In Dublin, a major row has erupted between a local council, the National Transport Authority and local residents.
More than €1.1 million has been spent rebuilding a busy roundabout, which residents say has caused traffic chaos.
They say the changes have added significantly to their daily commutes and that the junction is now congested at all times of the day, not just in the mornings and evenings as once was the case.
The local authority say the plan is part of creating a safer cycle route connecting Tallaght to Ballyboden.
They insist the congestion problems will be resolved but some residents in Knocklyon and the Scholarstown Road area want the roundabout restored to how it was before.
