Glued-together beauty   Roads & Bridges December 2003
Today, timber bridges are enjoying a resurgence because they offer special benefits to designers and owners. They are considered environmentally friendly because timber is our only renewable resource. In addition, the increased strength of today’s modern glued laminated timbers helps to achieve longer spans and carry heavier loads than conventional timber bridges in the past.

Star treatment for a mouse   Roads & Bridges November 2003
