The project includes a 214-space car park, new access to the Belfast and Dublin roads at the King Street roundabout, a development platform establishing a new investment opportunity, and a new link extending the Waterside Greenway and further enhancing walking and cycle routes for the city.

The First Minister Peter Robinson said: “It was a great pleasure for me to attend the official opening of Ebrington Square in 2012 to see at first hand the huge transformation taking place.

“Today’s completion of this £5.5m project is evidence of the Northern Ireland Executive’s commitment to invest and create employment opportunities in the North West to make life better for everyone.

“Ebrington Square has now become an integral part of Londonderry with the potential to provide high quality office accommodation along with providing a tremendous platform for major events and performances.

“Only last year I was delighted to have the opportunity to visit the Turner Prize exhibition at Ebrington, the first time that it has been held outside England. The ability to attract major events such as this is proof of Northern Ireland’s ability to deliver on a global stage.”
