According to the Wikipedia, a major 18-month redevelopment of the square led by W.S. Atkins with Foster and Partners as sub-consultants was completed in 2003. The work involved closing the eastbound road along the north side and diverting traffic around the other three sides of the square, demolishing the central section of the northern retaining wall and inserting a wide set of steps to the pedestrianised terrace in front of the National Gallery. The construction includes two lifts for disabled access, public toilets and a cafe. Access between the square and the gallery had been by two crossings at the northeast and northwest corners.
