Roundabout Construction

BroadHopper · 11-20-2012, 02:55 PM

I remember a semi tipping over the cobbled area after they finish the Meredith roundabout. Something about the slope of the cobblestone area induced tipping.

Anyway, I like to travel the path of least resistance. The cobblestones provides more resistance than a concrete paving. I can save a couple of cents in gas driving straight through the Weirs roundabout.

I love my Jeep!

OK so who is going to be the first one here to drive around and around and around and around and around and around and around......

I wonder how many G's I could muster in my sports car on that concrete inner circle?

I am going to set up a TIRE business just down the road. Tire "Scrubbing" (Particularly the FRONT tires) around the rotary is going to wear out your tires faster.

Both of the roundabouts in Plymouth and Meredith have natural grey granite blocks or cobbles in the concentric infield area designed probably to be maybe like a sort of rumble strip or something for the rear wheels of large trailers like the standard 53' tractor trailers when their rear wheels automatically track on a tighter radius then the front steering wheels of large trucks.

So, if both the Meredith and Plymouth roundabouts, constructed about three years ago, went with very nice looking granite cobbles, then why the heck did not Laconia follow their lead and do the same thing.......huh.......why not?

Here's my two cents on why it is what it is........for Bike Week.....the smooth concrete will be adapted into a motorcycle "WALL of DEATH" by constructing a smooth concrete wall that blends with the existing concrete apron. ......and then it's ready to ride.......ladies & gentlemen.......please start your engines for our next Wall of Death presentation...... www.americanwallofdeath.com/ ..... down at the new Weirs Beach 1.1-million dollar Roundabout!

NB...First thing I looked at, the tire marks on the curbing. Already plenty of rubber on it.
I'm dying to see what the curbing looks like after the first plowable snow.

Just drove through. Lots of black rubber marks on curb.
Better check on the current price of car alignments and new tires.

Why didn't these designers place slanted curbing on sides? At least on the turning right sides. Roadway is too small. OK for some cars. But get bigger then the average car and there are big issues.

All might look good on paper. Not good in reality.

Please don't dare me...I'm bored, less than a mile from the roundabout (The Weirs Centrifuge) and will gladly use my newest iPhone app!!!
