In response to questions raised by the public, the N.C. Dept. of Transportation announced Tuesday (yesterday) it will begin a study on the economic impact of tolling along Interstate 95. The study, which will take six months to complete, will examine the positive and negative aspects of adding lanes on I-95 and paying for them with tolling or other funding. The department said the study will also look at what would happen if lanes or other significant improvements requiring additional funding were not made.
