GEORGIA – ATLANTIC INTRACOASTAL WATERWAY – BEAUFORT RIVER TO ST. SIMON SOUND – WILMINGTON RIVER CAUSTON BLUFF (ISLAND EXPWY) SR 26 BRIDGE: Bridge Replacement / Temporary Deviation- UPDATE
Prince Contracting has been contracted by the Georgia Department of Transportation to replace the CR 787 (Island Expressway) Drawbridges across the AICW (Wilmington River), at mile 579.9, in Savannah, GA. The bridge replacement project will replace the existing dual span bascule bridges with dual span high level fixed bridges. When completed, the new high-level fixed bridges will provide a horizontal clearance of 170 feet between the fender system and a vertical clearance 65 feet at Mean High Water (MHW). The project has started and is estimated to be completed November 2021. Work barges and associated equipment may be located in the vicinity of the bridge but will not impede the navigational channel. All mariners are requested to use caution when transiting the area. For additional waterway information, please contact Coast Guard Marine Safety Unit Savannah at (912) 652-4353.
