The Diamond State Line study seeks to address the acute shortage of viable transportation options in a corridor shed that lacks both a direct interstate highway connection and the passenger rail option that other Northeast states and regions enjoy. It would also connect rural and environmental justice communities in the Delmarva peninsula providing enhanced access and mobility to activity centers such as housing, educational institutions, medical facilities, and retail and commercial services. It would restore passenger rail access to and from Delaware’s largest cities and provide opportunities for multimodal connections to the communities that swell in numbers during the summer. This project supports DelDOT’s goals of enhancing equity by serving historically underserved communities with inadequate access to life’s opportunities.
