Council transportation manager Martin Parkes said the council was looking forward to getting this project under way.
The council would be working to minimise any issues for road users and people living and working in this area, Parkes said.
To ensure that the affected community was kept up to date, the council would issue regular e-newsletters and media releases.
Western Bay of Plenty road policing, Senior Sergeant Craig Rawlinson said it was tempting to have a good look at what was happening with the works, however, anything that took a driver's attention away from the road could be a potential hazard.
"Therefore we ask drivers to actively contribute to the prevention of further delays by keeping their eyes on the road and avoiding rubbernecking, which could potentially slow down the traffic flow."
The council paused the project last month, but voted unanimously on August 6 to unpause it after hearing assurances from transport modelling experts it would not make congestion worse.
Elected members heard there might be a modest time saving on average for evening commuters - less than a minute - but that the project would mainly make journey times less variable.
Principal transport planner Bruce Robinson said at the time there would be little impact on journey times without releasing the Hairini Bridge bottleneck.
Stage 1 includes:
• Widening the road with two continuous southbound lanes from Fraser St, merging to one lane after Burrows St to give the 15th Ave/Fraser St intersection a better chance to clear in the afternoons.
• Installing traffic lights at the Burrows St intersection to manage the traffic entering 15th Ave and maintain a safe crossing point for people on foot and on bikes.
• Closing the exit from Grace Rd on to 15th Ave and closing the Turret Rd slip lane to control traffic from these side streets.
• Installing a new shared path from Alexander St to Mayfair St via the new signalised crossing at Burrows St to improve connections for pedestrians, cyclists and other vulnerable road users.
• Developing a new northwest-bound bus lane between Mayfair St and Scantlebury St to improve bus service reliability. While this lane is relatively short, it is part of possible future plans to improve the wider bus network.
The first couple of weeks of the project mainly revolve around setting the site up and beginning preliminary works.
