Keller Group
Transportation infrastructure must perform reliably under constant use and complex conditions. Keller partners with transportation agencies, authorities, and contractors to deliver geotechnical solutions for new construction, expansion, rehabilitation, and emergency response while managing risk and minimizing disruption to active operations.
Geotechnical construction solutions for transportation projects
Keller provides a full range of geotechnical construction solutions for transportation projects using an integrated design-build approach focused on constructability, safety, and service continuity.
Our work supports roadways, runways, rail transit corridors, bridges, tunnels, and terminals through ground improvement, foundation support, earth retention, slope stabilization, and groundwater control. Keller matches solutions to project requirements to reduce construction cost and schedule risk while protecting critical transportation assets.
When urgent conditions arise, including slope failures, sinkholes, or infrastructure distress, Keller responds quickly and efficiently to restore safe operations and limit downtime.
Keller’s experience in transportation infrastructure
Keller has delivered transportation projects for local, state, and federal agencies across North America, supporting some of the most heavily traveled and operationally sensitive infrastructure systems.
Our experience working within active transportation corridors enables us to plan work carefully, manage risk, and maintain safety and quality while construction proceeds adjacent to live traffic and operations. This experience allows Keller to help owners extend service life, improve resilience, and maintain confidence in critical transportation networks.
Sector challenges we can solve
- Protecting transportation infrastructure from settlement and distress
- Supporting widening projects and corridor expansions
- Ground improvement and foundation support for new construction
- Emergency response to slope failures, sinkholes, and infrastructure damage
- Maintaining operations during construction in active corridors
