Dilma Rousseff promised in 2011 the doubling of 73 km of the highway, between Indaial and Navegantes, in addition to the concession to the private sector of the Santa Catarina section. The work started only in 2013, and had just over 9 km duplicates delivered, in 2019 alone, under the government of
Jair Bolsonaro. The first 8 km of track were launched in June 2019, from km 22 to km 30, between the municipalities of Ilhota and Gaspar. In August 2019, 1.3 km were delivered between 0.00 and 18.61 km, between Navegantes and Ilhota. The expectation is to deliver the 73 km doubled in 2022. With the delivery of the Mafisa Clover (one of the most complicated and expensive sections of the project), 23.8 km of duplications had already been released by August 2020. ==References==
