The Navy confirms that "tens of thousands" of gallons of jet fuel leaked at Naval Air Station Oceana, shutting down part of London Bridge Road on Thursday. Northbound and southbound London Bridge Road between International Parkway and Virginia Beach Boulevard is currently shut down. Traffic is being diverted to International to Lynnhaven Parkway. The Navy says a significant amount of JP-5 jet fuel leaked from a tank at the NAS Oceana Bulk Fuel Farm some time overnight. The spill was discovered and contained on base at about 6:30 a.m. Some of the fuel spilled into a water-filled ditch outside the perimeter of the base. The Coast Guard, Navy, and Virginia Beach Public Works are working to contain that portion of the leak, but it could take up to 48 hours to be fully cleaned up. No injuries are reported, and a Navy public affairs officer tells 13News Now that the fuel spill has not caused an impact on aviation operations. Virginia Beach Police say motorists can expect the road to remain closed for several hours. The cause of the spill is under investigation.
