  • Planning, design, development, and construction
  • Analyzing and resolving traffic impacts
  • Navigating the environmental process
  • Asset management
  • Construction engineering and constructability
  • Technical concepts and modeling
  • Intelligent transportation systems

Crossing New Bounds

We design and build bridges to enrich skylines and provide efficient transportation. With a portfolio of more than 4,500 crossings around the world, we’ve delivered landmark bridges that carry pedestrians, roads, railways, and pipelines. A trailblazer in accelerated bridge design and construction, we are the designer of choice for alternative delivery and disaster recovery projects that reconnect, restore, and rebuild communities when it matters the most. Our proficiency includes the following bridge types:

  • Complex
  • Conventional
  • Long-span
  • Prestressed
  • Post-tensioned
  • Suspension
  • Cable-stayed
  • Segmental
  • Steel
  • Concrete
  • Movable structures

Groundbreaking Innovation

When it comes to transportation infrastructure, we’ve worked on some of the top projects in the world, and our experience shows. No matter the challenge, we have the expertise, the agility, and the flexibility to complete iconic projects and safely get people where they need to go. Our expertise encompasses:

  • Top-down tunneling
  • Advanced hard-rock and soft-ground tunnel-boring machine
  • Single-pass tunnel construction
  • Advanced tunnel waterproofing systems
  • Sequential excavation method/new Austrian tunneling method
  • Horizontal directional drilling
  • Immersed tube
  • Cut-and-cover
  • Microtunneling

Our road, bridge, and tunnel solutions get our customers over, under, around, or through the toughest challenges. With technical and construction capabilities, as well as financial strength, Parsons delivers infrastructure that incorporates sustainability and resiliency to serve the needs of communities for years to come. Capable of acting as a designer, a builder, a developer, or all three, we’re a unique integrated-solutions provider. As experts in alternative project delivery methods, including design-build (DB), public-private partnerships (P3s), and design-build-finance-operate-maintain (DBFOM), we do what it takes to get the job done.
