Translink has confirmed it is "exploring the possibility" of moving some of its 212 Derry to Belfast express bus journeys to take advantage of the new A6 road.
This comes after an SDLP MLA said the bus still takes around two hours despite the opening of the upgraded new road between Derry and Dungiven.
Foyle MLA Mark H Durkan has also called for more buses between Northern Ireland's first and second cities.

Mr Durkan, in a statement, said: "This route is a hugely popular one, enjoyed by many passengers whether for work or for leisure. However, the lack of direct Derry to Belfast Goldline express bus services has been an issue for quite some time.
“Following the long awaited opening of the A6 dualling scheme from Derry to Dungiven, the response from motorists has been hugely positive, with people lauding the smoother and indeed quicker journey to Belfast.
"That said, one complaint that continues to crop up is from people travelling via the 212 who feel they aren’t getting the benefit of the new shortened journey.
"At present the 212 route, inclusive of stops between Derry to Belfast, still takes approximately two hours."
He continued: "Translink should be making this route easier and more flexible for passengers. Public transport must be promoted and people encouraged to leave their cars at home for the bus. Particularly given its role in the fight back against climate change."
The Foyle MLA added: “I’ve liaised with Translink and sought additional express services to Belfast. Pleased that proposals are currently being considered and look forward to seeing some movement on this matter soon.”
A Translink spokesperson said: “The popular 212 Goldliner coach services operate every 20 minutes at peak times, with 32 departures from Derry~Londonderry to Belfast each day.
“We also operate additional night-time 212 Goldliner services to and from Belfast on Friday and Saturday nights.
“We keep all services under continuing review and where passenger demand dictates, we make adjustments where possible."
The spokesperson added: “We are exploring the possibility of operating some direct services along the new A6 road, assessing current service levels, demand and operational cost.”
