads. They split off at the end to separate on- and off-ramps.
I have Built-in some basic lane math, but you will want TM:PE to set up the proper lane connectors.
Requires Network Extensions 2 for the national road and 2-lane highway assets.
