The Queensway Tunnel linking Liverpool to Birkenhead is marking its 90th anniversary

Mr Lang said: “It was a real struggle, a real toil trying to get by … so what they achieved was incredible.”

The construction process began in 1925, with 1,700 men working in difficult conditions – manually excavating 1.2 million tons of rock and replacing it with 82,000 tons of cast iron and 270,000 tons of concrete.

Seventeen men lost their lives during construction and are honored annually on Workers’ Memorial Day.

The idea for the tunnel came about after local authorities created a joint committee following lobbying and refusal from the central government.
