The Department of Transportation has enacted a cost saving measure, asking 555 road repairers to stay home one day every two weeks, which means that potholes are taking longer than usual to be filled. The result is 22,000 fewer hours of roadwork, saving the department $1 million. It took an average of 3.65 days to fill a pothole in January 2011, compared to 1.42 days in January 2010. Yet a DOT spokesman maintains that the total sum of manpower hours is consistent with last year, due to personnel changes.  More than 45,000 potholes have been filled since the big December snowstorm, and a spokesman for the mayor maintains that the department is working efficiently and filling more potholes this year than last.
