A new gas line was being put in near Butterfield Road and Route 60, and in order to do that, crews had to cap off the old one and burn off excess natural gas.
Flames could be seen shooting from the pipe, which is 40 to 50 feet tall, making them visible to motorists. The burn was not near any traffic, however.
Authorities want those in the area to know the burn is under control and there is no cause for alarm.
The effort could be under way for a few hours.
