the German museums are moving a submarine from one to another... and it's going to take 4 weeks on German roads to do that safely

U17 was used by the German Navy from 1973 to 2010 is 160 feet and weighs more than 350 tons, and traveling 31-miles from the Technik Museum Speyer to the Technik Museum Sinsheim. 

A straight shot via the motorway is about 19 miles

Posted because it's very rare that a sub is on city streets, and rare that I have a good reason to post a sub (I dig them because I crewed on 2, the SSN 717 and 759)
