The new State Laboratory is in the Backweston Laboratory Campus, which is on Stacumny Lane, off the road from Lucan to Celbridge. Coming out the N4 from Dublin, pass the Spa Hotel and take the next slip road to the left (past Kew Park). Turn left at the T-junction towards Celbridge. After approx 2.5Km turn left at traffic lights into Stacumny Lane, the campus entrance is 500m along on the left and the State Laboratory is the building 200m in on the right.
