With work on this project now underway, new details are available on how ongoing works will affect residents, businesses, and drivers.
Jetesh Bhula, Regional Manager Infrastructure Delivery, says a single directional road closure will be in place on State Highway 6 from mid-July.
"From Monday, 15 July to early December, a section of State Highway 6 outside the Marlborough Airport will be closed in one direction to eastbound traffic with local road detours in place."
"It will be the same approach we used for the recent State Highway 6 Bells/St Leonards Roads roundabout works. We're prioritising traffic from Blenheim to the airport," Mr Bhula says.
"The roundabout construction, which will improve traffic flow and safety, will begin in August once services are relocated."
The final stage in December will involve four nights of road closures for final sealing work on the Bells/St Leonards Roads and the Tancred Crescent roundabouts.
"Like the Bells/St Leonards roundabout, the new roundabout will be built over four stages, with the final stage to be completed by mid-December. We will update the community on how this work will affect them as it progresses."
"We thank everyone for their patience while this work is carried out, and we urge people to factor extra time for their journeys, especially when traveling to the airport," Mr Bhula says.
