You can clear this fence and run directly to the end in this level.

I feel like this might even be an intended skip, given the positioning of the boxes near that fence. Either way, a nice lil timesave for all categories. This is faster than waiting out the mission and failing for any%. It is a pretty easy skip to do. If you mess up the first try, you can run over to the light and get a lil more time for another attempt.
