The announcement of a new bus route suggests the final go-ahead for a new primary care centre is imminent.
NHS Norfolk and Waveney has already been given planning permission for the new centre on Nar Ouse Way in King's Lynn.
It is waiting for its business case to be approved by NHS England before work begins.
But while a decision is expected to be announced within days, bus firm Go To Town has announced a new route through Lynn which will serve the new care centre and a new GP surgery being built in the Woottons.
The Norfolk and Waveney Integrated care System said: "Now that planning permission has been received, the next and final step is for NHS approval of the full business case.
"A decision on this is anticipated in August and, if approved, the building work will start in September. The building would be planned to open in May 2024.
"The centre at Nar Ouse Way will house a range of services, including community care and outpatient services from the nearby Queen Elizabeth Hospital.
"It will be known as King’s Lynn Health Hub, and will be a modern, fully accessible, and digitally enabled facility that will help to transform how health and care services are delivered in the King’s Lynn area and increase access to services for people in the town and surrounding areas."
Elsewhere health services in King's Lynn and West Norfolk are undergoing major change with the announcement the crumbling Queen Elizabeth Hospital will be replaced by 2030.
Work is already under way on a new diagnostic unit which will increase capacity and help cut waiting lists at the QEH.
The hub is part of a £25m package of four schemes across Norfolk and Waveney.
