The Dublin Transportation Office (DTO) has reportedly acknowledged that proposals to link up the city's two LUAS lines pose significant problems for Dublin Bus.
Transport Minister Martin Cullen has proposed linking the two lines via Dawson Street, Nassau Street, College Street and Westmoreland Street.
However, reports this morning said one third of all Dublin Bus services use some section of this route and it is considered too narrow in places to carry buses as well as trams.
Dublin Bus's terminus at Middle Abbey Street has already been moved to new locations in the Trinity College area to facilitate the LUAS line between Tallaght and Connolly Station.
Despite admitting that the proposed LUAS link-up would cause even more disruption, the DTO has reportedly expressed confidence that a solution to the problem can be found.
