So I was researching Cartegena when I came across a You Tube time-lapsed video condensing the 8 hour canal crossing into 2 minutes.
The ship is the Radiance of the Seas (RCCL) and the video is from May 8, 2003 prior to the completion of the Centennial Bridge but you clearly get to experience (very quickly) going through the canal as the Magic just did ending on the Pacific side going under the Bridge of Americas.
It is a different perspective and pretty cool.
