The Newlands Cross flyover on the N7 will be officially opened to traffic tomorrow.
Minister for Transport Paschal Donohoe officially opened the road yesterday.
A time-lapse video has captured the construction process that went into completing the flyover.
The upgrade will provide a continuous free-flowing route between the M50 Red Cow interchange and Limerick, Cork, Kilkenny and Waterford.
An estimated 85,000 vehicles pass through Newlands Cross every day, making it one of the busiest junctions in the country.
