A new Park and Ride facility will open on Friday in Claudy, one day after the new upgraded A6 between Derry and Dungiven opens to traffic.
The first cars are expected on the new dual carriageway, between Drumahoe on the outskirts of Derry city and continuing on to bypass Dungiven, on Thursday once work to remove traffic cones is completed.
It represents the completion of one of Northern Ireland's longest ever running road projects.
