The Erskine Bridge is a fantastic piece of engineering.
We are going to build our own model bridge based on a similar design. Everyone in classes P4a and P4b will have a part to play. Each team will be responsible for building a small part of the bridge. You will need to measure carefully and use all your teamwork skills to get the job done on time.
