The fallacy in your logic is that maintaining three lanes of traffic in each direction is the same as reducing bottlenecks. Yes, maintains a constant number of lanes in a corridor does reduce bottlenecks when traffic volumes are consistent throughout the corridor. That however is not the case on Woodhaven. The volume fluctuates.

Second, you are ignoring the fact that three are presentlyat least four lanes in each direction so you are also reducing capacity by at least 25 percent, increasing traffic volumes on the remaining lanes. At some intersections, there are extra lanes for right turning movements. Those are being eliminated requiring those cars to queue up in the through traffic lanes instead of the turning lane, further increasing capacity. So with no reduction in traffic volumes, and there is no indication whatsoever that SBS will result in fewer cars, congestion can only increase.

Also, part of DOT's rationale is to separate through traffic from local traffic so that two lanes will be through traffic on the main road with local traffic on the service road. That only works for reducing congestion if two thirds of the traffic is through traffic and one third is local traffic, that is traffic that us only on the service road for a few blocks.

In reality, more like 80 percent of the traffic is through traffic which means that many through traffic cars will be forced to use the slower service road which will have cars stopped in order to park or slow down to make a right turn as well as stopped school, buses and delivery trucks. That will make the service road very slow for through traffic, but will be used by through traffic anyway when the main roadway will be barely moving. Other traffic will resort to use parallel residential streets increasing traffic on those streets.

So the constantly changing number of lanes which only exist in a few places (since DOT already striped off areas where the roadway widens) do not increase bottlenecks. They actually reduce them by providing extra lanes for right turns.
