Starting this morning my usual drive time from the suburbs of Philly into NJ increased dramatically by 50% then normal. At first I thought there was an event on the route, but all possible routes were increased by the same amount. I continued on the normal route and the arrival time slowly adjusted to the normally expected arrival time. Anyway...checking a drive for later this afternoon gave me the same type of situation although the drive time was close to double what it should be. Again...no events showing on the route.

Anybody have any thoughts, explanation for this anomaly?

Thanks!
