The construction of three roundabouts at Green Island is proceeding on track and on budget.
Work on the $1.8million project to build roundabouts at the intersections of Main South Rd and Brighton Rd, and Main South Rd with the northbound motorway on-ramp and the southbound off-ramp (Westland St), began in March and should be completed in July, weather permitting.
Jointly funded by the NZ Transport Agency ($1.3million) and Dunedin City Council, the contract is being carried out by Dunedin firm Fulton Hogan Ltd.
Dunedin City Council senior transportation engineer Susil Gunathilake said the motorway on-ramp and off-ramp roundabouts were being built first and should be in place by the end of June.
The finishing touches, such as crossing points for pedestrians, paving and landscaping, would be put in place after that, while work started on the Main South Rd-Brighton Rd roundabout, Mr Gunathilake said.
To construct the roundabouts, the road surface had had to be milled and rebuilt in order to be able to sustain the loading of new traffic patterns. In addition, drainage and mud tanks were also being upgraded where necessary.
“We are taking the opportunity to do the work properly. We want it to last,” he said.
“It has been tricky to do the work while minimising the disturbance to traffic and, on behalf of the DCC and NZTA, I would like to thank motorists for their patience.”
Fulton Hogan Construction Division manager Paul Jamison said the works had been going well from the construction perspective.
“The boys put in a big week last week, with night operations to minimise the inconvenience to motorists as much as possible,” he said.
“Some nights we have had 20 guys working across different parts of the project.”
The key had been the huge amount of planning done before work began, and ongoing communication.
Greater Green Island Community Network worker Leanne Stenhouse said motorists were managing very well and had appreciated regular updates on progress.
Mr Jamison agreed that motorists’ behaviour had generally been good, although “it’s fair to say [people] took a bit of time to get used to it”.
“We have had a significant presence in terms of signs and traffic control.”
The next major phase of the project would start in mid-June, when work on the Main South Rd-Brighton Rd roundabout would begin with milling the road surface down to the aggregate, he said.
