Works to upgrade the M7 in Kildare are expected to be completed by May or June.
That's according to officials at Kildare County Council.
The widening of the M7 began in 2017, and has been causing long delays for commuters.
A section of the M7 has fully reopened after being closed since Friday to facilitate the installation of a bridge.
Traffic can now use the motorway between Naas North and Naas South.
