Santa Cruz de la Sierra to Puerto Quijarro highway?

Hello, We're considering to enter Bolivia from Brazil and travel along from Puerto Quijarro to Santa Cruz, stopping on the way in Santiago de
Chiquitos. The "death train" is obvious option, but is there any alternative? I found some information that paved highway has been
complied, if so are there any shared taxies available covering this route? I imagine that this can speed up travel time at least twice.
If you have any information about it please share ;-)

Best regards,
Marcin
