California Class I Railroad Bridge Design
TWM’s railroad bridge engineering design services were provided for a confidential California Class I railroad with two bridges in need of replacement in 2017. Leveraging the experience of our Structural Engineering Department, TWM’s multi-faceted structural team joined forces with our Railway Department to create innovative, durable, and cost-effective designs for the two bridges. These structures had aging timber supports, and their replacement was part of the railroad’s regular, ongoing maintenance schedule. TWM’s engineering designs included necessary seismic specifications for the region, and the bridges were completed three weeks ahead of schedule.
