Work has begun on upgrading the Interlagos circuit in Sao Paulo, Brazil, as part of an $80 million (£58m) redevelopment programme.
The circuit will see a brand new pit and paddock complex constructed at the same site as the current facilities, an improved pit entrance, new grandstands and a complete resurfacing of the track surface.
Initial plans had seen the pit complex relocating, but after an in-depth study, officials found it would have changed the flow of the circuit.
Therefore preliminary works to the pits will be done prior to the 2014 race later this year, before the existing structure will be knocked down and a new, larger facility built in its place ahead of the 2015 race.
Track and pitlane resurfacing has already begun, whilst a new drainage system will also be completed ahead of the November race.
The upgrades are part of deal for Interlagos to continue as Brazil’s home of Formula 1 until 2020. The city of Sao Paulo is financing the works.
