The word "Derry" could soon be added alongside "Londonderry" to road signs across Northern Ireland under Stormont plans.
A "dual-naming" policy for road signage is being worked on by the Department for Infrastructure.
The move was confirmed to SDLP MLA Mark H Durkan after he asked the Infrastructure Minister if he would consider including "Derry" alongside "Londonderry" on signage for the new A6 road.
In response John O'Dowd said: "I can advise that my officials have been asked to review the current approach with a view to moving to one that accommodates dual naming on traffic signs across the network."
The department refused to elaborate further on what a "dual-naming" approach would entail.
Mr Durkan welcomed the dual-naming plan as an "inclusive" way of "accommodating both traditions".
The Foyle MLA said: "I see no reason why anyone would object to inclusive signage which recognises the name that the majority of people in Derry use to refer to our city while accommodating both traditions.
“Alongside being more inclusive, I believe this move would help put an end to the constant defacing of the existing signs which has been going on for decades.
"It would also end confusion for the many tourists visiting the city who are left wondering if they are heading to the right place."
But DUP MP Gregory Campbell called on the Infrastructure Minister to focus on completing the A6 rather than "pet projects".
He accused Sinn Féin and the SDLP of "putting politics above the need to improve conditions faced by motorists".
Mr Campbell said: "This is a clear demonstration that the Infrastructure Minister appears more interested in road signs than the roads themselves. The A6 should have been opened months ago yet it still isn't finished."
Rejecting Mr Durkan's argument about vandalism, the MP added: "The responsible approach for any minister and department is not to encourage vandals by being seen to reward their criminal damage.
"John O’Dowd should focus on his job of getting this road opened."
The plan is the latest political disagreement over signage along streets in Northern Ireland.
