The reopening is part of a planned two-week festive shutdown of GAR construction works
The road will be closed off again to pedestrians and motorists from January 4.
The traffic lights between Jessops Lane and Glebe Farm will also be removed during the festive period.
The coned-off Lane at Mapperley Plains will remain the same throughout the shut down
A spokesman for Nottinghamshire County Council said: “On behalf of the GAR team, we would like to wish you all a very Merry Christmas and a Happy New Year!
Phase two of the Lambley Lane Road closure has been brought forward to January 4, 2021 and will see a section of the road closed 24 hours a day, seven days a week and will replace the current daytime weekday closure.
Works on this section of the project have been brought forward following good progress on site.
Please note that there will be no vehicle or pedestrian access during the closure, and a diversion route will be in place, details of which can be found on our construction page.
