Just come across a “Missing Roundabout” report at https://world.waze.com/editor/?lon=-0.59701&lat=51.50607&zoom=6&layers=BTTFFTTTTTTTFTTTTTTTTTTFT
The issue appears to be that Slough Borough Council have installed a temporary roundabout for the next twelve weeks :http://www.sloughexpress.co.uk/News/All-Areas/Slough/Delays-expected-as-temporary-roundabout-is-put-in-at-busy-town-centre-junction-16042013.htm
So do I change it for twelve weeks or just leave it?
