Limit highway access on certain highways

What's the best way to limit access to this connection that goes through my city? I want people to use both of the other highway entries in the west and the east, especially if their destination is in the area where these connecting roads end in my city, but 90% of the traffic is going through the highway in the middle. Should I use toll roads perhaps? But I'm afraid by using tolls, everybody will then only use the other roads.
