And we do a lot of complex bridges . . . so we developed a pretty sophisticated geometric program that can calculate just about anything in space.

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.

The design and construction of the 560-ft bridge taking Fifth Street over I-25 and Plum Creek in Castle Rock, Colo., came up against severe environmental constraints. Plum Creek is the habitat of the Preble's Meadow Jumping Mouse, which is a threatened species protected since 1998 by the Endangered Species Act. Among other things, this act makes it unlawful to significantly modify the habitat in a way that would disrupt normal behavior patterns of the mouse.

Joining forces with the Virginia DOT and Archer-Western Contractors Ltd., Fort Lauderdale, Fla., Parsons Bridge and Tunnel Division developed constructibility modifications for the project. For Parsons, the key to making the process work better was match-casting.
