I wonder whether more of a uniformed entrance into Newcastle would be of benefit to buses, because really all GNE Buses should be close together for the best service.

Services from the Metrocentre could use the Swing Bridge, then up Dean Street along Worsick Street, up John Dobson Street, Around to Eldon Square and out the current way

Services from Gateshead - Swing Bridge, up Dean Street right at Worsick Street then either Market Street or John Dobson Street into Eldon Square.

But also I would personally knock down the Car Park at Eldon Square and build another few stands maybe like 6 for other GNE services so they can all be in one location.
