Ever since the toll on Dumbarton bridge was increased, I have noticed a significant decrease in traffic along this route! I wonder if there is any data available on this. 880 on the other hand continues to be a nightmare in rush hour. The mess at the 237 junction has been fixed for the most part (the exit for the car pool lane will ease things more when completed). The 880 bottleneck happens now between Warren Ave and Dixon Landing exits. There seems to be stop and go traffic between these points at virtually all times (especially peak hours). Wonder why? I don’t think its 680 off Mission that is the cause. In general, Bay Area traffic is no where close to the way it was in the hey days of the valley (late 90s). The only reason not wish for the return of the hey days!! Oh well…

Isn’t the bottleneck near Dixon Landing because of the sudden change in the number of lanes? Haven’t been on 880 in a few months, but do remember that there was lane reduction problem around that area. -Brotherman

Yes, you are right. The lane reduction is one of the main reasons.
