Project Limits:

The intersection of SR 3 - Marsh Road (N023) and Harvey Road/Grubb Road (N209) in Wilmington, New Castle County, Delaware.


Project Need:

A traffic study has been requested to analyze safety and operational improvements at the intersection. Currently, through vehicles are illegally using the right turn lanes to bypass left turning vehicles. These illegal movements are creating safety and operational issues.


Project Overview:

The scope of the study was to evaluate the lane configuration of the intersection from shared through/left turn lanes and separate right turn lanes along northbound and southbound Marsh Road as well Grubb Road to shared through/right turn lanes and a separate left turn lanes along these approaches. The improvements will also require improvements to the signal infrastructure at the intersection.

Thank you for your participation in this Virtual Workshop. The Virtual Workshop has concluded and indicated that 81% supported the lane configuration changes at the intersection. Considering the results and information provided in the traffic study, we are recommending the new lane configuration be pursued. The supporting documentation and recommendation will be submitted to our Traffic Design Section to start programming the design work. This type of effort will require a detailed design to understand right of way, drainage, utilities, soil conditions, etc.
