North Main / Highland Traffic Circle

Postby mrmtholly » Wed Mar 18, 2015 1:25 pm

Mount Holly Traffic Circle Proposal per the Mount Holly Strategic Plan adopted in 2008 page 6: Downtown and Riverfront Initiatives - Install traffic circle at Highland Ave / North Main Street. (We already spent the $$$ for the study, the plan, and the community input on this. There is nothing stopping us from doing this.)

The attached concept is what should be installed. Why?

1) Too many freight trucks travel 273 to/from the industrial facilities north of this intersection. The traffic calming from the circle and from the raised pedestrian crossing would make it more likely a freight truck would favor the Hwy 16 option to travel to/from the interstate network. 273 is not built for freight traffic and often needs repair due to use beyond its capacity.
2) Speeding traffic is a concern north of this intersection
3) This is an ugly intersection for a gateway entrance into the downtown area. And Mount Holly is attempting to entice quality development in the north.
4) This intersection does not well-accommodate pedestrian traffic that walk downtown
5) During times of congestion, the traffic light does not help matters
6) Often bicyclists travel on 273 via both sidewalks and on the streets. This design accommodates both ways.

The same can be done a little closer to downtown for much less $$$$:

Here is a NC53 with 9,000 vehicle/day and significant trucks with a proposed roundabout. Look at Page 13:

As to #2, a traffic circle won't have any effect on speeders. Once they get through the circle going north, they will speed up just as the do from the traffic signal now. If you don't believe that, just go to Kendrick Rd/Gaston Day School Rd. area and see what happens to the traffic after it goes through that circle.

Good. A real-life traffic circle intersection as a data point to consider.

I have noticed that Southbound traffic on 273 actually SPEED UP when they see the light is green. It's most noticeable when what is speeding up has 18 wheels and makes the ground shake as it goes by. A traffic circle would require traffic ALWAYS slow to a controllable pace through the circle at least. Given there were 2 accidents within a block of that intersection in the last 6 months, this might be a good idea.

If the speed limit were reduced to 30mph, a "road hump" could be used a little further north so that traffic exiting the traffic circle would not speed up much in order to pass over a road hump designed for 30 mph.

Cars can stop and navigate better than full-loaded trucks. If a traffic circle were employed and if it had raised pedestrian crossings, I'm betting fewer trucks would choose that route and certainly would be traveling more slowly.
