Our nation’s infrastructure evolves rapidly, but we also try to preserve what we can of the past. Restoring old pathways and other structures that have been weathered over the years gives us a unique opportunity to walk in the footsteps of history. When we work to restore historical structures, our goal is to preserve the past.  Research and Planning Whether a pathway winds through the country or the heart of a historic city, they have been a part of the past.

Long-span bridges include a lot of space between their supports, and that allows them to cover wider gaps like deep valleys and very wide rivers. Supports are critical for bridges, so when there isn’t much space to include them, bridge designers and engineers need to spend additional time calculating estimated load and how to includes enough support for the long bridge using minimal space. This advanced structural design, coupled with materials and construction techniques, can help ensure that two distant points are safely connected. Materials and Forms Long-span bridges need materials that can hold up to immense forces, but they […]
