Queensway, Shoreline TF Explosions Summary

I have been a bit confused on the various explosion videos that we have seen. It appears that one occured on the Queensway Bridge from police cars chasing Optimus Prime (#1). Another occured on Shoreline Drive also involving police cars (#2). Then there is a tanker explosion (#3), also on Shoreline, at an intersection that occurs when a tanker "tries" to avoid colliding with the smoking remains of cars (no sure if related to previous two booms or not).

The main way to tell (i think) is the #1 is on the bridge (can tell because of the regular spacing of lights on that bridge). #2 occurs next to a sound barrier. #3, other then involving a tanker, occurs at an intersection.
