Millipede Bridges are also available in a CorTen version. Using CorTen posts instead of wood gives this bridge the same organic-inspired look and feel as the standard Millipede Bridge, but with a distinctive twist. The angular-bow shape of the posts perfectly brings out the hues in the CorTen patina. The CorTen posts require little maintenance over the life span of the bridge, making this bridge a good investment in terms of both style and budget. Streetlife delivers its CorTen products unweathered allowing a lovely variety of hues to appear in the first year of use. CorTen turns a deep brown shade over time.
