Force one's way through American street (6)
I believe the answer is:
thrust
'force one's way' is the definition.
'through american street' is the wordplay.
'through american' becomes 'thru' (US informal spelling of 'through').
'street' becomes 'st'.
'thru'+'st'='THRUST'
(Other definitions for thrust that I've seen before include "Force engine generates" , "Push suddenly forward" , "Push powerfully; stab" , "Lunge forward" , "Sudden lunge or attack" .)
