A737 Dalry Bypass
You are here
Description
This weathering steel bridge with a width of 19 meter spans 250 meter, 14 meter above the valley. The structure crosses the River Garnock and the Ayr-Glasgow railway line. The bridge deck was assembled and launched over the valley in two phases. This enabled a safe way of working and a minimal disruption of the railway.
The A737 Dalry Bypass scheme is commissioned by Transport Scotland. Victor Buyck works with Farrans Roadbridge jv on this project.
Main girders, cross girders and side girders have been manufactured in Eeklo, Belgium and were transported to the site with trailers and ferries. Once the pieces arrived on site, they were lifted in place and consequently welded or bolted to the existing pieces. Temporary steel structures (in blue) allowed to assemble and launch the bridge. We installed more than 10 000 bolts and 120m of site welds to build the 1150 T viaduct.
