Weston & Sampson understands the specific needs of public transportation agencies. To assist these clients, we have built a team of skilled professionals experienced in design, permitting, and construction oversight on highway, bridge, transit, complete streets, and bike/pedestrian trail projects along the East Coast.
Our responsive team of project managers, engineers, scientists, planners, stakeholder engagement experts, project controls experts, and construction oversight professionals is prepared to deliver high-quality projects.

These issues include an ongoing need to rehabilitate or replace aging public infrastructure; the determination to adapt to climate change through resiliency enhancements and carbon emissions reduction strategies; the desire to increase alternative travel modes including bicycle, pedestrian, and transit facilities; and a growing emphasis on equity, access, and environmental justice.
