Bridges and Highways

RETTEW has provided comprehensive bridge, highway and traffic services for more than 40 years, regularly addressing all aspects of roadway geometry, bridge condition, traffic operations and signalization for the efficient flow of traffic as well as the safety of pedestrians and the motoring public. Our excellent working relationship with state DOTs and DEPs as well as FHWA has enabled us to move transportation projects forward with exceptional speed and efficiency. In-depth knowledge of state and local regulations and procedures help us stay ahead of any issues as we facilitate applications, designs, plans, specifications and studies for our clients.

RETTEW’s designers and engineers are experts at context-sensitive designs that consciously balance safety, mobility and transportation needs with preserving scenic, aesthetic, historic, environmental, cultural and community assets. We have designed or rehabilitated hundreds of bridges and highways for PennDOT, the Pennsylvania Turnpike Commission, county and local governments, and contractors and fabricators. Our work has been recognized by several professional organizations including the American Society of Highway Engineers (ASHE) and the Association for Bridge Construction and Design (ABCD).
