Motorists heading south of Rotorua are being advised to drive carefully and expect delays as they go through the Hemo Rd roundabout construction area this week.
A New Zealand Transport Agency spokeswoman said the project's contractor would be moving out from the main roundabout area to start the surrounding tie-in work this week.
That work would be adjacent to the live traffic lanes and might cause some people to slow down, the spokeswoman said.
However, the project is still on track to be finished in October.
A new drone photograph of the site taken at the weekend by Rotorua resident Brian Holden has captured an aerial view of the progress being made at the site so far.
