Closures first came into operation on a trial basis 15 months ago, with several streets shut at full time to allow supporters to exit the stadium and surrounding areas safely.
The council has kept the closures under review and after consultation with Newcastle United, the club’s Fans Forum and Northumbria Police, a multi-agency safety advisory group has decided to extend the closure period to the start of the game as fans make their way into the stadium.
The new arrangements will be operational from this Sunday and on all other matchdays.
Cabinet Member for the Environment, Cllr Nick Kemp, said: "The safety of football fans on match day has, and always be our paramount priority.
"We introduced these measures on a trial period over a year ago, so we could monitor the effects and listen to fans.
"It is clear that many fans wanted the closure before the game as well as after the game, so we’ve decided to bring in this change.
"These measures were introduced shortly after the Westminster Bridge atrocity and purely for precautionary measures as happened at many other grounds across the country.
"I would like to stress that there is nothing to suggest that the ground is any more of a target and we are merely listening to fans’ wishes."
Car parks will remain open as normal on matchdays, but motorists may have to change their access route to some of them near to the ground.
