The extra lane they created seems to have no effect come rush hour. Commuters are still clogging side streets as a short cut. The amount of traffic on Camino Ramon and SRVB are still being used as a way to bypass on I-680 when it's backed up.
Also, I thought they were going to replace the trees they cut down along Camino Ramon ... All I see is dirt and weeds.
