A consortium of Comsa and Tiisa Infrastructure and Investments have completed construction of the São Paulo Metro driverless Line 4 phase 2. The opening of the full line has been staggered, with sections of line opened ahead of the completion of intermediate stations.
The second phase of the project has consisted of the construction of two additional kilometres of tunnel, the commissioning of four new stations at Higienópolis-Mackenzie, Oscar Freire, São Paulo-Morumbi and Vila Sônia, the construction of three emergency exit shafts, and the execution of an urban bus terminal.
Phase 1 of the line initially opened in May 2010, with six stations in operation at Butantã, Pinheiros, Faria Lima and Paulista, República and Luz.
Phase 2 comprised the completion of the two-station western section of the line from Butantã to Vila Sônia, which was already used by trains travelling to and from the depot, together with the completion of three intermediate stations on the initial operating section between Butantã and Luz. Four Phase 2 stations have been opened in stages, including Fradique Coutinho in November 2014, Higienópolis-Mackenzie in January 2018, Oscar Freire in April 2018, and São Paulo-Morumbi in October 2018, with Vila Sônia yet to open.
When fully complete, the 12.8km line will have 11 stations, connecting the Luz region in the centre of São Paulo to the Vila Sônia neighbourhood, in the southwestern zone.
A consortium of Isolux-Corsan and Corvium was awarded the Phase 2 contract in 2012, but the agreement was terminated in July 2015 after the contractor failed to complete the works on schedule. Construction of one of the stations, Fradique Coutinho, was completed before the contract was terminated.
