Hi all,
Regarding the ongoing discussion about "the Throat" at the Rt 90 Allston project, I have long been advocating for reducing the lanes on the Turnpike. It would allow for a much better design with no degradation of traffic flow.
See my recent comments about this below (Sept 24, 2025; July 9, 2025; April 27, 2025; April 18, 2025; July 4, 2024)
The Allston turnpike plans need to be revised to have a 3-lane design. Consider this a compromise... because the more radical solution is to deconstruct the Turnpike completely and turn it into a boulevard!

Hi all,
It's a shame to see some of the lower-cost neighborhood projects unfunded. Perhaps state/local funding can make up the difference. Maybe there are some cost cuts that can be implemented?
As for the larger projects, like the Allston Turnpike project, I remain opposed to expanding the turnpike from 3 lanes to 4 lanes and believe this is counterproductive towards our transportation and climate goals. By keeping the Turnpike a consistent 3-lanes,
this may reduce the cost of the project and allow for more space otherwise.

Andreae and all,
Honestly, folks, if the state and DOT don't reconsider reducing the lanes on the Pike at the Throat, I wouldn't be unhappy to see the project paused.
Going "back to the drawing board" is not necessarily a bad outcome!

All,
I am completely aligned with Emily on the matter of sensible planning for the number of travel lanes for the Rt 90 Allston project. But here is the biggest impediment, as quoted from the Streetsblog article:
""If the highway were reduced from 4 lanes to 3 lanes in each direction, the new capacity would be about 5,300 vehicles per hour'" in each direction.
Hall then asserted that traffic would overwhelm a 6-lane Turnpike."
Ever since I guy named Downs (🙂) first described the "Fundamental Law of Traffic Congestion" in 1962, traffic engineers and planners have been obstinate in failing to understand the basic realities of roadways.
Also, modeling should be done with the expectation that our population will not only get older and drive less and use more transit, but that our overall population will decline, as described in this recent official US Census report:
The greatest decline would occur if there were to be a zero-immigration scenario, in which case the US population will be 226 million in 2100, which is about 100 million fewer people than now.
The basic data inputs for this project should not be determined by the traffic/highway consultants (who are prone to outdated highway-centric thinking) but by the project management team or by a task force of citizens and public officials. I think it would
be safe to assume that there will be at least a 20% reduction in traffic demand
by the time this project is completed.

Hi all,
As I've said many times, there is no need to expand the Turnpike. It should be three lanes, not four. I'm glad that others are also recognizing the fallacy that the pike needs to be widened and expanded.
Of course, in the last e-mail I sent to this group on this topic, I called for completely dismantling the "Turnpike extension." However, I don't think people are ready yet to accept such a radical solution! Maybe the best we can hope for is a 3-lane Pike in
Allston, rather than a bloated 4-lane roadway.

From my note on July 4 2024:
Also, the current plans show that the Pike shrinks from 4 lanes to 3 lanes at the Cambridge Street exit eastbound, mainly because of the presence of new slip lanes on either side that are 2 lanes each. Why then would the turnpike have to re-expand to 4 lanes
for a distance of just 2 miles east of here when it once again shrinks to 3 lanes at the Prudential Center? ... The 3-lane option would help alleviate the issues at the "throat' where Soldiers Field Road and the Pike come in close proximity.
