According to media reports, thousands of people have turned up in Cambridge to watch the funeral of Stephen Hawking.
The University of Cambridge is working with the police to oversee the area around the Great Marian Church, where the service will be held at 2:00 pm on Sunday (March 31st)
There will be no public access to the church the funeral is intended as a private service for family, friends and guests.
But the authorities have forbidden parking at the King's Parade and Senate House Hill from 6 to 18 pm on Sundays.
It is not known how large the masses will be, but given the worldwide fame of Prof Hawking, some sources predict big numbers.
The University said in a statement, "The funeral service will be attended by Professor Hawking's family, invited friends and colleagues."
"This is a private service and nobody without an invitation will be the entrance to the Church before or during the funeral service
"Police, city councils and event control officers will be available to assist the public in the affected areas."
There will be some road delays while the traffic is briefly stopped to allow the funeral procession to pass on its way to the church.
However, a university spokesman said that despite the fact that it was a "busy holiday weekend" it would be "business as usual" in the city center.
He said, "The vast majority of the city center is open as usual, there will be no ongoing road closures, but more traffic jams will occur as the funeral procession passes through the city."
"Some Pedestrian accesses will also take place around King's Parade and Great St Mary's.
"Members of the public should expect some traffic jam Anyone who wants to visit the Great St Mary's area, including the King's Parade, should consider this when planning their day."
