Protesters disrupted the official opening of a new £20m road bridge across the River Clyde in Glasgow.
Residents in Glasgow's west end oppose parking restrictions
Residents opposing the extension of parking restrictions demonstrated at the opening of the Clyde Arc.
Restrictions will be extended from 0800 BST to 1800 BST five days a week to 0800 BST to 2200 BST over seven days.
Local singer-songwriter Carol Laula, 42, said: "The restrictions are being brought in in scurrilous fashion, no-one has been consulted."
The bridge was opened by Glasgow City Council Leader Steve Purcell and Willie Haughey, chairman of Scottish Enterprise Glasgow.
As Mr Purcell spoke, one placard-waving protester got on to the stage, only to have his placard removed.
The protester, Dr John Hinton, said: "It was the sort of behaviour you would expect to see in a totalitarian state, it was almost a repeat of what happened at the Labour party conference."
Dr Hinton added: "I organise a baroque music group and we play for charity.
"We've been meeting for 15 years in St Vincent Crescent and the cost to my friends will be £1,760 a year in total - an appalling imposition by the council."
A spokeswoman for Glasgow City Council said: "The opening of the Clyde Arc, which was being enjoyed by school children and the local community, was about celebrating the history of the city and looking forward to a new and exciting vision for the future.
"We are disappointed, therefore, such an historic day has been disrupted by a small group of protestors."
