Couldn’t sheet pilings be used to dewater the area to be filled in and the muck removed to take care of the contamination issue? Probably how they will install the bents of the ped bridge anyway. My assumption was that we are in a landfill no longer political environment, in this case...

Honest question, is that OTP the result of actual improved operations, or less freqrency, schedule padding, loosening the definition of ‘on time,’ ect, ect. Obviously hoping for the former. Maybe Massachoicetts could weigh in?

“Trains would come every 5 minutes” …Literally one bullet later… “9 second headways” 😂 The wildest bullet isn’t even the airport travelator headways, but the expectation that gobs of people will happily pay $12 to ride Jacksonville Skyway Nord at most .9 miles!!! Maybe thats where the 9 came...

How is 60 mins of slow zone even possible?!? Wouldn’t that mean trains would take like an hour and a half Alewife to Braintree? That can’t possibly be righ… OH MY

l was actually thinking moving walkways but with bikes allowed when l typed that. 30 MPH nonstop service with 0 headways doesn’t sound that bad 😂. This may deserve its own Crazy Transit Pitch…

Compromise, replace the tracks with moving walkways. Im only half joking. When the T makes SEPTA look competent, drastic measures are needed. I would call the MBTA a joke, but jokes are at least funny. EDIT: Forgot the T’s record with escalators, nevermind.

Red line riders: “Awesome, this means we get to go faster!”

I think its “worth it” too, it would just be an another barrier added to the ones that have prevented air rights development for the last 60 years. ‘Enemy of good is perfect’ and all that. Another issue would be that unless the street was the width of the pike+ 4 RR tracks (not great), the...

Like the overall idea, but there will have to be a vent building if everything East of Mass Ave is decked over. Moving the surface streets over the centerline of the artery would definitely complicate that even if the vent building was built on terra firma due to the limited clearance to squeeze...

Does anyone know the linked vs unlinked trip split? I think l recall seeing an 80% figure somewhere, but l may just be making that up. If that figures true, wouldn’t a simpler solution just be to make the busses free? Free transit in general is a a bad idea since the money is better spent on...

States are unable to unilaterally erect tolls on interstates… half of the reason why is to prevent tolls at the border like this.

All true! In a vacuum, adding lanes to a limited access facility does increase capacity. 100% fact. However, the consensus in the Traffic Engineering field is that design year congestion will not improve in a healthy metro area due to induced demand unless the section widened was a bottleneck...

As much as l am loathe to defend NH state Pols, l really don’t think theres an ulterior motive. I think NH is just still stuck in the mindset that self evidently, more lanes reduce congestion. Most of the US still thinks the same way. MassDOT is actually one of, if not the most progressive state...

I understand that this incident wasn’t the MBTA’s fault for once, but l can’t help but laugh at the optics of the Orange line ‘derailing’ on 495 and wrecking the PM commute. I’m picturing one of the TV news stations doing a man on the street interview with a townie exclaiming “When l said l...

Town owned. On paper mostly the same standards, however what local DPWs actually construct…..

Doubly stupid when you consider how much of that $$$ was spent widening / shifting the entire freaking alignment through Windham to accommodate 8 lanes… which immediately reduces to 6 at the border (AKA where everyone is going). The only thing accomplished over a 6 lane cross section was letting...

In this example l believe it’s because the curb-curb width on this corridor is rather variable. As sneijder said, need more width for a car protected lane, so in this case it would lead to constant swapping back and forth between curb and travel lane sides mid block as the width changes...

*Looks nervously at SE Xway* Agree but typically those are old grandfathered routes; NHDOT could seek waivers but the facility still wouldn’t meet interstate design criteria. Theres no prohibition against mainline lane drops, but the ones on the Turnpike do not meet stripping/ taper length or...

Main reason the Turnpike doesn’t meet intestate standard is likely interchange spacing/ geometry standards. Interchanges spaced less than a mile apart are supposed to have C/D roads or grade separated ramps. The ramp radii are below spec if l recall too. Off the too of my head, l know the...
