In the recent copy of the Arroyo Grande Stagecoach Express, the city said it was making progress in addressing the “deficiencies” at the Brisco Road/Highway 101 interchange.
One would think that the deficiency would be the additional traffic through the underpass because of the interchange, but the city proposed a “roundabout” at the foot of Rodeo Drive on Branch Street that would include on and off traffic from Highway 101.
This addition would be a mere few hundred yards from the underpass, and the traffic load would be the same as before.
Nothing gained there.

Roundabouts are used to replace four-way stops at the intersection of two roads to prevent accidents, increase the flow of traffic and replace the traffic-limiting stop signs.
The proposed roundabout would do none of these.
It would slow and congest traffic on Branch Street, which now flows directly to Grand Avenue.
At present, there is only one stop sign, and that is on Rodeo Drive. Removing it will not have any positive effect on traffic flow or throughput. Adding the on/off ramps to/from Highway 101 would be equivalent to leaving them where they are — but after spending a significant amount of money.
I live on the east side of Highway 101 and will be slightly inconvenienced by the closure, but reduced traffic in the underpass will make up for it.
