Road beginning to dip on LL opposite townley rd

[teddyboy23]

I've noticed over the last week the road is beginning to sink in exactly the same spot.where a sink hole appeared last year shutting off LL to transport links for a couple of weeks.the dip is just pass the traffic lights on junction with townley Rd.

Can't be sure, Ted, but reckon there could be an underground stream running down LL. Might be causing the warps. Any local geologists know anything about that?

Thames Water have dug up / resurfaced that section several times now. the issues always seems to come back. 

In terms of rivers - I think the Effra river basin covers some of Lordship Lane, so could be some long covered / redirected tributaries? The culverted Effra itself runs further to the west though https://turneyandburbage.wordpress.com/2015/01/19/ever-wondered-about-the-route-of-the-river-effra/

Found this 'interesting' (all relative of course) map on some of London's covered waterways. If you zoom in, you can see where they run, overlaid with modern street layout: https://www.hiddenhydrology.org/london-barton-the-lost-rivers-of-london/
