Mrs Kells, who organised a 1370-signature petition to the New Zealand Transport Agency ((NZTA), told the Dannevirke News she was excited to see work getting under way.
NZTA regional highways manager David McGonigal said the project will help support the local economy, with Dannevirke-based subcontractor Morris and Bailey supplying the aggregate and concrete work for the culvert. The project will be constructed by Stringfellows from Palmerston North.
"It's great that we're able to call upon the local workforce to help build a bridge they'll be using more than just about anyone," he said.
"It may be a peaceful area, but this is a busy highway which warrants a safe, modern bridge to take it well into the 21st century.
"Five thousand vehicles use this route every day, and one in seven is a heavy vehicle. Once replaced, motorists, cyclists and trucks will be able to share the bridge without holding their breath or gritting their teeth.
"The new bridge will provide safer, more comfortable trips for all road users, while supporting economic activity, especially freight travelling between the ports and the main centres. We are celebrating much more than just the start of a new bridge. We'll be transforming nearly 2km of highway and giving it a full safety makeover."
The project will see the stream pass through a large culvert that will form the new bridge, with the effect that motorists will hardly know they have just crossed a bridge.
Mr McGonigal said widening the highway and bridge will have substantial safety benefits, helping to reduce the risk and severity of crashes.
"By straightening the highway we will reduce the chances of people losing control on the curves and by widening its shoulders we provide room for motorists to correct if they make an error.
"The extra width will also provide breathing space for cyclists. The new bridge won't just be a little bit wider; it will be much wider - going from less than 6m of road width to around 10m - including spacious shoulders cyclists can ride safely in."
The new bridge/culvert will be built to modern seismic standards, with the ability to withstand a large earthquake.
