The construction of monorails is a good alternative for São Paulo as it requires less land expropriation than a subway, according to the city's metro company (CMSP) director of corporate affairs, Sérgio Brasil.
In addition, a subway is four times more expensive to implement than a monorail, state government said in a release. While a monorail costs from 70mn-95mn reais/km (US$40.8-55.4mn), a subway costs 270mn-380mn reais/km.
São Paulo state and city governments are considering changing three exclusive bus lane routes into monorails. "Three lines have been confirmed while another three are still under discussion and have not yet entered the project phase," a CMSP spokesperson told BNamericas previously. The firm intends to complete these projects by 2013.
Implementing bus lanes is less expensive as it costs about 38mn reais/km but it interferes more with traffic, according to the release.
The monorail in São Paulo will run on 12-15m high pillars erected adjacent to wide avenues. In addition to eliminating the costs associated with relocation, these systems are also quicker to build than subways.
Amazonas state capital Manaus has also chosen to implement a monorail which is scheduled to be ready in 2013, in time for the Confederations Cup. Authorities sent the technical design for the new system, which also includes a bus rapid transit (BRT) design, to the cities ministry in October.
