    Boston Harbor Flood Protection Projects

    Per Bigemans link; it really is a remarkably sharp cutoff at 5’ above MHHW. 4’ is almost unscathed and everyone would go into work the next day if some small scale defenses are implemented. But at 5’ the Charles and Mystic dams are overtopped and its Katrina level inundation. (Green represents...

    Wakefield Developments

    Pretty hideous but l’m hoping all these units next to the station will be the catalyst for a couple new restaurants to go in downtown and on Albion Street. Downtown Wakefield has good bones but only has 3, maybe 4 establishments open past 8 worth going to.

    MBTA Buses & Infrastructure

    Permanently deleting the 136 and modifying the 137 to run the long way via 136’s old route to Reading. 137 is downgraded from 30 to 60 min service and no longer stops at Oak Grove, lengthening transfers to the OL. Significant downgrade between Malden and Wakefield center from 2019 when 136/137...

    This is why best practice is to have those overhead variable message signs blank unless there is a specific message worth displaying. Every one from 495 in was probably displaying a “Road Work Leveret Connecter, Seek Alt Route” message, but since they usually only display “Use ya blinka” or a...

    Green Line Extension to Medford & Union Sq

    If differential settlement is expected to be over a foot, we have wayyy bigger problems than sloppy looking poles :). Since l dont see baseplates, l would put money on all the piles being the same length, but with varying depths below grade. If they’re driven, makes sense to hit refusal at...

    Green line service is back between Government Center and N. Station. Still skipping Haymarket stop.

    Bowker Overpass replacement?

    Otherside of the same coin, the Pike would be much faster for those heading to 93 S by avoiding the light at Leveret and the Tip tunnel. That’s why a real traffic study would be needed to determine the trip distribution, effect on Pike/ Southbay interchange operations, and induced demand...

    Bowker Overpass replacement?

    The justification for a ramp here is that Storrow is 1) serving a high percentage of traffic exiting the city in addition to inter neighborhood trips and 2) is a lower capacity facility than the Pike. The Charlesgate-Storrow interchange serves long distance traffic from Longwood and the...

    Reasonable Transit Pitches

    Out of curiosity, I looked at the MVRTA bus routing from Haverhill to Lowell. Yikes. This is why the sterotype that only poor/desperate people take the bus exists. 2 hours with a long diversion to the Loop in Methuen and a transfer at Lawrence. For comparison, this is about a 30 minute...

    Green Line Extension to Medford & Union Sq

    Im assuming those limits are just for the Union Square branch, which is understandable given the curves and gradients. The way it written though makes it seem that those limits would also apply to the Medford branch which would be asinine.

    Green Line Extension to Medford & Union Sq

    N. Station to Union is almost exactly 2 miles. 10 minute trip is 12 MPH average. I think 12 MPH should be the floor rather than the ceiling on brand new/heavily rehabbed grade separated rapid transit. Is there an overzealous safety culture at the T (honest question)? EDIT. From page 1-4 of the...

    Green Line Extension to Medford & Union Sq

    I also thought stop signs were only for cars ¯\_(ツ)_/¯ The motorman said the limit at first was 3(!??) MPH. Assuming he meant for testing. Again, Im hopeful they will at least permit 20 MPH (annoying but relatively minor travel time impacts). I’m doubtful trains will ever cruise at 40 though...

    Green Line Extension to Medford & Union Sq

    Took my first ride today. Snagged the “railfan” seat both ways. Came in to Union via the left hand track (no path crossing) and noticed a stop sign on that track too prior to the station. Also chatted to the motorman and asked about the speeds over the viaduct; 10 MPH limit and said it may or...

    Cape Cod Rail, Bridges and Highways

    No idea why the mainline isn’t blasted through the middle other than to save the bushes. Definite head scratcher since all those signals don’t exactly make it a low cost alternative. That said Im also 128% for it.

    Cape Cod Rail, Bridges and Highways

    Bikes, pedestrians, and horses are apparently allowed to use the rotaries on 28, but are prohibited on the mainline. These signs are posted just downstream of each rotary and on interchange ramps. Outright prohibited on 25, 3, and 6 until Orleans. Cycle accommodations should and will be provided...

    And then some. Point l was trying to make is that a decent size market basket going in may be required to pay for roadway improvements. $14 million is way more than what most developers pay; however DBC is so large it still isn’t enough imo.

    Dorchester Bay City (nee Bayside Expo Ctr.) | Columbia Point

    Another thing to note is that their congestion analysis doesn’t look as bad as actual operations since the existing network operates at LOS E or F already. If one just glanced at the results, a degradation of one letter grade from an E to an F or holding constant at an F doesn’t look that bad...
