I believe there's plans to ban cars along it outright so it will be only buses and cycles running along it.
I edited the post after to include the latest plans, they planning to build a new road that loops around avoiding the bridge - https://www.iamp-public-consultation.co....8850e2.pdf
It was 100% done for buses though, was done under this grant - https://northeastca.gov.uk/wp-content/up...ackage.pdf. Details are on Page 9.
The cities mentioned are Newcastle, Sunderland and Middlesbrough though, X9/X10 possibly aswell.
