End Further Info End Preamble Start Supplemental Information


The owner of the bridge, the Connecticut Department of Transportation, requested a temporary deviation in order to facilitate maintenance of the bridge including installation of timber ties, miter rail replacement, and steel repairs.

The Metro-North Bridge across the Mianus River, mile 1.0 at Greenwich, Connecticut is a single-leaf bascule railroad bridge offering mariners a vertical clearance of 20 feet at mean high water and 27 feet at mean low water in the closed position. The existing drawbridge operating regulations are listed at 33 CFR 117.209.

The temporary deviation will allow the owner of the Metro-North Bridge to close the span for openings each week beginning 8 a.m. Monday through 4 p.m. Friday from March 27, 2017 to May 8, 2017. The span will open on signal from 4 p.m. Friday through 8 a.m. Monday, provided 24 hours advance notice is given. The regular operating schedule for the span will be restored April 8, 2017 through April 11, 2017 in order to accommodate a previously scheduled boating event.

Vessels able to pass through the bridge in the closed position may do at anytime. The bridge will be able to open for emergencies. There is no alternate route for vessels to pass.

The Coast Guard will also inform the users of the waterways through our Start Printed Page 13757Local and Broadcast Notices to Mariners of the change in operating schedule for the bridge so that vessel operators can arrange their transits to minimize any impact caused by the temporary deviation.

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