Answer: The correct answer is "interchanges." The interchanges on a roadway will help drivers to enter and leave a roadway without very many interruptions. The traffic will be able to enter and exit an exchange to make a smooth transition to the roadway they are going too. Traffic on the roadways will be able to see when a car is entering and exiting the roadways and have ample time to move to another lane.
