Built in the 1930's, the Mersey Tunnel was, and is still considered a masterpiece of civil engineering, but how was it built?

It twists and turns throughout it's length, and even has inclines and declines, unlike many rail tunnels which are dead straight,... how did they know where it was going to emerge?...They could not even be guided by vertical ventilation shafts, as in the Woodhead and Stanedge pennine rail tunnels, because of the million of tons of water above it.

They just marked a tunnel shape out on the wall and surrounded it with security fencing. Scousers did the rest.

A bit off topic but the day I bought my Corrado VR6 from Birkenhead I drove back through the Mersey Tunnel followed by my friend in his Polo G40, they both sounded amazing in there!!

Yep

Kingsway being the newer of the two that is at the end/start of the M53

Queensway is the older twisty one and apparently follows some of the road layout above (or at least that what I was told as a kid)

They both go up and down, otherwise after a few hundred yards, you'd be in rather than underneath the Mersey hehe

Various Ferraris TVR's & Porsches, have sounded fantastic being driven through at a steady 40mph wink with my RUF 964 belching flame and sounding like a LeMans car, with the roof down late at night being a rather addictive experience.
It was supposed to be free once the costs were paid off, however that still hasn’t happened and the operators filling their pockets in a one for you one for me scam didn’t help that! . . . . . . but at £1.25 each way, its not too much and the fast tags at least mean that I’m no longer searching for change
