The giant 1,550 tonne bridge was constructed on a site adjacent to the N7 and manoeuvred into place using specially imported heavy lift mobile jacking equipment during the night of 7th October. The bridge, which is a Bowstring Arch design, has a suspended deck which will accommodate two-way traffic, cycle-lanes and footpaths. It has a total span of 60 metres and is 20 metres wide.

The Bowstring Bridge will connect the N7 eastbound and Monastery Road (Clondalkin) with the Luas Red Cow Stop and Park & Ride Facility. When it opens to traffic in approximately 8 weeks time it will mean the end of the traffic signals at the N7/Monastery Road Junction so enabling further free-flow movements at the new M50/N7 (Red Cow) Free-flow Junction.

The final traffic layout at the M50/N7 Junction is expected to be in place by the end of December 2008. The Bowstring Bridge is all part of Phase 1 of the M50 Upgrade Scheme which is nearing completion.
