How about the Basin Reserve?
Here’s another “peanut”
Is that actually considered a roundabout?
Very good. Thank you.
There’s a new one near us (not on Google Maps yet).
While the “circle” part is normal, what they did to connect stuff is weird. (N at top.)

There are houses on the W side, so they built it off to the E side. The road on the E is new. But they didn’t line it up with the W road.
Traveling N/S is practically a straight line.
If you want to go N and take the W road you have to go completely out of the circle and turn sharply around a concrete median. Of course if you’re coming in from the W and want to go N then you don’t enter the circle at all and it’s a stop sign. No “keep moving if it’s clear” efficiency of a circle.
I have no idea why they didn’t line this up better.
With two stoplights, it’s certainly closer to a roundabout than my second link. I haven’t been on Seminary Road in quite some time and forgot about all the stoplights.
Here’s one that is signalized and has a major artery cutting thru it. Before those features were added decades ago, it had one of the highest crash rates in Massachusetts, maybe still does. I had two fenders crushed while commuting thru it in the '60s, in separate incidents:
That looks like it would work much better if they put that artery on a bridge over the roundabout.
It was planned to do that as part of a planned extension of then I-95 northeastward from Boston but the then governor opted for using all the federal money to go to expand the MBTA subway system. Here’s the history of that (map at the link).
History
The original plans called for I-95 to run through downtown Boston. The highway would have progressed from Route 128 and Readville, followed the Southwest Corridor, joined the Inner Belt in Roxbury, heading east, and joining the Southeast Expressway at South Bay, then north to the Central Artery at the South Station interchange with the Massachusetts Turnpike/Interstate 90, and connecting with the Northeast Expressway at the Charlestown banks of the Charles River.
However, due to pressure from local residents, all proposed Interstate Highways within Route 128 were canceled in 1972 by Governor Francis Sargent with the exception of Interstate 93 to Boston. The only sections of I-95 completed within the Route 128 beltway by the Massachusetts Department of Transportation were the segment known as the Northeast Expressway north from Charlestown to Saugus, which is now part of U.S. Route 1, and the Central Artery, which cut the North End neighborhood from downtown Boston proper until the Thomas P. O’Neill Jr. Tunnel essentially submerged the old Central Artery’s traffic load below ground level in 2003. The Southwest Expressway and the Inner Belt highways were among the Sargent-canceled highways.
Original 1955 Yellow Book plan showing the southwestern routing of I-95 to the Inner Belt. The modern I-95 follows the outer belt shown on this map (now considered the “inner” Route 128 compared to the “outer” I-495 which is not shown, and which started construction 2 years after the study).
Between 1972 and 1974, plans were to extend I-95 along a northerly extension of the Northeast Expressway to Route 128 in northwestern Danvers. During this time, I-95 was officially routed along Route 128 from Canton to Braintree and north along the Southeast Expressway (also designated Route 3), from Braintree to Boston, then following the Central Artery, and continuing along the Northeast Expressway in Boston, Chelsea and Revere.
When the Northeast Expressway extension (between Saugus and Danvers) was canceled in 1974, I-95’s route shifted to its current routing along the perimeter highway (Route 128) and I-93 was extended to meet I-95 in Canton. For several decades, plans for the abandoned roadways could still be seen going from the end of the Northeast Expressway to the Saugus River in Saugus in the form of a graded but unpaved roadbed. Much of this was removed during the early 2000s. At the US 1/Route 60 interchange, one can still see unused bridges and ghost ramps that were originally intended to carry I-95.
I have to take some of that back, as it’s been a long time since I lived in the Boston area and I’d forgotten some details of the highway plans for the Revere and North Shore area. I just found this thread and Bell Circle is at the bottom center of the first map/photo, just above the word “planning”. The n.e. extension was to bypass the circle, thereby greatly reducing the traffic volume in it. Bell and the other two circles shown on that photo have been there since around the late '40s/early '50s I guess.
At first I thought this was from the SDMB but it just shares the v-bulletin posting system
I just spoke to my son last night and he told me it had been canceled, that the nature of the intersection made it unfeasible.
There was a big oval-shaped one in South Jordan, Utah, but they’re currently in the process of tearing it out and building an overpass for Bangerter Highway.
Thanks for getting back on that, Mr Psychohistorian (or do you just go by Mr Psycho for short?). I half expected you’d forgotten, but you came through. Way to go.
Re: my previous post.
is apparently still broken.Maybe you should go back to the old skin. It still works there. There’s a selection field for that in the bottom left of each page.
Nothing will fix that intersection short of not allowing any turns ever.
Brighton Michigan has a triple (sort of). It is a double on one side of the highway with a single on the other. It is kind of odd because of how the freeway ramps come in.
That’d be a neat thing to see in Cities: Skylines.
Roundabouts are much more common in the UK and unusual shapes are usual.
The magic roundabout in Swindon has an inner and outer roundabout with 5 mini-roundabouts around it. You travel clockwise on the out part and anti-clockwise on the inner, switching directions as you go around the mini-roundabouts.
Other towns have followed this pattern, so it must work!
Pretty standard one, then they stuck no less than eight sets of traffic lights upon it
sigh (well it worked up 'til the second page)
