A temporary diversion will be in place on Street 213 in the Umm Enaig area of Al Khor from Friday for a month.
The diversion is for about 150m in both directions, Ashghal said on Wednesday. 
During the period, traffic in both directions will be diverted to a temporary diversion road that is parallel to the closed road (as shown on the map).
The traffic change is required to enable works related to laying sewer rising mains of Al Thakhira sewage treatment works, transfer pumping station and associated pipelines.
Ashghal will install road signs to advise motorists of the closure.
The authority has requested road users to abide by the speed limits, and follow the road signs to ensure safety.
