Scottish Water is to erect temporary traffic lights at the Mauricewood Road junction with the A702 ahead of planned housing development in the Penicuik area.
The developer is planning to build a roundabout to serve the new housing development.
Before the roundabout can be installed and to help facilitate the development, Scottish Water is required to carry out some work to divert water pipes.
While much of the work will take place away from the road, it is necessary to carry out some work at the junction of the A702 with Mauricewood Road.
This will require traffic management in three stages – with each period expected to last around a week.
The first stage, which begins on Thursday, February 18, will allow for the installation of temporary crash barriers.
The second stage involves laying a new pipe and the third stage involves the removal of the crash barriers. Scottish Water will endeavour to carry out each phase of the work in order to facilitate this development as quickly as possible. Dates for these stages will be confirmed in due course.
Community team manager Bill Elliot said: “We are grateful to customers and motorists for their patience and understanding during this work which Scottish Water is required to carry out to facilitate planned development in the area.”
