The water main break responsible for the sinkhole happened early Tuesday morning on South Lowell Boulevard near West Greenwood Place, just north of Highway 285.

About six feet of pipe burst and even more cracked as a result of the pressure. Denver Water told CBS4 at least 13 feet of pipe will have to be replaced.

Crews made the repairs on Tuesday and the repaving project started about 8 a.m. on Wednesday.

The cause of the break is hard to pinpoint but Denver Water said it could be a combination of things that include the age of the pipe, it was installed in the 1950s, the material, corrosion, water fluctuation and a change in temperature.
