Slip Inn Bank was an accident black-spot on Ladgate Lane that was removed when the road was redirected, an 18th century bridge over Marton West Beck still stands on the now dead-end road.
The vanished ‘Slip Inn’ pub (demolished 1963) is shown in this Evening Gazette article.
I’ve also found a couple of references to it being unlicensed and an Irishman was kicked to death in a brawl on the bridge.
