Selected Projects
Modjeski and Masters, has long provided a wide range of bridge engineering services to the railroad industry. We have regularly performed bridge engineering services for each of the Class I railroads in the United States and Canada, for numerous Short Lines and Terminal Companies, and for AMTRAK.
In addition to bridge design, rehabilitation, rating and inspection, and evaluation of bridges through instrumentation and analysis, we offer several special programs and instructional course development.
We have a long history of involvement in the continued development and revision of the American Railway Engineering and Maintenance of Way Association (AREMA) Manual for Railway Engineering.
