LEDS along the A4 – Reading to Twyford

Wokingham Council have replaced the Sodiums (but left a few high P ones) between Reading and where I live. I am above the lights and see the down-lighting. Its very effective, and I assume many lamps in the Wokingham area (about 5 miles away) are also upgraded. I have not seen any further deterioration in light pollution due to LED lights at my location.  Im on the dark end of Bortle-5  (SQM 20.3).  I continue to use LPR filters for wide angle imaging and I dont think this will ever change.  Given what has been said here, close proximity of these lights and their shear brightness is a serious problem for astronomy.
