Motorists who park blocking cycle lanes face a crackdown in Plymouth.
The city council is carrying out a review of routes with plans to put legal enforcement on the worst-affected.
Meanwhile all new cycle lanes will have traffic regulation orders to prevent parking.
Motorists breaking the rules will face a fine.
The city council’s cabinet member for infrastructure Mark Coker revealed the plans at a scrutiny committee meeting.
He was responding to concerns raised about the problem by Chris Mavin who said it was getting worse, especially away from the main roads.
The move has been welcomed by members of the Plymouth Cycling Campaign, which has been pointing out problem routes to the council and calling for action.
Campaign co-chair Clare Smith said blocking lanes discouraged people from cycling and was dangerous.
She said the group had been campaigning for around two years to prevent parking on the contraflow lane on Longbridge Road.
Ms Smith added that money was being spent on much-needed cycling infrastructure which was unusable.
In another example, campaign spokesperson Stuart Mee said the lanes on Elburton Road were regularly blocked in multiple places, forcing cyclists out into the carriageway.
Mr Mee said: “Not one is this very dangerous, it is a cause of aggravation to both motorists, who do not seem to understand that there is no alternative, but also results in cyclists being abused for ‘riding in the road’.
“Plymouth City Council are well aware of our concerns regarding this issue in Elburton Road as well as other locations throughout the city, and we do wonder what it will take for them to take effective action to remedy the situation.”
Cllr Mavin told the committee parking on cycle lanes deterred people from riding.
He said: “I’ve had adults saying that they won’t allow their children now to go on a cycle route, because people are now parking on the cycle routes and thereby making it dangerous.
“So if we’re going to spend a lot of money on providing cycle routes, then we need to make sure they’re kept clear and safe at all times.”
Cllr Coker said that he was aware of problems caused by parking on cycle lanes and pavements.
He said: “We’ve had a history in the city of putting in cycle lanes but not putting in enforceable traffic regulation orders.
“I have asked going forward that all new cycle routes have enforceable traffic regulation orders on them.
“So then if people do park in a cycle lane that has an order, then unfortunately they will face the consequences.
“It’s an area that I am aware of. My email box tells me how people are thinking. It’s not just cyclists.
“Where there are cycle lanes adjacent to pavements people park half-way on a cycle lane and half-way on a pavement.
“People with prams, disabled people with buggies, can’t then use the pavement."
He added: “We will do a review and it’s under way. There is one that I’ve just signed off which is a retrospective one.
“Obviously again we are talking about prioritising those schemes because they cost to do it.
“The instruction that I’ve given to the highways team is to do a piece of work on where there have been accidents, or reported blackspots, to get those looked at first, and then move on to the other schemes, as and when we have time.”
