Finnoe Design has broad experience designing and fabricating the support structures and personnel access structures required for bridge construction.

While we are sometimes approached with a complete set of design drawings, we often start with only a rough idea of what is needed.  We complete the design, have it engineered, detail it, and fabricate it, usually within a very aggressive time frame.  Knowing the time sensitivity of bridge projects, we make your project a top priority.  Whether you are looking for temporary steel detailing only or detailing with fabrication, we will keep your project on schedule.

See some of our temporary steel bridge projects, including the San Francisco Oakland Bay SAS Bridge.


Finnoe Design has extensive experience detailing bridge retrofits and repairs. Our recent retrofit projects include:

Walt Whitman Bridge

George Washington Bridge

US 190 Bridge

Louisiana, Batton Rouge

Angus MacDonald Bridge in Canada

Tappan Zee in New York

Our typical process includes taking existing shop and contract drawings for the project, sometimes as old as the early 1900s, and redrawing the existing structure to ensure the new replacement pieces fit into the structure as designed.  During the retrofit, we work closely with the field crews to ensure that everything is correct.  We have perfected this process over the last 8 years.
