A major concrete pour at both ends of the Estuary Bridge on the Hawke's Bay Expressway over the next couple of days could result in delays up to 10 minutes.

A spokesman for the New Zealand Transport Agency said while contractors had been working around peak traffic times to reduce delays there was no option but to reduce stretches of the expressway at the bridge to one lane.

"Obviously there is a period of time when we can have no traffic travelling over these newly poured areas to allow them to set," NZTA journey manager for Napier Oliver Postings said.

"To enable this the bridge will need to be reduced to a single lane for long periods of time."


That time would include peak hour times in the mornings and afternoons and contractors would be using stop-go signalling rather than temporary traffic lights to manage traffic, with motorists advised to allow for an extra 10 minutes travelling time on the stretch.
The Estuary Bridge is one of three bridges on SH2 where work is taking place and where delays can be expected.

Contract crews are also working on the Mangaturanga Bridge, 2km North of Raupunga and the Ohinepaka Stream Bridge and rail overbridge, 10km West of Wairoa.
Speed restrictions and temporary signalling are in place at both.

Seal widening and some guard-railing work is also under way at the north side of the Mohaka Hill, the north side of the Devil's Elbow and at the Mohaka Viaduct.

On SH2 south between Napier and Hastings motorists are advised the shoulder section of the road is closed off between Awatoto and Clive as cyclepath work is carried out.
No delays are expected.

There are however likely to be delays up to five minutes on SH38 between Wairoa and Waikaremoana as bridge replacement work takes place at Mangahohi near Ohuka as well as around various sites between Wairoa and Frasertown as tree felling takes place near power lines.
