UPDATE: traffic flowing on Rancho Cal Road in both directions through the roundabout as of this morning. However, tha project is not yet complete so expect some slowing due to cones and construction crews.

Yes! Finally - the roundabout is open! Just used it this afternoon to pick up my daughter from school.

However, do be CAREFUL and go SLOW. The county made the lanes incredibly narrow and winding. I give it 30 days and there will be an accident because someone is not paying attention due texting, talking on the phone, speeding or DWI. Also, watch out for the workers - they are along the road and inside the roundabout installing landscaping. Top heavy vehicles, like the shuttle buses, will have a quite a sway while in the roundabout.

Would still probably avoid Weins, Ponte and South Coast for at least another week or so.

Ooh, can't wait to negotiate it on my next visit! I just got back from Sedona where they have embraced their "inner roundabout" with a vengeance--but from the amount of black tire scuff on all nearby curbs, and ON the roundabout, drivers have a steep learning curve!

Vnrose - I've been to Sedona - and their roundabouts are soooo much easier than this one. This is an lawsuit waiting for an accident.

They've installed 4 inch curbs at a 90 degree angle with the road all along the roundabout and about 300 feet on both sides of the narrow lane as you enter/exit the roundabout. At least the roundabouts in Sedona have negligible curbing and don't 'guide' the car from the roundabout for another 300 feet after exiting or as you enter.

Add to this that its in the wine country with its inebriated drivers on cell phones or texting, one hand on the wheel, speeding to the next winery.

Juan Perez of RCTMLA and his crew really messed it up this time. I'll bet you they will be making 'adjustments' within a year, but not before some serious accidents occur.

I just recently "navigated" the roundabout on a fairly busy day and traffic was flowing nicely! Once the landscaping is complete, it will be a beautiful addition to wine country!

@ Temeculatourism - so long as the county uses some common sense with landscaping that doesn't inhibit sight lines - but the county hasn't been known for its common sense in the past. Apparently, you missed all of the black tire marks along the 4 inch curbs along the roundabout - pointing to the fact that the driving public is having difficulty with the entry/exit points. Also, I've noticed a lot of confusion of drivers using the roundabout during peak commuting hours. Time will tell if this was a huge mistake, which I think it was.

After driving in the UK for weeks a couple of years ago, I find roundabouts to be the instrument of the devil. Horrible things and US drivers are not familiar with them to know the proper etiquette for getting into and out of them properly.

I would recommend that those planning on heading to Temecula (which is lovely) should pay close attention when navigating this section of road.
