Figures from the Department for Transport showing travel times on A-roads around the country have revealed which roads in the county cause the longest delays for drivers.
Of the six A-roads included in the study in Sutton, five had travel times that were significantly longer than average in the year ending December 2024.
The slowest road to drive on was named the A24 in Sutton, which enters the North Cheam area and passes through Sutton Common.
The congestion spot takes road users an average of 182.2 seconds per mile to navigate.
This has increased by 35.9 seconds since 2023, when the average was 146.3 seconds per mile.
The A2043, which runs through Malden Road and Worcester Park, was the second slowest road.
The average time was 145.5 seconds per mile, 10 seconds longer than the average in 2023.
Taking the third spot was the A232 Road, which links Sutton with Croydon.
The road delayed drivers by 121 seconds per mile last year, 12 seconds longer than the year before at 102.3 seconds.
The average delay time in the Greater London Authority is 59.6 seconds.
Only one road in Sutton was below that average time – the A2022 that runs through Bromley, Croydon, Banstead, and Epsom.
The delay time was 29.2 seconds, 30 seconds less than the average time.

The government statistics are derived from weighted speed observations of a sample of vehicles, categorised based on traffic flow patterns.
They reflect traffic volumes across various locations and times of day.
The travel time calculations encompass the entire 24-hour period, including overnight hours, weekends, and bank holidays.
