Security guards are authorized to perform detailed vehicle searches and deny vehicle access across the dam. Drivers may not stop their vehicles to take pictures or sight see during escorted crossings. Pedestrian traffic across the dam is not allowed because of safety considerations.
Operations officials note there could still be closures. The district may, at any time, close access to traffic for extended periods of time due to operations, maintenance or construction-related activities at a dam. A change in security conditions could also terminate public access across the dam until such time as threat levels decrease. The public will be notified about closures, if possible, in advance, but the crossing is still subject to closing at any time.
