An assessment of the potential effect of construction traffic, including Heavy Goods Vehicles (HGVs), on the local road network was undertaken as part of the Development Consent Order application for the Lower Thames Crossing. This is set out in Chapter 8 of the project's Transport Assessment.

To mitigate impacts on local roads, an offline haul road network is being implemented to reduce the level of construction traffic. Construction traffic is managed through a suite of control documents, and detailed plans for the works underway have been signed off by the Secretary of State following consultation with relevant stakeholders, including Thurrock Council.

The Department has not conducted any research into using connected vehicle technology in this situation.

National Highways has assessed the potential impacts of the Lower Thames Crossing on the road network during construction, including on local roads in South Basildon and East Thurrock. The assessment is set out in Chapter 8 of the Transport Assessment and the Community Impacts Report.

Construction impacts are managed through a suite of control documents, including the Framework Construction Travel Plan and the Outline Traffic Management Plan for Construction. Furthermore, the Wider Network Impacts Management and Monitoring Plan sets out the approach to monitoring traffic impacts on the road network. This monitoring will be undertaken within the year before the opening of the Crossing, a year after opening, and five years after opening, with data provided to the relevant highway authorities.

The Lower Thames Crossing’s Development Consent Order includes a legally binding Outline Traffic Management Plan. This requires delivery partners to conduct joint inspections of access and diversion routes with the relevant local highway authority before works commence, to ensure their condition is suitable for the anticipated use during construction.

Local highway authorities have powers to recover costs for extraordinary damage to highways. The project aims to minimise such cases through measures including the use of offline haul roads and the strategic road network where practicable. Any issues are addressed on a case-by-case basis, considering the initial condition of the road and the level of affect attributable to the project.

Government is aware of the importance of efficient road and rail connections to enable ports to be effective gateways for trade and handle increasing volumes of freight. The Government is delivering major projects to provide a step change in port connectivity, with the Lower Thames Crossing in the South and Trans Pennine Route Upgrade in the North. In March 2026, the Government announced over £27 billion of investment in the Strategic Road Network through the third Road Investment Strategy, which includes a new performance metric for National Highways to reduce delays on gateway routes. In addition, Great British Railways will work to improve rail access with an overall target of a 75% increase in rail freight moved by 2050.

The Government is aware of capacity constraints on the transport infrastructure connecting ports in the Thames region and is working to improve them. This includes delivering the Lower Thames Crossing, the most significant road building project in a generation. The new crossing will reduce congestion at Dartford, better linking up motorists and businesses in the Midlands and North with key ports in the South East, and spreading growth throughout the regions. In addition, Network Rail is delivering feasibility studies on level crossing mitigations at East Tilbury, Rainham, and Grays, as well as progressing a business case development on cross-London lines, recognising the existing capacity challenges in the region.

The Government recognises the impact of historic underinvestment in England’s local road network and is providing a record £7.3 billion over this Parliament to help local highway authorities plan ahead, adopt more preventative maintenance and improve the long-term condition their roads. Local highway authorities are responsible for maintaining their networks and are best placed to decide how to use available funding for their areas.

We have also introduced a new incentive funding system for local highway authorities, with a portion of their funding dependent on them demonstrating compliance with best practice in highways maintenance, and an annual ratings system which grades authorities based on information about the condition of their roads, how effectively they spend their record Government funding, and whether they do so using best practice. Together, these measures will help ensure the increased and long-term investment translates into real improvements for road users.

We are already seeing signs of progress, with the percentage of local roads receiving maintenance treatment in 2025 increasing by 23% for major roads compared to 2024, and increasing by 16% for minor roads.

The Department publishes statistics on the condition of local roads in England annually Road conditions - GOV.UK. In the financial year ending March 2025, in Essex, maintenance should have been considered on 3% of local A road and motorway, 3% of B and C road and 10% of unclassified road. Across England as a whole, for the same period, maintenance should have been considered on 5% of local A road and motorway, 7% of B and C road and 17% of unclassified road.

Local highway authorities are required to publish their Local Highways Maintenance Transparency Reports on their websites by 10 September 2026.

The Department will use the information and supporting evidence provided in these reports to inform its assessment of local highway authorities’ maintenance activity. This will support decisions on eligibility for highways maintenance incentive funding for 2026‑27, with payments made later in the financial year in line with the published funding framework.

The Department will also use this information to update the annual road maintenance performance ratings for local highway authorities, which were first published in January 2026.

The Department’s updated guidance strengthens transparency and accountability in how local highway authorities maintain their road networks. All highway authorities will have to publish reports on how they maintain their network, including how many potholes they fill, whether they do so using long-lasting repair methods, and what action they are taking to prevent potholes from forming in the first place.

This increased transparency is designed to encourage better decision‑making, driving a shift from short‑term, reactive repairs towards more effective, long‑term maintenance approaches, including a greater adoption of long-lasting repairs and preventative maintenance to prevent potholes from forming in the first place.

The information provided will also be used by the Department to inform performance ratings and decisions on highways maintenance incentive funding, supporting continuous improvement across the sector and better outcomes for road users.

Data on road injury collisions in Great Britain is reported by the police via a system known as STATS19. Reporting officers can assign up to 6 factors which in their opinion may have contributed to the collision occurring, including where ‘driver or rider had uncorrected or defective eyesight’.

The number of collisions in Great Britain with the factor ‘driver or rider had uncorrected or defective eyesight’ assigned in each of the last 5 years for which figures are available are shown in the table below.

The third Road Investment Strategy 3 (RIS3) sets the level of performance and investment the Government expects to see in England’s motorway and trunk road network over the period from April 2026 to March 2031. It takes account of evidence gathered over many years from a wide range of sources and stakeholders, and follows a 2023 public consultation. It will benefit all parts of England, including Essex.

DfT Ministers have received correspondence, including from Essex County Council, on the case for the A12 (Chelmsford to A120) widening scheme and on the merits of improvements to the A120 between Braintree and Marks Tey.

In finalising RIS3 investment decisions, Ministers considered a wide range of factors, including alignment with government missions; regional equity; impacts on growth, safety and the environment; and the impacts of congestion on all road users, including freight movements, in different parts of the country. This helped ensure that investment is prioritised where pressures on the network are greatest and where improvements can deliver the most benefit. National Highways will set out further details of how RIS3 funding will be allocated in its Delivery Plan, due in early summer.

National Highways engages with local authorities and other stakeholders as it develops its Route Strategies, which assess the current performance and future needs of the Strategic Road Network and inform future investment decisions. RIS3 was informed by Route Strategies undertaken in Road Period 2 (2020-2025). National Highways will shortly be commencing this process afresh to inform the development of the fourth Road Investment Strategy (RIS4).

The potential impacts of the Lower Thames Crossing on other roads in Essex and elsewhere were appraised through the Lower Thames Area Model, a strategic transport model providing detailed representation of the networks in Dartford, Thurrock, Kent, Essex and East London. This ensured that the project’s expected effects on Thurrock’s road network were properly assessed as part of the wider decision‑making process.

Funding under the Road Investment Strategy is allocated to National Highways for investment in the Strategic Roads Network across England rather than by region or by local highway authority area. It is not therefore possible to give a precise breakdown by county of where the funding will be spent. This will depend on asset need, and operational and other spend.

The condition of local roads in Basildon and Thurrock is the responsibility of the respective local highway authorities. The Government has announced a record investment of £7.3 billion for local highway maintenance over the next four years. Essex County Council is eligible to receive £230,943,000 of this and Thurrock £19,416,000. Decisions on the allocation of this funding are matters for the local highway authority.
