Someone should call Vlad. The Russians made pretty quick work running a new powerline across the Black Sea to Crimea a few years ago.
It shouldn't take weeks. They know where the break is. Dig a hole, splice the line, fill the hole in. Spare no expense working round the clock. Send the bill to the contractor on the bridge project.
Someone probably wants the whole line re-routed from the bridge to the pole to give them more room to work. That would take longer.
I'm waiting for Hank Johnson to observe that the island should just be moved closer to the mainland. ;-)
