A hospital manager has raised concerns about the impact the Paramount entertainment resort could have on local health services after developers launched the latest round of public exhibitions.

More than 1,700 people came through the doors in the first three days of the third consultation on the £2 billion attraction due to open on the Swanscombe Peninsula in 2020.

Paul Seymour, maternity manager at Darent Valley Hospital, praised the scheme, which is set to create 27,000 jobs, but said staff did not want to see “ambulances stuck on the hard shoulder” in the event of traffic problems around the resort.

“When they built Bluewater we remember the impact that had on us at Christmas,” he said on the opening day of the consultation at the Old Town Hall, Gravesend, last Wednesday.

“You heard stories of ambulances being stuck on the hard shoulder so we think there should be more consideration.

“They are openly saying they are going to attract young families. I work in maternity so I’m worried there is going to be an impact.

“There has been a lot of negative media coverage about A&E capacity so with all that you would think there would be more consideration for that aspect too.”

Developers revealed a scale model of their plans for the park, named London Paramount, as well as proposals to build a dedicated access road from the A2 to the resort adjacent to the HS1 line.

The park will be opening at 10.30am, perhaps from 11am during winter, avoiding the morning rush hour, when most people will be heading into London rather than out of it anyway.

David Testa, director at London Resort Company Holdings, the developers of the attraction, said: “The one concern everyone has got is about traffic. It is a busy area and Bluewater is extremely busy and clogs up the arteries at certain times.

“We have got good ideas about how we can mitigate that. The key one is about expenditure to upgrade the Ebbsfleet junction and to build a mile-long dedicated access route which will not mix with local traffic.

“The other reason we chose this site is because of the rail connectivity. We have Ebbsfleet International but Swanscombe station too, where we could easily get several thousand people coming in each year.

“There is also the river, which will offer low figures in terms of percentage, but still bring in 300,000 to 400,000 people per annum.

“During construction we can get 80% of our construction materials from the river which is a big mitigant during that phase.”

While traffic remained a major concern, most visitors to the exhibition want the project to happen.
