Only just came across this, it certainly looks promising but like most bus stations it doesn't look bus spotter friendly as personally like standing at the crossing on Keppel Street opposite the post office.

Now to what I was going to suggest before seeing this, after a trip to shields last week and using the ferry between South and North Shields. A few thoughts entered my mind.

A.) Would it be quicker getting the Metro from South to North Shields, turns out that's a no as you'd have to travel to pelaw and change.

B.) By Bus via Tyne Tunnel, again no as no buses operate South to North Shields.

Which would leave you with current choice of using the Ferry.

So here is what I suggest but may not be possible due to the DFDS Ferry which why there isn't a more direct link between north and south shields. I suggest building a bridge to connect North to South as I noticed on the North side there is a load new road infrastructure which is closed off by gates next to the ferry terminal bus stop.

This would then create a new bus services etc, and also a Metro Bridge to connect North a South, tbh the Bridge would have to be very high and arched so that the DFDS Ferry can fit under.

Obviously this would come at a quite a substantial cost, but I think it would be well welcomed by those who live in the Shields area despite the link via the Tyne Tunnel.
