I know a few work colleagues who park up on Lovitt Walk just adjacent to Redheugh Bridge and will then walk over the bridge into the office to avoid paying parking charges in the City Centre.
One thing I noticed this afternoon despite Newcastle Match not kicking off till 17:30 traffic was heavy in the area at 14:30 and I thought the old estate would be a good place for a Park & Ride to alleviate traffic.
Another place I thought of was Watergate Forest Car Park in Whickham which pretty decent in size and could fit a few hundred cars in I reckon.
