Who Owns Dartford Crossing?

The Dartford Crossing is owned by the public. It belongs to the government, through the Department for Transport, and is managed by National Highways — a company wholly owned by the Secretary of State. The Dart Charge is not a private toll: it is a statutory road user charge, collected under contract, with the money going to government rather than to an operator. Ownership verified 6 September 2026.

Who owns Dartford Crossing today?

The crossing comprises the Queen Elizabeth II Bridge, carrying southbound traffic since 1991, and two northbound tunnels opened in 1963 and 1980. All of it is publicly owned.

It is managed by National Highways, formerly Highways England and before that the Highways Agency — a government-owned company responsible for England’s strategic road network on behalf of the Department for Transport.

Private companies are involved, and this is where the confusion starts. Connect Plus operates and maintains parts of the network under contract, and the Dart Charge collection service is run by a contractor. Neither owns the crossing. A contractor operating an asset is not its owner — the distinction this site draws between brand owners and operators, applied to infrastructure.

Ultimate parent and corporate structure

National Highways Limited is a company registered at Companies House whose shares are held by the Secretary of State for Transport. So the chain is unusually short: the crossing, National Highways, the Secretary of State, and the Crown.

That structure — a government-owned company rather than a department — is deliberate. It gives the road network commercial-style management and accounting while leaving ownership with the state. Network Rail is organised on comparable lines.

Above the Secretary of State there is no parent, no shareholder and nothing to buy.

Major shareholders or controlling persons

There are none. The public interest is held by ministers accountable to Parliament rather than by shareholders.

The most common misconception is that the crossing was privatised. It was not. It was once privately financed, and that arrangement ended. The Dartford River Crossing was built under a design-build-finance-operate concession in the late 1980s, with the operator recovering costs from tolls. Once the debt was repaid the crossing reverted to public ownership in 2002.

Official records and evidence

Companies House holds National Highways Limited and the various contractor companies, and it will show you who owns them — but the crossing itself is not a company and has no entry.

The authoritative sources are the Department for Transport and National Highways, and the statutory instruments that impose the charge. The National Audit Office has examined the crossing’s finances and the Dart Charge contract, and those reports are public.

The charging arrangements themselves are set out in legislation, which is the clearest evidence that this is a road user charge rather than a commercial toll.

Ownership history and changes

• 1963 — first tunnel opens, funded by the government and local authorities, with tolls to repay construction.
• 1980 — second tunnel opens.
• 1988 — the crossing is transferred to a private concession to finance the new bridge.
• 1991 — the QEII Bridge opens.
• 2002 — the concession ends early, the debt having been repaid, and the crossing returns to public ownership.
• 2003 onwards — charging continues, but as a congestion-management charge rather than to repay construction.
• 2014 — barriers removed and free-flow Dart Charge introduced.

The 2002 reversion is the fact that settles most arguments about the crossing: the charge outlived the debt it was created to repay, and continues under a different legal justification.

Related companies and brands

National Highways manages England’s motorways and major A roads, including the M25 of which the crossing forms part. It has no connection to Transport for London, which runs the Blackwall and Silvertown tunnels under different arrangements, or to the separately owned Mersey and Tyne crossings.

The Lower Thames Crossing, the planned new route east of Dartford, is a National Highways scheme and would likewise be publicly owned, whatever financing arrangements are used to build it.
