Tunnels? Out from St Johns Wood

[birdcage]

I used to be able to go for a nice blat to the Hatfield tunnel from where I live in St Johns Wood but it is on specs for a while I think, does anyone know of any other tunnels nearby?

Thanks

there's the one at the maida vale entrance to the A40 going west which is always a bit of fun,

Drive a bit further north on the A1 come off at the A505 (Baldock Bypass) towards Royston etc. After a couple of miles you'll reach a tunnel through a hill.
