The line was originally envisioned to be long and should be opened in three stages. The first section was planned to be a long linking
Congonhas-São Paulo Airport to
São Judas Station, with an initial demand 18,000 passengers per day and construction start in 2011. The second phase, expected to have a demand of 100,000 passengers per day, was originally planned to begin operations in 2015. It should be long and connect the
Morumbi CPTM station and the
Jabaquara metro station. The two sections connect at the future Brooklin Paulista station, forming a "Y". However delays and heritage preservation issues prevented the line from starting construction, leading it to be shelved in 2011. The line was planned to be operated with
CBTC using
Thales SelTrac technology. On 9 June 2014, a concrete support beam collapsed during construction which killed one worker and injuring two others. Completion was scheduled for the start of the World Cup but construction was delayed due to issues with environmental approvals. As a result, the line was delayed until the second half of 2015. Construction stopped October 2015 due to a contract dispute with construction only to be resumed in June 2016. This delay postponed the opening date of the first phase to 2018. Further delays in the construction has meant that the first phase of the line was further postponed from 2018 to 2019. With the financial trouble of
Scomi leading to non-performance in manufacturing the monorail rolling stock, the contract was terminated in 2019. After a short rebidding process it was announced that
BYD will manufacture the rolling stock using their "
SkyRail" platform. On 14 January 2020, a new contract was created, and completion was postponed to 2021 or 2022. In November 2020, after months of legal battles, the Metropolitan Company signed a contract with Coesa Engenharia, owned by Brazilian company OAS, for the conclusion of general construction works. The annual report of the
São Paulo Metropolitan Company estimates the opening of the line on 30 April 2023. Before leaving the state government, Governor
João Doria estimated the opening to January 2024. After another paralyzation in construction works and another resume, the State Metropolitan Transport Secretariat estimated the opening to June 2026. == Stations ==
