BCP Council is introducing temporary road closures in Poole to allow gas works to be carried out.
Queen Anne Drive will be closed eastbound between Gravel Hill and Montacute Way from July 27 until August 28.
Canford Magna will be closed between Floral Farm and Queen Anne Drive from June 29 until August 14.
The council says only one closure will be in place at a time because the diversion routes would otherwise conflict.
The temporary order also prohibits parking, waiting, loading and unloading within the affected areas.
Emergency service access will be maintained throughout the works, while access to properties will be available where site safety allows.
