Traffic circle construction

A new roundabout at Md. 180 and Mount Zion Road was opened to traffic Tuesday afternoon.

After two months of work, Frederick County's newest roundabout is open for business.

The roundabout at Md. 180 and Mount Zion Road opened to traffic Tuesday afternoon, according to the State Highway Administration.

Officials had waited until June 20 to shut down the intersection until Frederick County Public Schools let out for the year.

The $3 million project was handled by Concrete General Inc., of Gaithersburg.

Some residents had questioned whether a roundabout was really needed at an informational meeting that SHA officials held with residents in Jefferson in February 2018.

Officials say the design substantially reduces the number of crashes, especially so-called angle crashes, which cause more injuries than sideswipes or rear-end crashes.

Statistics show 20 crashes at the intersection between 2012 and 2018, and eight police-reported crashes in 2018, according to SHA.

The intersection is used by about 4,000 vehicles per day.

Meantime getting through Jefferson from the south remains a real chore. I moved here a year and a half ago and you can measure the progress on this project since then with a hardware store tape. Day after day of workers showing up @ 9AM, packing up at 3 PM if they show up at all. Day after day of repairing problems with what's already been done. Day after day of no workers at all. It'll be done a year from now? Hah!

From the photo it looks like it was built correctly. Hopefully its large enough to be effective. I'll have to take a run over there to see how well it was done. There should be more of these around and drivers ed classes should teach about these.

"Some residents had questioned whether a roundabout was really needed" Them roundabouts are way to complicated for me to understand, gimme a stop sign that's easy to figure out.

Thank goodness! I use this to avoid travelling on 340. I take 180 to Jefferson then approach Rte. 15 South from Mountville Road. It is a longer way to go but I hate the traffic on 350. Avoiding that stress makes for a better start to the day.

This is a good proactive move. That wide-open intersection was an invitation to speed, and cars traveling west coming over the brow of the hill can be on top of you rapidly.
