Because of problems with deteriorating concrete bridges, civil engineers in Cambridgeshire County, England, looked for alternatives. They rediscovered an old material used to build bridges--brick. Borrowing modern technology that England is now using to build brick buildings, they designed and built the bridge abutments of post-tensioned brick. The bridge abutments were built as a series of cells. Vertical galvanized steel rods were installed in the cells, which were left open. The bars were stressed to 1,000 kilonewtons (224,800 pounds).
