This is all I could suggest for now.
No way these could go around by Asda/Ikea and the Debenhams/House of Fraser end of the MetroCentre car park on the X66 or intu Eldon Square/Peterlee Bus Station for that matter, then you have the u-turn outside Billingham Asda to contend with also.
Standard sized deckers would be more suited for these services.
