Sagamore vs Bourne Bridge — Which Is Faster?

The honest answer: it depends on your starting point, not the bridges themselves. From Boston and the South Shore, Route 3 funnels you to the Sagamore; from Providence, Connecticut, or New York, Route 25 makes the Bourne the natural crossing — detouring to the "other" bridge only wins when your natural approach is jammed and the other is not. Use the dashboard above to compare both crossings live, and check the typical patterns before committing to a detour.

On a typical Friday, the calmest window is around 9 PM (~58 min) and the worst is around 2 PM (~110 min, up to ~116 on busy days — about 104% over a clear run).
