Daily Rules, Proposed Rules, and Notices of the Federal Government
Coastal Marine Construction, INC, on behalf of Pinellas County, FL, has requested a deviation to the regulations of the Dunedin Causeway bridge, mile 141.9, across the Gulf Intracoastal Waterway as required by 33 CFR 117.5: Except as otherwise authorized or required by this part, drawbridges must open promptly and fully for the passage of vessels when a request or signal to open is given in accordance with this subpart. To facilitate the repair of the bascule leaves, one leaf will be required to remain in the closed position upon signal from a vessel, except with a three hour notification for an opening requiring both leaves. This deviation effectively reduces the horizontal clearance of 91 feet by half for vessels requiring an opening. The Mean High Water clearance in the closed position remains 24 feet. Vessels not requiring an opening may pass at any time. This action will affect a limited number of vessels as the ability to use the full 91 foot horizontal clearance is available with a three hour notification. This action is necessary to allow Coastal Marine Construction, INC to conduct necessary repairs the bascule leaves safely and efficiently.
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.
