Drakes Lane in Charminster will be closed between its junctions with Wanchard Lane and Highfield Close, a distance of around 440m.
The closure has been requested to allow Wessex Internet to install sub-duct and fibre cabling.
These works are programmed to commence from Monday, November 10 until Friday, November 14.
Wessex Internet will publicise the road closure in a number of ways including the placement of information boards on the road in this area to inform the travelling public of the works.
The company will carry out a letter drop to local residents directly affected by the works; and they will sign a vehicular diversion route using the local road network.
A diversion route has been put in place taking a motorist along A352 and Wanchard Lane.
Any queries on this closure should be sent to trafficteam@dorsetcouncil.gov.uk.
