... and still a bit of work going on around 1030. But hardly the sort of intensive activity that one might hope for when a major route is blocked.
Noise inconvenience to local residents is clearly a factor in determining acceptable hours of work, but I would have thought that 6am-10pm might be more appropriate for this sort of job than 8.30am-4.30pm!
Will they be working over the weekend - when traffic is a bit lighter?
