The Mersey Tunnels in Liverpool connect the city to Wirral. Two tunnels serve the area, each with a distinct history. The Queensway Tunnel, opened in 1934, links Liverpool city centre to Birkenhead. The Kingsway Tunnel, built later in 1971, connects Wallasey to Liverpool. Both tunnels handle significant traffic. Thousands of vehicles pass through daily. The tunnels remain key routes for commuters and travelers.
