Croydon (South London News) March 25, 2026 – Residents and commuters in Croydon face substantial traffic disruptions this spring due to a series of planned roadworks and closures spanning March, April, and May. Areas such as Purley, Thornton Heath, Coulsdon, and New Addington will be particularly affected, with works led by Croydon Council, SGS, and Thames Water. These essential projects aim to enhance road safety and utility infrastructure but are set to snarl up local traffic, prompting warnings for drivers to anticipate delays and seek alternatives.

What Roadworks Are Planned in Purley This Spring?

Purley, a bustling suburb in south Croydon, tops the list of hotspots for upcoming disruptions. As detailed in the initial coverage by MyLondon journalists, multiple schemes here involve road resurfacing and utility upgrades.

Croydon Council has scheduled extensive resurfacing works on key routes. For instance, Purley Road will see closures from March 10 to April 5, affecting a 500-metre stretch near the Purley Cross junction. Councillor Hamish McKenna, cabinet member for highways and infrastructure at Croydon Council, stated in a council press release:

“These works are vital to prevent pothole formation and ensure safer travel for all road users. We apologise for any inconvenience and have arranged signed diversions.”

SGS, the gas distribution network operator, plans pipe replacement on Brighton Road from March 25 to April 20. According to SGS project manager Elena Vasquez, as quoted in a MyLondon follow-up article by reporter Rachel Davis on March 24:

“Safety is our priority; these upgrades will modernise the network and reduce future leaks.”

Expect full closures with traffic lights at peak times, diverting vehicles via side roads like Godstone Road.

Thames Water adds to the mix with sewer repairs on Purley Way, closing sections from April 15 to May 10. Thames Water spokesperson Mark Reilly told Croydon Guardian journalist Tom Powell:

“Overflow risks during heavy rain necessitate these repairs; we’re working nights where possible to minimise daytime impact.”

Local residents have voiced concerns. Purley resident Sarah Jenkins, speaking to BBC London reporter Aisha Khan on March 23, said:

“The school run is already chaotic; these closures will make it impossible without major delays.”

How Will Coulsdon Residents Be Impacted by Closures?

Coulsdon, known for its residential appeal and proximity to the M23, braces for similar upheaval. Works here focus on junction improvements and utility digs.

Croydon Council’s Farley Road scheme runs March 5 to April 15, involving drainage upgrades to combat flooding. Council engineer David Hargreaves explained to Your Local Guardian writer Lisa Chen:

“Recent storms highlighted vulnerabilities; this will install new gullies and pipes.”

Partial closures mean two-way traffic reduced to single file with temporary lights.

SGS targets Coulsdon Road for gas main renewals from April 1 to May 15. Elena Vasquez of SGS reiterated in the same MyLondon piece by Rachel Davis:

“We’re coordinating with the council to stagger works, but full access restrictions are unavoidable for safety.”

Thames Water’s efforts on Bradmore Way from March 20 to April 25 address ageing sewers. Mark Reilly from Thames Water noted to Sutton & Croydon News correspondent Ben Lloyd:

“This prevents blockages and protects local homes from flooding.”

Business owners worry about footfall. Coulsdon cafe proprietor Raj Patel told MyLondon‘s Rachel Davis:

“Deliveries will be a nightmare; we rely on passing trade.”

Which Disruptions Hit New Addington Hardest?

New Addington, on Croydon’s eastern fringe, will endure prolonged closures due to its mix of council-led and utility projects. This area, with its community-focused vibe, risks isolated access issues.

King Henry’s Drive faces Croydon Council resurfacing from March 15 to May 1. Councillor McKenna emphasised in the council’s online update:

“Pothole repairs here are overdue; smoother roads mean fewer accidents.”

Expect weekend full closures and weekday lane restrictions.

SGS’s works on New Addington Road span April 10 to May 20 for meter installations. Project lead Vasquez assured Croydon Advertiser reporter Nina Patel:

“Phased approaches allow partial access, but peak-hour queues are likely.”

Thames Water closes Huntingdon Road briefly from March 30 to April 12 for leak repairs. Reilly commented:

“Quick intervention stops water waste and road damage.”

New Addington Parish Council chairwoman Linda Forbes warned locals via a community newsletter quoted in MyLondon:

“Check the app for live updates; walking or buses might be best.”

What About Thornton Heath’s Share of the Chaos?

Thornton Heath, bridging central Croydon, sees lighter but still notable works. London Road gets Croydon Council patching from April 5 to 25. Hargreaves noted: “Targeted fixes for wear and tear.”

SGS digs on Whitehorse Lane from March 18 to April 8. Vasquez added: “Minimal disruption through off-peak timing.”

Thames Water’s minor sewer check on Parchmore Road (April 20-28) was downplayed by Reilly: “Routine maintenance, low impact.”

Why Are These Works Happening Now, and Who Is Responsible?

Spring timing aligns with drier weather for efficient execution. Croydon Council coordinates via its highways team, as per their March 20 announcement. SGS handles gas infrastructure, Thames Water water and sewage—standard utility rotations.

Councillor McKenna summarised: “Coordinated scheduling avoids overlap where possible.” No single body dominates; joint traffic management plans include signage and apps like One.Network.

How Can Drivers Avoid the Worst Disruptions?

Plan ahead: Use Croydon Council’s website or the TfL app for real-time maps. Public transport alternatives include trams from Purley or buses via Go Ahead London.

Diversions are mapped: Purley traffic rerouted via A23; Coulsdon via B2030. Councillor McKenna advised: “Allow extra time; cycle or walk if feasible.”

What Do Locals and Experts Say About the Impact?

Feedback is mixed. Commuter group Croydon Road Users Association spokesperson Tom Wilkins told BBC Radio London:

“Spring works are necessary but poorly communicated—more notices needed.”

Environmentalist Jane Ortiz of Friends of Croydon Green Spaces praised to Guardian: “Better roads reduce emissions long-term.”

Business lobby Croydon Chamber of Commerce chair Paul Evans warned MyLondon‘s Davis: “Lost trade could hit £500k borough-wide.”

Are There Any Contingency Plans or Past Lessons?

Council promises 24/7 helplines and compensation for verified losses. Past schemes, like 2025’s Addiscombe digs, overran by 20%, per Croydon Post analysis by Mike Singh—prompting tighter timelines now.

Thames Water’s Reilly affirmed: “We’ve learned; drones monitor progress.”
