You seem to be completely ignoring what he said about this being entirely out of line with the stated goals of reducing single person auto trips by 50%cden -- not only is it obvious that you've never driven Storrow or the Pike at rush hour -- it's fairly obvious that you haven't even looked at the TV Traffic maps.
Under ideal circumstances the traffic flows slowly if acceptably. Add in any disruption and its essential to have a Plan B. One compromise would be keep the number of lanes but make one each way a breakdown lane [open for travel during rush hour].
The major improvement to the rebuilt Storrow and the Pike is in terms of auxillary structures in addition to the travel lanes. Both the Pike and Storrow were constructed in an era before universal breakdown lanes and similar auxiliaries to the travel lanes as well as inadequate arrangements for merging. I suspect that you could give up one full travel lane for breakdown and expanded merging. The footprint would not get any narrower than it is today -- but it might function more efficiently.
Ideally all the auxiliaries would be added to the existing four travel lanes and even more ideal -- more exits [W bound] and entrances [E bound] would be added where they were never included in the original layout.
Citylover -- it doesn't work that wayThe federal gov't isn't allowing any new sections of breakdown lane travel and that is honestly worse imo than just not having a lane. Either way it would never be approved so that doesn't matter. I think taking it down by one lane in each direction would be okay and would in the long run encourage less people to drive into the city and instead take transit.

That is just a political statement with no value what-so-ever. There is only one way that the goal could be achieved -- the same way Detroit did it -- empty the city out by killing the economy -- it has the same reality associated with it as the Red Sox promising to be in the World Series any given year between 1920 and about 1999City's GoBoston 2030 plan looks to reduce the percentage of people driving alone to work by 50% by 2030,
