The railway bridge is under attack

This just came up on Twitter - what do lorries have against that poor railway bridge?!<br><br>http://www.hamhighbroadway.co.uk/news/tesco_lorry_hits_finsbury_park_bridge_and_tips_over_1_2940789<br>;

how the heck did he manage this?<br><br>Thank goodness no-one way under the bus.<br><br>I'm wondering whether it would be cheaper just to lower the road and allow lorries.<br>

It was a Tesco lorry.  That should make the milk shake then.<br>

Just came home an hour ago and saw what happened, thinking how did he manage *that*?<br>

Did anyone see it happen? I'm intrigued by the physics of it. Surely it most have been going at some speed to completely turn over and end up on the pavement on the other side of the road!

A giant threw it under the bridge.<br>

It gets better:  I've just seen them finally right the tailer, and on the side is "You shop, we drop"

@Yagamuffin: Not really - It hit a rigid sacrificial beam on the front of the bridge that is going nowhere. Momentum is going to be conserved and the kinetic energy is going to go somewhere.    Some of it goes in mashing up the front end of the trailer (I think the tractor just got under, as last time). My guess is the road - as all roads, has a camber, and the corner towards the centre hit first twisting the trailer.  The tractor would then have jack-knifed with it. <div><br></div>

@Marko That makes sense, I forgot until I saw it this morning that the bridge is at an angle across the road.

Stroud Green Road is closed today whilst steelwork to support a bridge protection beam is installed at the bus station end of the railway bridge.  It will later receive a 32t, concrete filled, steel pipe on the top of it.<div><br></div><div>Apparently the other side of the bridge - which is where lorries involved in the recent strikes have come from - is getting one too. </div><div><br></div><div><br></div>
