Mrs Chalmers said the roundabout would eliminate dangerous manoeuvres in which motorists turning right out of Minden Rd had to make the turn in two bites, parking in the middle of SH2 until there was a break in the traffic heading towards Tauranga.
Motorists turning left out of Te Puna Rd had to be aware that Minden Rd traffic was waiting in the middle of SH2 for the same gap in the traffic. It was not unusual to see broken glass and bent signs at the intersection, she said.
Mrs Chalmers had noticed a big build-up in traffic over the last 10 years as town moved out into the countryside. " ... it is murderous to get out, people are ducking and diving."
Another Te Puna resident, who asked not to be named, welcomed the safety improvement although she wondered what the impact would be on traffic flows along SH2 when they had to give way to local traffic.
The agency's Bay of Plenty highways manager, Niclas Johansson, said the roundabout was a key part of the SH2 Safe System Northern Corridor project. More than $5 million worth of safety improvements will be installed along the corridor over the next two months including guard rails and wide centre line treatments. They will also look at realigning sections of road to improve sight distance and address speed limits.
Mr Johansson said the agency would work with council, iwi, land owners and other key stakeholders over coming months on the consenting and designation process for the roundabout.
