Towing over the Milau Viaduct in France

Hi Everyone, hope you all had a great Christmas! I was wondering if anyone had towed over the Milau Viaduct in France as i had read that it is difficult due to the gradient both up and down if towing a large Van? My Van is a Swift Challenger SE 580 with
a MPLW of 1516kg and i tow with a VW Tiguan 2.0 TDI 4X4 with a kerbweight of 1655kg and usually pack most of my holiday kit in the back of the car to keep the Van as light as possible!  Your advice would be greatly appreciated.

Kind Regards to all
