Daily Rules, Proposed Rules, and Notices of the Federal Government
The City of Tacoma has requested to place the Murray Morgan Bridge (South 11th Street Bridge) in the closed or down position and to not open the bridge for vessel traffic to facilitate a major rehabilitation project on the bridge. The Murray Morgan Bridge crosses Thea Foss Waterway (previously known as City Waterway) at mile 0.6, at Tacoma, WA. The Murray Morgan Bridge is a vertical lift bridge. During this deviation the bridge will be placed in the closed or down position. There will be a debris containment system attached to the underside of the bridge for the duration of construction activities. A minimum vertical clearance of 57 feet above mean high water will be provided beneath the bridge and the attached debris containment system, at all times during the deviation period. Vessels which do not require a bridge opening may continue to transit beneath the bridge during this closure period. Under normal operations the bridge operates under 33 CFR 117.1063 which requires a two hour notice for an opening and allows the bridge to remain closed during morning and afternoon rush hours. This current deviation states the lift span of the Murray Morgan Bridge across Thea Foss Waterway, mile 0.6, need not open from 8 a.m. on November 10, 2012 through 8 p.m. December 21, 2012; except as otherwise outlined in this article and through ongoing coordination with waterway users. During this deviation period the bridge will be placed in the open position from 8 a.m. November 22 through 8 p.m. November 25, 2012 and from 8 a.m. December 8 through 8 p.m. December 9, 2012.
In accordance with 33 CFR 117.35(e), the drawbridge 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.
