Bay View Road in Port St Mary will open today after a land slippage on the 11th January forced it to close.
Around 50 tonnes of earth was washed away in the area of Happy Valley.
Repair work to improve the road has taken place and it's hoped it will reduce the risk of future damage.
There will be further work on the road in a few weeks time to ensure the long term stability but the section that was closed off will re-open today.
An investigation into what caused the landslide is on going.
