I went down this tunnel once, the escalators were out of action unfortunately, so a big lift was used instead. It's surprising how spacious it is down there, and ideal for biking down the tunnel.
There's a sign in the tunnel that says something like "cyclists are tolerated, but only at walking speed". I frequently get into arguments wich douchebags who ignore this rule and ring their bells like antisocial nutcases at pedestrians in the tunnel. You know, the way drivers do when cyclists aren't moving fast enough for their tastes.
Anyway there is a real problem here with the river crossings, I am always astonished how few options there are and how all of them are either unreliable, congested or slow.
There's a sign in Denmark, the standard bicycle+pedestrian plus the text "Knallert forbudt"[1], often seen where the path is shared with pedestrians — like on a quay or in a park.
I'd assumed "knallert" was cognate with English "knell", meaning to ring (or the sound of) a bell, and the sign therefore meant a cyclist mustn't ask people to move out of the way. But it seems that "knell" in Danish is "knolde"[2], and the sign is the much simpler "Mopeds forbidden".
I like my meaning better.

On a warm summer’s day it’s nice to get out of the stuffy city using this tunnel. It’s always cool down there, and the monotony of the walk relaxes the mind. On the other shore there’s lots of green and open space, very quiet.
