This Cedar Log Bridge is made from cedar logs. This Cedar Log Bridge is naturally resistant to decay and insects so it makes a perfect choice for the lawn and garden accents. The brightness of the wood will turn a silvery gray when it is left outside to weather. We recommend a quality penetrating oil finish to aid in preserving its natural beauty. You may notice some cracks in the log pieces. These cracks are called checks. Checking occurs when the logs dry and cells shrink casing the wood to split. The cedar logs will not only be safe, but checking helps give the cedar bridge the rustic beauty you are looking for SOME ASSEMBLY REQUIRED
