Was the route for the Central Penn Line chosen because it is less expensive than upgrading the existing Transco pipeline?

The existing Transco pipeline system is extremely capacity constrained in New Jersey and Southern Pennsylvania, as it operates in very densely populated areas. The Central Penn Line has been designed with fewer landowner and environmental impacts than could be accomplished by adding the same amount of looping and compression to the existing Transco pipeline. Attempting to do so would result in greater impacts to residential and development areas, land uses, forest lands, agricultural lands, wetlands and water bodies. In addition, because of encroachment of residential and commercial structures along the Transco system, certain areas would be nearly impossible to loop and would require other greenfield portions to be constructed, further increasing the overall impact of the project.
