A light hearted look from a nearby resident (and perhaps not quite accurate) As of today they have completed removing ballast, and so the site compound to the east is deserted and no bright lighting towers (fireworks according to Austin - aged 2) are illuminated. They are chipping, grinding, cleaning, wire wheeling, preparing, scraping, blasting, cutting, rubbing, abrading and repairing the steel substructure of the viaduct (I presume). They also have catering, the lucky burgers!
