Columbia Gas of Pennsylvania Inc. will invest $6 million in pipeline improvements along the Route 51 corridor, with construction set to begin in the area on Monday, officials said this week.

As part of the Pennsylvania Department of Transportation District 11's upcoming road improvement and bridge repair project at the Route 51 and Route 88 intersection, Columbia Gas will replace approximately 2,400 feet of existing steel pipe along the Route 51 corridor in Pittsburgh and Overbrook, according to a statement released on Friday. Columbia Gas' portion of the project is expected to be completed by the end of September and will benefit approximately 24 customers.

The pipeline improvement project will involve state Route 51, Fairhaven Street, Provost Road, Ivyglen and Underwood streets and Stewart Avenue. Work will take place Monday through Friday from 7 a.m. to 7 p.m., with possible Saturday work. No restrictions are expected on Route 51 at this time.

For a small duration of the project, night work will take place Sunday through Friday from 7 p.m. to 6 a.m.

Due to the location of the pipe being replaced, as well as the roadway and traffic conditions at this site, single lane closures and full road closures during working hours are possible. For six weeks, there will be a permanent detour around Fairhaven Road as traffic approaches from state Route 51 southbound. There will be daily road closures on Provost Road between Stewart Avenue and Weyman Road for approximately two weeks of the project. Detour signs will be clearly set in place to direct vehicles around all closures.

The construction work will require a temporary interruption of natural gas service for individual customers while their service is connected to the new gas main, officials said. Columbia will make personal contact with customers prior to temporarily interrupting service and to schedule service restoration. All Columbia Gas of Pennsylvania employees and contractors carry identification cards bearing their name, photograph and identification number.
