I'm going to rent a car at the airport but I don't want to pay for the Alibus. I was thinking of taking the tram (421) and walk the last way but jesus this is a detour. Does anyone know if you can cross this area?

Edit: Thanks for your answers! I don't have luggage, and I don't mind walking short distances (30min<) hence why I asked. I ended up getting the bus to be sure. Will be walking back when I leave the car. Way more fun than bus. Thanks again
