Contractors are still working to finish up three city-funded waterline replacement projects in Billings.
COP Construction crews have been working for much of the summer to replace water mains on South 27th Street and Montana Avenue and water and sewer lines on a West End portion of Grand Avenue.
The South 27th Street project began June 18 and will take at least another three weeks, according to Randy Straus, a staff engineer in the city's Public Works Department.
That project involves installing a new 12-inch water main from Fifth Avenue South to State Avenue, and extending lateral lines on the west side of 27th. Traffic on the affected part of South 27th is currently restricted to one lane in each direction on the east side of the median.
The Montana Avenue water main replacement began July 9 and should wrap up about the first week of November, Straus said.
Two COP crews have been working on that project, one inching east from North 31st Street and the other working between north 22nd and 18th streets. The latter portion is done, Straus said, so the only incomplete stretch is between 26th and 22nd streets.
Also, the project jumped over the intersection of Montana Avenue and North 27th Street, which will be worked on toward the end of the entire project.
The third project is on Grand Avenue between 30th and 28th streets west. Straus said the sewer main has already been installed, and a crew is working to complete the water line.
Traffic is being routed to the north side of Grand while work proceeds on the south side of the street. That project began on July 23 and should be done in about two weeks, Straus said.
