More Than 130 Years of Innovative Engineering and Durable Designs for Rail and Transit Clients

The rail market has been an important cornerstone of our business since the completion of our very first project in 1890. To this day, we continue to add to our impressive record of performance and provide rail clients with innovative engineering and durable designs for rail bridges carrying passengers and freight throughout North America.

We offer expertise in all disciplines pertaining to rail bridges, including structural, electrical, mechanical, and geotechnical; and in all phases of work, from planning and inspection/investigations through design and construction phase services. We also offer services such as value engineering, constructability review, forensic analysis, and asset management to our transit clients.

H&H is committed to and actively participates in the development and advancement of industry standards, through leadership in such organizations as the American Railway and Maintenance-of-Way Association (AREMA).
