  • Ongoing

The project, which will provide faster and more reliable transit service, is being delivered under a public-private partnership (P3).

We worked closely with the owner and the project’s numerous stakeholders to bring this project from vision to completion in a manner that will provide lasting benefits to the region. WSP provided support throughout the P3 solicitation process and document preparation, including technical provisions and performance requirements. Services included planning, engineering, ridership forecasting, environmental impact analysis and documentation, and cost estimating. We also assisted with documentation requirements to obtain a $900 million federal capital grant.
