SAO PAULO, April 11 (Xinhua) -- Sao Paulo will remain on the Formula One schedule until at least 2020, local officials announced on Friday.

The Interlagos circuit, whose previous F1 contract expired in 2015, will also undergo major redevelopment work, Sao Paulo's prefecture said in a statement.

Works will include a complete resurfacing of the track, new corporate boxes and an upgrade of the existing paddock and pit-lane areas.

"The changes will leave an important legacy for Interlagos, which is going to be better, more beautiful and modern," the statement said.

The announcement ends speculation of Formula One's possible return to Rio de Janeiro, which featured on the Grand Prix circuit in the 1980s.

This year's Brazilian Grand Prix, the season's penultimate race, will be held on Nov. 9.
