Road surfacing will be re-laid during the first week of July.
The works will start on Monday 4 July for two evenings (subject to weather) and will be carried out under night-time road closures.
Karen Cassar, Assistant Director – Highways, said: "Since opening the upgraded roundabout last December, we've noticed that some of the top-layer surfacing doesn’t meet the stringent quality requirements we specified in our designs.
"Quality issues like these sometimes come up after laying final road surfacing in the cold, winter months, so we knew there was some risk when we re-opened the roundabout last December.
"As a result, the scheme’s contractor will be removing and re-laying this top layer of tarmac as part of our contract with them.”
The works will be carried out:
Monday 4 July – A17 Newark (both directions)
- 6pm to 5:30am
- Diversion via A15 south towards Bourne / A153 / A607, and vice versa
Monday 4 July – A15 Lincoln (northbound only)
- 10pm to 12:30am (2.5hrs)
- Diversion via A15 south towards Bourne / A153 / A607, and vice versa
Tuesday 5 July – A15 Lincoln (northbound only)

- Temporary traffic lanes and part-closures to be utilised as required
Karen Cassar added: “These works will inevitably cause some inconvenience, so I want to thank everyone in advance for bearing with us.”
