Gilmerton Bridge/Southern Branch Closure:

ICW Waterway Restrictions and Closures in Norfolk Area:
…September 5 to 14, 2012: The USCG is proposing to close the Elizabeth River in Norfolk, Portsmouth, and Chesapeake from the Eastern Branch of the Elizabeth River to the Gilmerton Bridge (36.775082° -76.294999°) at the ICW Mile 5.8 for the move and installation of the new Gilmerton lift span. This closure, which was originally scheduled to begin on July 31st, is anticipated to last five days in the following manner: 12 hours for the move of the bridge span which requires closure of the Eastern Branch and Southern Branch of the Elizabeth river; and the subsequent 4.5 days after the move for the installation of the same which will require closure of the Southern Branch of the Elizabeth River at the Gilmerton Bridge, ICW Mile 5.8. The five day closure is anticipated to occur within the dates of September 5th to the 14th; during this time no vessel traffic will be permitted to transit this area until the bridge span is installed…
Update: AIWW - Elizabeth River Southern Branch - Gilmerton (lift) Bridge - NPRM issued; proposes a temporary safety zone during new center span float-in and span construction effective from 0600 on 5 through 9 SEP 12; with inclement weather dates of 10 to 14 SEP 12. Comment period ends 14 AUG 12. (5th District LNM 31)

Floating Bridge Proposed to Replace Minim Creek Ferry (AICW Mile 411.4):
The Coast Guard is processing a Draft Environmental Assessment for the construction of a floating swing span bridge and is now soliciting comments from mariners and other public interests In regard to any proposed adverse impacts that may affect the environment. The proposed floating swing bridge crosses the Atlantic Intracoastal Waterway at mile 411.4, from the mainland to Cat Island/South island, just south of Winyah Bay, south of Georgetown, Georgetown County, South Carolina (Lat: 33 15’02.84”N & Long: 79 16’07.50”W). The proposed floating swing span bridge will replace an existing ferry system at this waterway location. The proposed swing span will remain in the open-to-navigation position along the Cat Island shoreline until needed to allow vehicles to cross the waterway. It will take the swing span approximately 3 minutes to swing close, 2 minutes for each vehicle to cross the bridge and approximately 3 minutes to reopen the swing span to navigation. The Draft Environmental Assessment document is available at the following web site: http://www.navcen.uscg.gov/?pageName=pnBridges&Active=1&region=7. Solicitation for public comments will end on August 31, 2012. The bridge project manager is Mr. Brodie Rich can be contacted by telephone at (305) 415-6736 or by e-mail at Brodie.E.Rich@uscg.mil.
