Navigating Roundabouts

View the video below to learn more about navigating the roundabouts in the new interchange.

Community Partnering Committee (CPC)

This group of local business owners, residents, emergency service providers and other stakeholders, has developed communication strategies to help drivers travel safely through the work area and continue to visit the local businesses open during construction. The strategies are part of a Construction Communication Plan and rely on communication media which the Committee members currently use.

Pedestrian Bridge

A portion of the pedestrian bridge that was removed during the construction of the updated New Stanton Interchange has found new life on the Sheepskin Trail in Fayette County.
