North of screenshot - continued highway but city limit is reached, nothing else is there
East - The only "city" part of my city
South - Entrance
West - future district I'm planning to build (no zoning)

Hey everyone! I'm relatively new to Cities: Skylines and I was trying to figure out a way for traffic to flow smoothly at the city entry. I've tried a basic highway interchange (which works since no zoning is established yet west and cars don't have to stop at a turn) and as you can see in the image, a partial cloverleaf. I wanted to know if there is a solution to the traffic clogging. I have watched YouTube videos but none have helped much. Thank you in advance!

Note: About 30-40% of the vehicles clogged are trucks who are trying to get to the industry part of the city (East)
