It is understood that a person was thrown from a vehicle and hit the windscreen of a lorry that was part of the road works.
It is thought the vehicle the victim had been travelling in was a 1903 Knox Runabout Old Porcupine.
The accident comes as many car vans have travelled between London and Brighton for the London to Brighton Veteran Car Run.
Each year car enthusiasts drive their vintage rides – it is considered the most prolific retro car rally in the world.

When it was first released it was capable of hitting a top speed of 35mph through its 8hp two-cylinder engine.
The four-seater vintage rear-wheel drive vehicle was designed by Harry A. Knox – one of the pioneers of the horseless carriage industry – and initially sold for $2,000.
In 2012, one of the surviving models was sold at auction through Bonham’s for $69,000 (around £53,000).
Knox produced approximately 1,000 vehicles in 1904, including two- and four-cylinder cars and trucks.
Traffic from M23 J7 can use the A23 southbound towards Gatwick, and then join the M23 southbound from J9A.
Northbound traffic can either travel anti-clockwise on the M25 to J6, then the A22 northbound to Purley.
The road is expected to remain closed for several hours as investigation works continue.
