​Voters have strongly backed the Andrews government's sky rail project as part of its policy to remove dozens of level crossings.

A new ReachTEL poll commissioned by The Age found 60 per cent of Victorians "support the use of sky rail to remove level crossings".

Just 22.4 per cent oppose it, with a 18 per cent undecided on the plan, which will elevate the track between Caulfield and Dandenong, removing nine congested level crossings.

Sky rail is part of Labor's popular election policy to remove 50 level crossings over eight years. Work on the $1.6 billion project, which will also see five stations rebuilt, is due for completion before the next state election in 2018.
