A squirrel bridge is like a special walkway just for squirrels to help them cross over a busy road or highway safely. Sometimes, squirrels can get hit by cars when they try to cross the street to find food or a new place to explore. By building a squirrel bridge, people are making it easier and safer for the squirrels to get to where they need to go without getting hurt. The bridge is like a long pole or rope that's high off the ground and has little stairs or platforms for the squirrels to climb up and walk across. It's kind of like a playground for squirrels! So when the squirrels need to cross the street, they can just use the squirrel bridge instead of risking their lives by running across the busy road.
