Denver Water repair crews had a busy night after four water main breaks occurred on the west side of Denver.

Two of the breaks caused traffic delays for morning commuters.

The biggest break happened at Sheridan Boulevard and 17th Avenue. A 16-inch pipe broke causing Denver Water to close one lane of traffic each way on Sheridan between 17th Avenue and 20th Avenue. Repairs will last throughout Thursday and three customers will be without water while the repairs take place.

Another break occurred at Federal Boulevard and 41st Avenue. The break has closed northbound Federal between 41st and 42nd Avenue. The 6-inch pipe break means two residential and two commercial buildings will be without water while repairs are made Thursday.

Denver Water says two additional water main breaks happened overnight in residential areas. The breaks are on 6-inch pipes at 2336 Osceola Street and 3935 West Byron Place, both in west Denver. About twelve customers will be without water while repairs take place.
