The new steel-framed grandstand features a cantilevering roof which juts out by up to 45m at the western end.
The completed structure will incorporate five star corporate facilities, restaurants, bars and viewing facilities for the public.
A new arrivals and reception area will incorporate a visitor attraction, including a museum to celebrate the history of racing in Ireland and the contribution Ireland has made to the sport worldwide.
A new parade ring will ensure that more patrons can share in the excitement and build-up to the racing. A new weigh room will provide even better facilities for the jockeys.
Demolition of the old Curragh grandstand and Weigh Room commenced last January and was completed in June. This was carried out while work was also ongoing on the reconstruction of the historic Viewing Stand, which was first built in the 1850s to commemorate the visit of Queen Victoria.
Work on the refurbishment is due to complete in time for the 2019 racing season.
