The Sonoma-Marin Area Rail Transit District requested to secure the Blackpoint Drawbridge, mile 0.8, Petaluma River, in the closed-to-navigation position on 29 August 2005, during daylight hours for bridge repair. The drawbridge provides unlimited vertical clearance in the full open-to-navigation position, and 7 feet vertical clearance, above Mean High Water, when closed. The drawbridge is normally maintained in the fully open position, except for the crossing of trains or for maintenance, as required by 33 CFR 117.187.

The proposed work was coordinated with waterway users. From 6:30 a.m. to 8 p.m. on Monday, August 29, 2005, the drawspan may be secured in the closed-to-navigation position and need not open for vessels. If safe to do so, a vessel can pass through the bridge during this period. The drawspan will be able to open in an emergency with a one-hour advance notice. The drawspan shall resume normal operations after 8 p.m. on August 29, 2005.

In accordance with 33 CFR 117.35(c), this work will be performed with all due speed in order to return the bridge to normal operation as soon as possible. This deviation from the operating regulations is authorized under 33 CFR 117.35.
