Trailblazer, groundbreaker or pathfinder would also have been options in English, at least are close synonyms for pioneer. All have similarities but more literal , I've never heard roadbreaker in English, but you never know what they say in places like Australia, probably a"whackaroo".

Groundbreaker might possibly originate from farming/ploughing or construction in new territory rather than literally making a road. But might be more apt for the OP.
