Foundations for the new Whanganui-Upokongaro cycleway bridge could be constructed before Christmas, Whanganui District Council project manager Rick Grobecker says.
Its prefabricated steel parts were made by Eastbridge in Napier, and are being assembled on trestles in a site cleared for them on Papaiti Rd.
The abutments for the bridge to rest on are being prepared on both sides of the Whanganui River.
On the Upokongaro side the abutment will be concrete with piles while on the Papaiti side the soil is soft and potentially subject to liquefaction.
The abutment there will be built up from layers of compacted soil, with geofabric between them. It will be faced with rock armour, to protect it from erosion.
