Further demonstrations are planned monthly on Sundays in Dublin city centre, demanding a physically separated Liffey Cycle Route.
Around 300 cyclists have taken part in a protest, calling for a safer route along the quays.
Hundreds of people took to the streets of Dublin city centre this morning to demand a safe cycle route along the Liffey Quays. We'll be back again on Sunday 12th August for the next #LiffeyCycle! @ireland pic.twitter.com/CCW22CiDUl— Dublin Cycling Campaign (@dublincycling) July 8, 2018
The Liffey Cycle Route was first proposed in 2011, but nothing has happened with it yet.
Dublin Cycling Campaign spokesperson Ciaran Ryan said that they want cyclists to be separated from traffic.
"What we'd be expecting in general terms is a physically separated cycle route along the Liffey Quays,
"So we're talking about using kerbs or bollards to create a proper, safe cycle route, so people aren't mixing with motor vehicles, with buses, with trucks, with cars, with taxis, the kind of heavy vehicles that are travelling up and down the quays every day."
