When Northern Approach Road was built land was set aside with a view to providing segregated bus lanes in the future. It's not clear what current plans are, if any exist.
Provision for cyclists should also be made on what is an important route between the Town Centre and North Station, and the Hospital, Mile End, the A12 J28 Park and Ride, and Severalls Business Park. e.g. Cambridge's Guided Busway also has a shared use path alongside.
