Viking Riverboat Locking Through at Lock and Dam 15 at Rock Island, Illinois

This is a simple, quiet video of unique Mississippi river event – a Viking Riverboat Cruise Ship passing through the lock at Lock and Dam 15 at the Rock Island Arsenal Army Base in Rock Island Illinois, and under the Government Bridge connecting Davenport Iowa and Rock Island, Illinois. What makes this lock unique is that it is located under a two-deck iron and steel bridge. The challenge here is that many ships, including this Viking ship, are too tall to pass under the bridge which means the bridge must open to allow the ship to move through the lock. However, unlike the more well-known draw bridge, which rises vertically, the government bridge is a turnstile-type, or swing bridge, that rotates 90 degrees to allow the boat to pass.
