SUPPLEMENTARY INFORMATION:

The Chelsea Street Bridge, across the Chelsea River, mile 1.2, between Chelsea and East Boston, Massachusetts, has a vertical clearance in the closed position of 7 feet above mean high water and 17 feet above mean low water, and 175 feet above mean high water in the full open position. The bridge opens on signal at all times as required by 33 CFR 117.593.

The waterway is transited predominantly by commercial operators delivering petroleum products to facilities located upstream from the new bridge.

The lift span at the new bridge is out of skew and must be adjusted to prevent damage to the operating system. The adjustment maintenance requires the bridge to remain in the closed position for four hours.

The upstream oil facilities were all advised regarding the four hour closure. No objections were received.

Under this temporary deviation the bridge may remain in the closed position from 8 p.m. through midnight on February 21, 2013.

In accordance with 33 CFR 117.35(e), the bridge must return to its regular operating schedule immediately at the end of the designated time period. This deviation from the operating regulations is authorized under 33 CFR 117.35.
