A £310,000 scheme to improve the A368 in Banwell and Sandford is set to start on Monday 9 November.
The works will include carriageway resurfacing, gully emptying, minor drainage works and vegetation removal.
The scheme, which is due to be finished by Friday 20 November, will be completed using a road closure at night between 8pm and 6am.
Key local businesses including Thatchers have been consulted on the scheme and no work will take place on Saturday 14 and Sunday 15 November.
Cllr James Tonkin, executive member with responsibility for highways and transport asked people to be patient during the works.
A signed diversion route will be in place and the work will be carried out in line with social distancing rules.
