Services Bridges and Undercrossings

Highways, rail lines, creeks, and other linear features can pose substantial barriers to connectivity and active travel for many communities. Overcoming these barriers is often technically and financially challenging, and requires strong political support and coordination among multiple agencies and stakeholders.

Alta has helped dozens of communities advance and build non-motorized barrier crossings by providing a unique blend of services that spans all project phases:

  • Demand modeling and network planning ensure that the project is correctly located and sized, and undergoes a rigorous cost/benefit analysis

  • Concept design and environmental assessment that helps produce efficient, constructible alternatives where all costs are identified and risk is minimized

  • Creative public outreach and grant writing that solidify project support and funding

  • Landscape/wayfinding design and engineering services that maximize safety, inspire the user, and respect the environment

Whether we’re supporting or managing a team that can include geotechnical, structural, civil, and architectural specialists, we know how important these projects are for our clients and what it takes to “get it right” on time and under budget.
