雑踏警備
Preparation began in 2002 and 2003 and included minor renovation to the course, most notably the lengthening of the course for the world's best players, small renovations to the clubhouse, and also the deepening of Oakmont's storied bunkers. Other changes to the course since the last Open in 1994 included the addition of a bridge to connect to holes 2–8, which posed as a major problem causing player and pedestrian jams over the Pennsylvania Turnpike. The USGA recruited some 5,000 volunteers in order to insure the event progresses smoothly. The event was expected to, like the last Open at Oakmont, attract record breaking sell-out crowds. Crowd control was also a major problem for the USGA and its volunteers as huge crowds filled the course during the tournament creating traffic problems. The USGA began selling tickets to the general public on June 15, 2006. The USGA was expected to sell out all of their tickets for the competitive rounds by their deadline for purchase on August 15, 2006. After the sale of all tickets for the competitive rounds, any post-deadline purchases were settled by a lottery.
