Straight from the mouth of Costal pilot:MD/VA/DC - POTOMAC RIVER - WOODROW WILSON BRIDGE - BRIDGE INFORMATIONMariners are advised that construction of the new Woodrow Wilson Memorial Drawbridge across the Potomac River, mile 90.7, between the City of Alexandria, Virginia and Oxon Hill, Maryland is ongoing until 2009. Excessive speed and wake by boaters may cause serious or fatal incidents to the Bridge project. It is crucial that mariners obey the speed restrictions and eliminate wakes through the work zone, due to the sensitive and precise nature of the work and for worker safety. A temporary floating/sliding bridge will be in place in the waterway during drawbridge construction until further notice. There will be intermittent channel restrictions as a result of the floating bridge, as well as the need to further restrict use of Federal channel on an intermittent basis for crane barge positioning. During such times, vessels will be able to use the existing temporary auxiliary channel (east of the Federal channel under a fixed span portion of the bridges), made available to vessel traffic with a vertical clearance of 45 feet or less (with a horizontal clearance of 130 feet and a depth of 22 feet at Mean Low Water). Mariners transiting this part of the waterway may do so, but at their own discretion. Clearances and opening procedures for the existing Woodrow Wilson Bridge remain unchanged. Mariners are urged to listen to Broadcast Notices to Mariners for updates and to use extreme caution when transiting this area for work barges, exposed piles, and anchor buoys. In late 2006/early 2007, for approximately 5-6 months, a vertical clearance restriction of 70 feet or less is anticipated during the construction of the inner loop (I-95/495) bascule bridge.

This safety zone will be enforced from 9 p.m. to 11:30 p.m. and is necessary to control vessel traffic for safety of life and property on navigable waters during the event. The effect will be to restrict vessel traffic on a portion of the Upper Potomac River. The fireworks barge will have a sign on its port and starboard sides labeled FIREWORKS--DANGER--STAY AWAY to provide on scene notice that the safety zone will be enforced. This notice will consist of a diamond shaped sign 4 foot by 4 foot with a 3-inch orange retro reflective border. The word "DANGER'' in 10 inch black block letters centered on the sign with the words "FIREWORKS'' and "STAY AWAY'' in 6 inch black block letters above and below the word "DANGER'' respectively on a white background. Vessels may not enter, remain in, or transit through the safety zone during the enforcement period unless authorized by theCoast Guard Captain of the Port or designated Coast Guard patrol personnel on scene. All persons and vessels shall comply with the instructions of the Captain of the Port or the designated on-scene-patrol personnel, and upon being hailed by siren, radio, flashing light or other means, the operator of a vessel shall proceed as directed. Other Federal, State and local agencies may assist these personnel in the enforcement of the safety zone.
