The project is made up of two phases:

• Phase 1 looks at road safety, walking, cycling and bus priority along the A1307 between Haverhill and Cambridge.
• Phase 2 is a new busway between a new A11 travel hub and Cambridge Biomedical Campus. It will link the new Cambridge South station to Granta Park and Babraham Research Campus. A path for walkers, cyclists and horse riders will run alongside the busway.
