The €50m project will involve construction of two new interchanges and the replacement of an access bridge. One of the interchanges, at Osberstown, will facilitate a new bypass of Sallins. The other, south of and replacing the current Junction 10 at Newhall, will provide more efficient access both to Naas and Newbridge and eliminate chronic congestion on the off-ramp at the present Junction.
The third lane on each side will be made mostly by eliminating the grass centre margin, minimising the necessity for compulsory purchase of land.
The project is expected to be ready for funding and planning applications next year. If all goes well, it could be completed in 3-4 years from now.
