Bridges

Herrera provides a range of services for bridge projects, from inspections and cumulative impact assessments to design and permitting. Our team designs and permits bridge crossings, culvert replacements, and road realignments with a strong focus on aquatic connectivity, fish passage, and minimization of resource impacts. We support phased environmental review for bridge and road projects, aligning permitting, Endangered Species Act compliance, and National Environmental Policy Act (NEPA) documentation with the evolving engineering design. Our scientists and planners understand practical construction limitations, and along with our engineers, they develop solutions that meet environmental regulations, minimize environmental impact, and succeed within today’s permitting climate.
