City Replacing Street Lights | VideoJoel Porter | 4/9/2012
In 2008, the federal government ordered a phase-out of any street lamps that run on mercury vapor. Mercury lamps are no longer manufactured and are considered a hazardous material. In 2009, Bismarck began switching to high pressure sodium ballasts.
"We took a proactive approach and just did it in a regulated routine maintenance move through the city instead of doing it piecemeal one light at a time as they were burning out," said Director of Service Operations Jeff Heintz.
Heintz says he expects contractors will have all the remaining bulbs to be replaced by the summer. The city is finishing the switch-out nearly a year ahead of schedule.
