A 'mass trespass' was held on Snake Pass, the picturesque road connecting Manchester to Sheffield, after officials closed the route off to walkers and cyclists.
Around 100 people turned up at the start of a 12-mile closure in the Peak District, which was implemented for motor traffic on February 21 after heavy rainfall caused by numerous storms led landslips.
However, earlier this week, the council said the road would be shut off from cyclists and walkers as well, DerbyshireLive reports.
That decision was met with anger, and talks of a "mass trespass" started circulating on social media.
Around 100 bikers breached the A57 Snake Pass barrier in Glossop as part of the event yesterday (March 12), and the group were met with no resistance.
Instead they were handed flyers from the council warning them to be careful.
Speaking to one of the cyclists taking part in the event, he expressed the idea of challenging the emergence of "car culture".
Twitter user Dan told Yorkshire Live that "car culture" is the tendency of blocking roads for everybody else merely because cars cannot pass by.
Dan said: "I think it's important to challenge decisions led by 'car culture'. Just because a short section of the A57 is not passable by cars (due to road works) @Derbyshirecc decided to close the whole road. It doesn't make sense."
He added that it was cheeky for the council to close roads for cyclists' safety, when cyclists are often put in grave danger by motorists who drive dangerously on the same stretch of road.
Dan said, "When the A57 is open, we all know how dangerous it is due to the minority of motorists who treat it like a race track. Yet, the main reason @Derbyshirecc gave for closing to cyclists was 'safety'."
The closure has been initially said to last a month while the site is investigated, with the closure listed as lasting until March 22
A suggested diversion for the route measures 27.5 miles and takes an hour.
