Cape Cod Traffic on Saturday
Saturday has its own shape: the weekly-rental turnover sends everyone over the bridges in a tight morning window, with the worst usually between 8 and 11 AM. Beat it early or wait until it clears.
On a typical Saturday, the calmest window is around 6 AM (~54 min) and the worst is around 3 PM (~88 min — about 63% over a clear run).
