The expressway is the symbolism of getting from one point to another in some aspects of your life. The dream could represent the situations that already happened, are happening at the moment or will be happening in the future. If you are stranded in the expressway and unable to move on, it shows that you are feeling confused and do not know which way to go in your life.
