The stadium has two covered stands along the touchlines of the pitch. The encroaching spectators were slowly edged back behind the touchlines. These are often seen on the touchlines of sports fields on Steadicam systems. A rugby union "pitch" has "touchlines" and "dead-ball lines", respectively. The two touchlines must be between long, and be the same length. To signify this, the horizontal line of the penalty area was extended to the touchlines. In that stadium, the retractable-roof also opens lengthwise from the center to the touchlines.
