New traffic lights system to be installed at busy junction on Derry's Buncrana Road Renewed concerns over continuing delay to major upgrade of the road The new traffic lights will be erected at the junction of Buncrana Road and Springtown Road. Reporter: '); '); The major upgrade of one of Derry's busiest roads appears as far off as ever after the Department for Infrastructure (Dfi) again failed to provide a start date for the £70 million project. The upgrade of the Buncrana Road was first mooted some 40 years ago. Hopes that work would commence in the near future rose this week after it emerged that traffic lights are to be erected at the Springtown Road junction of Buncrana Road.
