diestelhorst replacement bridge
MacDonald Architects provided aesthetic design assistance, model building, and renderings for the engineering clients for this new five span arch bridge over the Sacramento River in Redding, California.
The new bridge runs parallel to the historic Diestelhorst Bridge, using a modern architectural vocabulary while retaining the proportions and scale of the existing structure.
The old bridge, which now serves as a pedestrian/bicycle bridge, was the first bridge constructed for automobiles built over the Sacramento River.
Detailed design and coordination with bridge engineers continued through the construction documents, lighting, materials, surfaces, and the roadway and bridge profiles, which were fully developed during this period. The structure spans a public riverfront park and a seasonal salmon breeding ground.
