Stuck in Chapter 6.....

[Redracer]

i've read all the previous posts and none seem relevant to my query.
i've cleared all enemies and hit all lever switches, one of which was to
unlock the "crate" whatever or whereever it is.
in the attached screencap i'm wondering if i need to get across here
or is it what it seems, an impossible option.
any help getting past this point would be very appreciated.
any screencaps providing where i go from here would be very helpful.

thanks
