Annual vehicle usage had exceeded 11 million. Peak-hour queues stretched for miles up the approaches in both Birkenhead and Liverpool, and the tolls were so low that there was no way to throttle demand. Something had to give. After years of arguing about bridges, second tunnels, and even an underwater tube, the conclusion was the simplest one: build another tunnel, this time between Liverpool and Wallasey, and pay for it by raising the tolls. The result, the Kingsway Tunnel, opened on 24 June 1971 under the hands of Queen Elizabeth II, with the name commemorating the king's road that had once led to the same crossing.

Kingsway Tunnel: Why a Tunnel and Not a Bridge

Mon, 25 May 2026 00:00:00 GMT

Photo credit Rodhullandemu, CC BY-SA 4.0. The choice of a tunnel over a bridge had been argued for years. Bridge schemes were attractive in principle: cheaper to maintain, easier to walk and cycle across, less claustrophobic. But the Mersey at the proposed crossing point is busy with commercial shipping that needs full c...
