The Lee Valley White Water Centre, which will host Canoe Slalom events during the London 2012 Games, was completed last week.
Olympic Delivery Authority chairman John Armitt said completing the centre on budget, 18 months before the Games was a “huge milestone.”
The centre is near Waltham Cross in Hertfordshire. It has a 300m Olympic Canoe Slalom course and a 160m intermediate course.
The Lee Valley Regional Park Authority (LVRPA) will own and operate the venue which opens to the public in April.
Contractor was Morrison Construction with CLM as delivery partner. Work began in July 2009. Over 150,000m³ of material was used to form the embankments and landscaping.
