Helper Cars Season 1 Episode 83 Tunnel

Today, cars found themselves stuck in front of a bridge that had been raised to allow a ship to pass underneath on the river. Until the bridge goes down, no cars can cross! The assistants' cars were caught in a traffic jam in front of the bridge. The cars came up with the idea of ????building a tunnel under the river so they wouldn't have to wait for the bridge to go down, as sometimes an ambulance or a delivery car has no time to wait for the bridge to close!
