A total of seven night-time road closures at and near the A46 Riseholme Roundabout will be in place during the middle and end of August.
The dates for these night-time closures are as follows (subject to suitable weather):
- Thursday 13 and Friday 14 August at the Riseholme Road roundabout junction
- Diversion route via A46/B1182 Nettleham Road/Longdales Road/B1226 Riseholme Road, or vice versa
- Monday 24 to Friday 28 August for five evenings at the roundabout's A15 junction
- Diversion route via A46/A57/A156 to Marton/A1500/A15, or vice versa
The temporary 30mph speed limit and lane narrowing measures currently in place will also remain for the rest of the scheme.
Cllr Richard Davies, executive member for highways, said: "We're now at the stage where it's essential to close parts of Riseholme Roundabout so reconstruction and surfacing works can be carried out safely and efficiently.
"This will inevitably cause some disruption for people that regularly use this route and those that live nearby. However, the negative effects caused by closing sections of the roundabout during the day would be massive.
"I want to reassure everyone affected that we'll be doing our absolute best to keep disruption, including noise, to a minimum.
"This project is continuing to progress really well and we're still on track for the having the roundabout fully back open this autumn."
The £4.2m improvement project is being funded via £2.4m from the Greater Lincolnshire Local Enterprise Partnership and £1.8m from an Integrated Transport Grant.
