He has been the lead design engineer on over 200 projects during his career as a designer for the NHDOT, as a design consultant, and as the engineering manager for a precast concrete company. Tom has spent the last 26 years as an EMT and Firefighter serving his hometown, Henniker, where he lives with his wife and two youngest daughters.
This presentation will provide an overview of the replacement of twin four-span steel deck truss bridges carrying I-91 over the Williams River and Green Mountain Railroad in Rockingham, VT. The new bridges are 860-feet long with piers up to 138 feet tall. Each bridge has five girders comprised of seven segments spliced into continuous girders over 850 feet long. With some individual segments weighing over 93 tons, fabrication, delivery, and erection took careful analysis and planning. To accommodate stringent pier slenderness criteria, rotational stiffness of the piers was increased by incorporating two bearings per girder at each pier. This project is the recipient of the prestigious 2021 PCI Design Award for Bridges with Main Span over 150ft and was selected #6 on the Roads& Bridges top 10 Bridge Projects for 2021.
We feel very fortunate to have Tom join us to discuss this innovative project.
