Big milestone reached on Bridge Street on Friday 3 July.

They're big, they're heavy, and they're now in place beneath Bridge Street.

These might just look like big concrete boxes, but they're an important part of the street's new stormwater network.

These underground chambers capture sediment and debris before stormwater moves through the network, improving performance and helping protect the environment.

Once installed, they're hidden beneath the street, working quietly whenever it rains.
