Columbia Gas is starting a $1.5 million project that will upgrade its pipeline through York.
The natural gas company began preliminary work Tuesday, making line markings and preparing the site for work.
Construction is expected to begin next Tuesday or Wednesday and will replace more than 8,700 feet of existing pipe on West Market and Monroe streets between South Fayette and South Oxford streets.
The work may also include some surrounding streets and could cause temporary lane closures.
Construction will occur from 9 a.m. to 3 p.m. Monday through Saturday on West Market Street and 7 a.m. to 5 p.m. on other streets, according to a company news release.
"The project is scheduled to last through the end of the year, though that could change as the project progresses with weather and seasonal conditions," said spokeswoman Rachel Ford.
Some work will require a temporary interruption of natural gas service for individual customers while their service is connecte to the new gas main. Columbia Gas will make personal contact with customers prior to shutting off service and to schedule service restoration, she said.
All company employees and contractors carry identification cards showing their name, photograph and identification number, according to the news release.
