Triangle Bikeway Study

This 17-mile corridor paralleling I-40 crosses three counties, connecting Raleigh, Research Triangle Park, Durham and Chapel Hill, North Carolina. McAdams led the study, which included a standing working group of stakeholders; community outreach along the entire corridor; coordination with both Capital Area Metropolitan Planning Organization (CAMPO) and Durham-Chapel Hill-Carrboro Metropolitan Planning Organization (DCHC MPO); and one-on-one coordination with key stakeholders, including State Parks, Raleigh-Durham International Airport, SAS Institute and Duke Energy.

This project developed alternatives that included both improvements to existing bike lanes and sidewalks; and dedicated facilities on structures and at-grade.

The final project included detailed cost estimates; video simulations; technical recommendations; and cost benefit analysis suitable for pursuing Rebuilding American Infrastructure with Sustainability and Equity (RAISE) or other Federal grants. During the pandemic, the McAdams team reached over 2,000 citizens and connected with seven jurisdictions through a variety of virtual means, including a dynamic website.

The Triangle Bikeway will provide a 16-ft wide, mode-separated commuter facility for active transportation within the I-40 right-of-way. When completed, users will be able to travel between Raleigh, Research Triangle Park, Durham and Chapel Hill accessing job opportunities along the corridor.

The Triangle Bikeway will leverage existing infrastructure, such as the American Tobacco Trail Bridge over I-40, as well as planned infrastructure in other projects, such as the pedestrian bridge that is currently under construction over Wade Ave as part of the Blue Ridge Road interchange project (as seen in red in the image). Utilizing these structures makes the Triangle Bikeway a more cost-effective project and increases the connectivity with existing bicycle and pedestrian facility networks.

“McAdams is a trusted partner for CAMPO to this day and we rely on them for innovative problem solving, quick response and high-quality planning solutions. Triangle Bikeway has evolved into being one of the region’s most anticipated projects, and McAdams will continue to serve as the source of needed expertise moving forward through the transportation planning process.”
