THE Queensway tunnel is to open for the public to walk though on its 75th anniversary – for what could be the last time.

Merseytravel said it will be many years before they repeat Sunday’s “Under and Over the Mersey” event.

On Wednesday, July 18, 1934, more than 200,000 people gathered at the Old Haymarket in Liverpool city centre to watch King George V and Queen Mary officially open the Queensway Tunnel.

Before it opened, almost 80,000 took the chance to walk through the tunnel, paying 6d each – all of which went to charity.

Around 20,000 people are expected to celebrate the anniversary this Sunday, by walking through it – and again raise money for charity .

Funds will go to Claire House children’s hospice in Wirral, Merseyside.

The event will be hosted by Keith Chegwin and includes a full programme of entertainment for all the family, as well as a trip back over the river on the Mersey Ferries.

Single tickets are £5 and family tickets ( two adults two children ) are £15.

Walks take place at 10.30am, 11.15am, 12 noon, 12.45pm or 1.30pm.
