Why yes, I am stretching out a single day trip to Liverpool and Wirral into four blog posts. The first was our trip to Eureka Science + Discovery in Wirral, the second about the Mersey ferries, the third about the Museum of Liverpool, and now this, about the tunnels that run under the River Mersey between Liverpool and Wirral.
There are three tunnels under the River Mersey; the oldest is the railway tunnel, which is now part of the Wirral Line of Merseyrail. The Queensway Tunnel opened in the 1930s, and is the oldest road tunnel, with the Kingsway Tunnel opening in the 1970s to relieve congestion. As it happened, Google Maps directed me through the Queensway Tunnel on the way there, and Kingsway Tunnel on the way back. And I got to experience the Mersey Railway tunnel back in 2010, so I’ve now been through all three.
Both road tunnels charge a toll – it’s about £2 for cars, but check the Mersey Tunnels web site for current prices. The toll plazas are on the Wirral side; unlike the newer Mersey Gateway Crossing further upstream, you have to pay to enter or leave the tunnels and can’t pay later online. Thankfully, card payments are accepted as well as cash.
The two tunnels differ in design. Both have two lanes of traffic easy way, but the newer Kingsway Tunnel has two separate bores rather than one single wide bore. The Kingsway Tunnel is also the only one open to heavy goods vehicles; the Queensway Tunnel has a 3.5 tonne weight limit, and buses must use the offside lane due to the lower ceiling. They’re also different lengths; the Queensway Tunnel is about 1 km longer than the Kingsway Tunnel, even though the Kingsway Tunnel is further downstream.
Another interesting fact is that the tunnels have their own police force; indeed, there are four police forces active in Liverpool. As well as the Mersey Tunnels Police and Merseyside Police, Liverpool Cathedral and the Port of Liverpool also have their own police forces. That’ll make a good pub quiz question.
The tunnels need ventilation shafts, and many of these are now landmarks alongside the River Mersey; indeed, the Georges Dock shaft in Liverpool is now grade II listed.
If you don’t want to pay the tolls, then expect to make a much longer journey. The next two crossings upstream, the Silver Jubilee Bridge and Mersey Gateway Crossing, also charge tolls (and the prices are similar), so the first ‘free’ bridge over the River Mersey that you can drive across is in Warrington. When I was planning my journey, a route avoiding the tolls took me down the M6, across on the M56 and up into Wirral on the M53, adding around 7 minutes and 32 km (20 miles) onto my journey. The extra fuel burnt would probably have equated to the toll.
