Little Lobo and Bernabé are bringing supplies to the big celebration in the country across the bridge -- but everyone else seems to be going, too! During the long delay, they see all kinds of people on the bridge for different reasons and speaking different languages, but when someone has a grumpy moment, they all come together to make the wait as good as can be.

People are always crossing the bridge for work, to visit family, or for play. Some going this way; others going that way. Back and forth they go. With friends on foot and in bicycles, in cars and trucks, the bridge is an incredibly busy place with many different types of vehicles. Little Lobo and his dog Bernabé have a new truck and they are using it to carry party supplies over the bridge with their pals El Toro and La Oink Oink. The line is long and everyone on the bridge is stuck. How will they pass the time? Eventually everyone comes together for an epic party on the bridge between two different countries. Richard Scarry's Cars and Trucks and Things That Go gets Mexican American makeover in this joyful story about coming together.
