W. Scott McNary, PE

Read Bio
Scott has been designing and helping contractors build bridges since he graduated with a Masters degree from the University of Colorado in 1984. His passion was ignited after attending a lecture by famed Swiss Bridge Engineer Christian Menn in his junior year at CU. He worked for Figg and Muller Engineers for five years after graduation and was lucky enough to learn from Frenchman Gerard Sauvegeot in Denver and Jean Muller himself for 4 months in Paris.

Scott left Figg and Muller in 1989 to start the firm Finley McNary Engineers with Craig Finley. This firm quickly developed a reputation for complex segmental bridges and construction engineering. Notable projects that Scott was responsible for during this time was the Hanging Lake Viaduct in Colorado, The Baldwin Bridge in Connecticut, C & D Canal Bridge in Delaware, the Sidney Lanier Bridge in Georgia and the Natchez Trace Parkway Bridge in Tennessee.

Finley McNary was acquired by Parsons Transportation Group in 2001. During his two years at PTG, Scott was responsible for the Construction Engineering on the Skyway Bridge and the Benicia Martinez Bridge in California.

Scott left PTG in 2003 and formed McNary Bergeron & Associates with Jim Bergeron and Jeremy Johannesen. Notable projects that McB has done under his leadership include the Colorado River Bridge in Nevada, the Maroon Creek Bridge in Colorado, the SW Line Bridge in Tacoma, Washington and numerous footbridges with Bridges to Prosperity.

Scott has been married to his wife Judy for 29 great years. They have three children, Erin, Jack and Tom, who attend the University of Colorado. He enjoys travel, golf, tennis, skiing, woodworking and fly fishing in his spare time.
