Carbon emissions have been reduced by 76% since 2012 under the Streets Ahead project, a Sheffield City Council report said.
This translates to a reduction in carbon output from 17,000 tonnes to 4,000 tonnes, largely achieved through the city’s new LED street lightning system, which replaced the old sodium lights.
Traffic signal installations have also been updated, with new extra low voltage LED technology.
Streets Ahead is a city-wide twenty five year highway maintenance contract that is upgrading and maintaining Sheffield’s streets. The contract is worth £2bn.
As of January 2019, 70% of roads and foot ways in Sheffield have been resurfaced under the project, equating to 755 miles of roads and 1,490 miles of paths.
This has reduced dangerous potholes by 60% since 2015, placing Sheffield above the national average for the overall highway maintenance indicator in the National Highways and Transport Survey.
In 2019, the project will aim to surface another 100 miles of road and 50 miles of foot ways.
Streets Ahead has been keeping the public appraised of road works through its Twitter account.
