• Works are located opposite the junction with Helen Road and have prompted multi-way traffic signals.

• Helen Road is also closed until 7 September near Ardleigh Green Junior School.
• Transport for London (TfL) expects Essex & Suffolk Water to finish water works by end of August, with resurfacing to follow.
• Motorists and bus users face additional travel time of 2–4 minutes on affected routes.

Hornchurch (East London Times) July 23, 2026 –Drivers in Hornchurch are being warned to expect continued delays on Ardleigh Green Road as roadworks are projected to remain in place until early September. According to the roadworks information platform Causeway one.network, the works opposite the junction with Helen Road could last until 4 September 2026. Havering Council, which is overseeing the project, introduced multi-way traffic signals when work began on Tuesday 21 July, with motorists advised that delays are “likely” for the duration.

As reported by the Romford Recorder, the council has maintained that the traffic management measures, including temporary signals, are expected to stay active throughout the roadworks period.

The outlet also noted that Helen Road will be closed until 7 September near the entrance to Ardleigh Green Junior School, compounding disruption for local traffic and school-run commuters.

Who is responsible for the roadworks and traffic management?

Havering Council is the lead authority responsible for the roadworks on Ardleigh Green Road. The council implemented multi-way signals to manage traffic flow when the works commenced on 21 July.

In its guidance, the council directs residents and motorists to consult the Causeway one.network map for confirmed roadworks and closures across the borough, including this site.

Transport for London (TfL) is also involved due to the road’s status within the wider transport network. In a recent update, TfL indicated that Essex & Suffolk Water is expected to complete its water-related works and return the site to TfL by the end of August.

Final resurfacing will then be required before the road network can be fully reopened, according to the Romford Recorder.

Where exactly are the roadworks and what closures are in place?

The works are situated on Ardleigh Green Road opposite its junction with Helen Road in Hornchurch. Alongside the main carriageway works, Helen Road is closed until 7 September near the entrance to Ardleigh Green Junior School.

The combination of lane restrictions on Ardleigh Green Road and the closure on Helen Road has created a pinch point for local traffic, particularly during peak hours.

Causeway one.network lists the event as running from 20 July to 4 September 2026, with continual updates as the works progress. Residents are advised to check the platform for live status changes, as durations can shift depending on utility works and weather conditions.

How will traffic be affected and what delays are expected?

Motorists are being warned that delays are “likely” while the multi-way signals operate. TfL’s traffic status updates indicate that road users on Ardleigh Green Road, Gubbins Lane and Gooshays Drive are experiencing an additional travel time of 2–4 minutes on average. North Street is also seeing 2–3 minute delays in the wider area.

Bus services using the corridor have been affected at times. Recent disruption notices for the 256 bus route show diversions via Slewins Lane, Brentwood Road and Squirrels Heath Lane when incidents or closures occur on Ardleigh Green Road.

While those specific diversions were tied to a road traffic collision earlier in July, the pattern underscores how sensitive the route is to interruptions.

What statements have been issued by authorities and utilities?

Havering Council has not issued a detailed public statement beyond confirming its responsibility for the works and the deployment of temporary traffic signals. Its standard advice is for road users to consult Causeway one.network for confirmed works and closures across Havering.

Transport for London, as cited by the Romford Recorder, has provided the most specific timeline, stating that Essex & Suffolk Water is expected to complete its water works and hand the site back to TfL by the end of August. After that, final resurfacing will be carried out before full reopening.

No direct quote from Essex & Suffolk Water is available in the published reports, but TfL’s update frames the utility’s works as the critical precursor to the final highway reinstatement.

What should drivers and residents do during the roadworks?

Motorists are advised to plan extra time for journeys through Hornchurch, especially during peak commuting hours and school run periods. The Romford Recorder notes that delays are “likely” for the duration of the works, and TfL’s data supports the expectation of added minutes on key local routes.

Residents and regular commuters are encouraged to:

• Check Causeway one.network before travelling for the latest status on Ardleigh Green Road and Helen Road.
• Allow additional journey time of at least 5–10 minutes as a buffer, given reported 2–4 minute average delays.
• Consider alternative routes where feasible, particularly for non-essential trips during peak hours.
• Monitor TfL updates for bus route changes if relying on public transport.

Background to the Ardleigh Green Road development

Roadworks on Ardleigh Green Road form part of routine utility and highway maintenance activity in Havering.

The borough regularly hosts planned works for water, gas, electricity and telecommunications providers, often coordinated through the Street Works regime under the New Roads and Street Works Act 1991.

Havering Council publishes all confirmed roadworks via Causeway one.network, allowing residents and businesses to view planned closures, lane restrictions and expected durations.

The involvement of Essex & Suffolk Water points to underground water network works as a primary driver of the current disruption. Such projects typically require excavation, pipe replacement or repair, followed by reinstatement of the carriageway.

TfL’s role reflects the strategic importance of the route within the wider London road network, where even local works can have knock-on effects for bus reliability and journey times.

Earlier in 2026, Ardleigh Green Road was also listed in a Havering notice for carriageway patching alongside Parkstone Avenue, Butts Green Road and the A127, indicating ongoing maintenance attention on this corridor. The current scheme appears more extensive, given the multi-week duration and the associated closure on Helen Road.

Prediction: How could this development affect local drivers and commuters?

If the roadworks continue as currently projected until early September, local drivers, bus users and school-run families in Hornchurch are likely to face persistent, moderate delays through the summer.

The 2–4 minute average increase on Ardleigh Green Road and adjoining streets may appear modest in isolation, but compounded over multiple journeys and peak periods, it can materially affect punctuality for commuters and increase congestion at nearby junctions.

For bus passengers, the risk of more frequent short-term diversions or bunching remains elevated, particularly if incidents occur on the already constrained corridor.

For businesses relying on timely deliveries or service calls in the RM11 and RM12 postcode areas, the extended timeline may necessitate revised scheduling to accommodate slower traffic flows.

Once Essex & Suffolk Water completes its works and final resurfacing is done, the immediate disruption should ease. However, if utility projects in the area continue in sequence, residents could experience intermittent further works on adjacent streets.

The most significant near-term impact is therefore a sustained period of reduced road capacity and reliability on a key Hornchurch artery, with the greatest effect on those travelling during morning and afternoon peaks.
