A Southampton A-road plagued by works last year has been named one of the most delayed in the country in new data.

Statistics from the Department for Transport lists all of England’s A-roads and their ‘seconds per vehicle per mile’ numbers, which shows how many seconds a vehicle is held up for each mile travelled.

When looking at roads outside of London, Southampton’s A3035 is the fourth most delayed in the country based on 2024 data.

The road – which is part of St Denys Road – has an average seconds per vehicle per mile number of 206.7.

This means that for every mile travelled, the Department for Transport believes drivers had to wait for three minutes and 26 seconds.

The road, which connects Portswood and Cobden Bridge, faced a multitude of issues after a landslip collapsed a wall at the end of 2023.

This caused one lane to be closed for 14 months.

Despite promises to make repairs over the summer, no work started until October 2024, with the road finally reopening after further delays on December 13.

Councillor Eamonn Keogh said that travel on the A3035 last year was “significantly impacted” by the landslip that “undermined the stability of part of the railway bridge” on St Denys Road.

The ward member for Peartree continued: “This closed one lane of the A3035 while legal and safe access to the area was established to enable works by Southampton City Council, Network Rail and Scottish and Southern Electricity Networks to stabilise the embankment, relocate utilities and make repairs to the bridge.

“These works concluded and the A3035 fully reopened in December 2024 and we expect next year’s figures to show that travel times on the A3035 are back to normal.”

The next slowest road to wholly fall under Southampton City Council’s jurisdiction was the A3024, which connects to Maybray King Way to the Windhover Roundabout.

The A3024’s average seconds per vehicle per mile number was 123, meaning drivers were delayed for two minutes and three seconds for every mile they travelled.
