Last evening as I was headed South on 15/29 cutting over from I-66 to Fredericksburg, I called home to have somebody check Google traffic for conditions around Rt 17, I-95 and Rt3. The report was good, but as approached the left hand turn onto RT 17 at the Sheetz, it was backed up quite a bit. So I kept going straight and came in the back way via Carrico Mills Road. As I passed the left turn from 15/29 to 17, my GPS indicated a 7:14 arrival time at home via Rt 17 and I-95. I got home a 7:20.
Given the likelihood of a more than 6 minute delay up around Rt 17, I-95, and Rt 3, I think Carrico Mills just became my default route home. I’ve always used that route around rush hour when I knew Rt 17 would be backed up, but my perception was that the back route was more like 15-20 minutes longer.
