Philips Road culvert works are now in their sixth week. I presume the civil engineers knew how much concrete was covering the Blakewater culvert before the renewal works were planned but I am surprised by the mass of concrete that has had to be broken up. Last week I reported the jack hammer had been brought in and this week it has been thundering away all week through tons of reinforced concrete that was on top of the covering of the culvert. It looked more like a nuclear shelter at one stage. I can't imagine there was any likelihood of it collapsing. At the downstream end the covering was exposed and has been removed. Further upstream only the covering has been exposed.
