Work on the Reais 1.53bn ($US 407m) project is due to begin in six months.
The 20km, 22 station line will have capacity for 150,000 passengers a day. The monorail will replace the current suburban line from Calçada to Paripe, benefiting the region's more than 600,000 residents according to the government. The 10 suburban rail stations will be deactivated and reused to provide other services to the community, such as military police stations and service centres.
The project also includes a possible four-station extension through São Joaquim, integrating with the Salvador metro.
Skyrail Bahia, a consortium of Build Your Dreams and Metrorail, was selected to construct and operate the line in May 2018 under a public-private partnership (PPP).
