That's not much to go on. Maybe "Sorcerer" (1977)
"Outcasts of different backgrounds are forced by fortune to work in a
remote oil drilling operation in South America. When fire breaks out
of control the outcasts are given the opportunity to earn enough money
to get out by transporting two crates of unstable dynamite through
miles of jungle in ancient trucks in this taut thriller. One stunt
features two trucks attempting to cross a rope bridge over a raging
river. "
