Tracking Bridge Traffic Over A Summer Weekend


Just for laughs, we summoned up Google Traffic every hour or so during peak commuting periods.

We struck during mid-summer, which is a peak period around here. We did it before the end of the month, so we spared ourselves the cottage monthly-rental crowd.

We chose a weekend without some major event like a Scallop Festival or the Pan Mass Challenge. We did, however, choose a scorcher of a weekend.

Overall, I'd say we got as easy of a weekend as we could ask for in the summer. We may do another version of this when the PMC is in town (early August), just to see how it compares.

Here's the volume:

Bourne Bridge
Year round daily average (2011) = 42,505 vehicles
Summer daily average = 58,467

Sagamore Bridge
Year round daily average = 51,489
Summer daily average = 70,674

Here's what we found this week. We had no way of counting cars, even though we did do a few drive-bys just to make sure that Google Maps wasn't fibbing.



Friday, 5 PM.... 1 mile backup heading on-Cape at the Bourne Bridge, 1.5 mile backup at the Sagamore.

Friday, 6 PM.... traffic flowing freely over Bourne, minor delays approaching and crossing Sagamore.

Friday, 7 PM-Midnight.....hardly any traffic at all


Saturday, 8 AM.... 1 mile backup at Bourne Bridge, 2 mile backup at the Sagamore Bridge. Accident reported on Route 3 South just before the Sagamore Bridge

Saturday, 9 AM,... Accident at Sagamore still there, traffic back 4 miles, well past Exit 2. Bourne Bridge has 2 mile backup.

Saturday, 9:30 AM... Sagamore delays still back 4 miles, Route 6 East jammed to Chase Road.

Saturday, 10 AM.... Sagamore accident cleared, traffic still back 4 miles, pushing 5. Route 6 East jammed almost to Meetinghouse Road. 2 mile backup at Bourne Bridge, Scenic Highway jammed. Cranberry Highway filling up in Buzzards Bay.

Saturday, 11 AM... Route 3 South jam approaching Exit 3, Route 6 still jammed to Meetinghouse Road, entire Scenic Highway is bumper-to-bumper heading towards Buzzards Bay. Bourne Bridge jam 3-4 miles back onto the mainland. Bounedale Road, which may have 10 houses on it, has several ominous red sections on Google Traffic.

Saturday, 1 PM.... 3 mile backup heading on Cape towards the Bourne Bridge, accident just reported, this delay may grow substantially. One of our scouts tells us that Rte 25 heading to the Bourne Bridge sems to be moving 25 feet a minute. Both the Scenic Highway and the Cranberry Highway have multiple accidents, and are bumper to bumper. Traffic already on the Cape has eased up, just a brief jam after the Quaker Meetinghouse Road area. Traffic easin g up slightly approaching the Sagamore from Plymouth, maybe 3.5 mile backup now instead of 4.

Saturday, 2-4 PM.... 3 mile backups at both bridges, multiple accidents. Both rotaries are jammed. t 4 PM, there had been at least a 3 mile backup at Sagamore for over 8 hours.

Saturday, 6 PM on.... accidents are cleared, traffic flowing smoothly over both bridges.


Sunday, 9 AM... minor delays crossing Sagamore, a mile of bumper-to-bumper on traffic on Route 6 leaving the Cape. The Belmont Circle rotary in Buzzards Bay s getting full, might be church-related.

Sunday, 10 AM.... All clear, other than Route 6 leaving the Cape. The traffic jam is back two miles now.

Sunday, 11 AM... Mile long backup at the Boune Bridge, heading on-Cape. Six mile backup leaving Cape Cod on Route 6. Scenic Highway jammed.

Sunday, noon... Scenic Highway cleared, but Sandwich Road bumper-to-bumper. Mile long backup at the Bourne Bridge, Route 6 leaving the Cape is backed up to Chase Road.

Sunday, 1 PM... Route 6 jammed to Quaker Meetinghouse Road, accident in effect, 6A now jammed back to the Stop & Shop, perhaps people trying to get around the accident. Mile length backup at Bourne. Sandwich Road heading towards Bourne Bridge jammed a mile back.

Sunday, 6 PM.... very little traffic, minor delays leaving the Cape at both bridges. Ungodly good beach day, could be heavy volume later.

Sunday, 7:30 PM... The Exodus.... Rte 6 jammed back to Exit 6. One mile backup at Bourne Bridge. Sandwich Road and 6A have pockets of heavier traffic. Bumper to bumper on 495 around the Middleboro rotary.

Sunday, 9 PM.... One mile backup approaching Bourne Bridge rotary, pockets of traffic on 28 in Falmouth, Yarmouth, Harwich and Chatham. Route 6 approaching Sagamore back to Route 149.

Sunday, 11 PM..... except for a small stretch of 28 in Harwich, all traffic on the Cape is moving unimpeded.


Monday AM.... no Monday traffic, a sure sign of a slow summer weekend
