Update on my Idea, The Map is now finished and is pretty straight forward by using the arrows.

The current main stands in the Haymarket would be taken out along with seating and the pavement where seating is currently would be removed and trimmed back closer to Marks and Spencer. To then create more room for road and a Centre Piece for the New Bus Station. Also the Current fencing would be moved over Two Lanes closer to the Pubs etc opposite Haymarket.

Also you'll notice coming in from Barrack Bridge side Buses/Cars etc will use the same the same stretch of road heading towards Eldon Square with Cars etc keeping as far right as possible to avoid collisions with Buses coming off Departing Stands which will be set away to left. The Box in the Centre of the Map is not an accurate representation of the size of the Bus Station, But a rough estimate of where it'll be positioned if Built.
