Eh. The detour is indeed silly and eats up some time, but the flight-missing traffic doesn't really happen on those backroads. It happens in the tunnel itself, which is fundamentally flawed by not having dedicated lanes for HOV/transit.

Not accurate. Within that distance you have something like 6 lanes of traffic (if you count the various onramps and feeder roads) merging into 2.

So once you get past all that merging and into the tunnel, things move slowly but steadily - a good 20mph - 30 mph for most of the way. But while all that merging is happening, its all stop and go.

The Statepolice ramp would put the buses in front of all the merging, so they'd hit the 'slow and steady' zone directly.

So you're right insofar as there's no much of a backup on the haul road itself, but for an hour or so at PM rush the backup wraps up the ramp and around the vent building, and there's a backup on the covered part of the ramp and in lead-up to the tunnel propoer for several hours a day.

Its an absurd situation for transit. We're getting close to the point where the long-term cost in squandered vehicle capacity and driver pay might be approaching the the cost of just building an entirely new bus-only ramp from D street or SLW (not that that would ever make sense, but it illustrates the absurdity).

Just want to point again that the name, on maps, of the "State Police Ramp" is Silver Line Way. So clearly, at some point in the inception of the ramp system, it was intended for the Silver Line.

It is not MA State Police Access Ramp. At some point along the way they muscled in and grabbed control.
 
So what would happen if the T just told the bus drivers to start using the ramp? What are they so afraid of?

It says Do Not Enter - Official Use Only. I would say that a government body is an official use. Start rolling those buses on through!

Sounds like an easy fix! Why is it so difficult for the State Police to not see? Hard to believe that the T and the Mayor can't pressure the governor to change this rule. Crazy!

The goal is to repress transit ridership, so they have been successful in attaining their goals.
 
I like the dark grey concrete rather than the normal light grey.

But other than that....

A parked cruiser would magically appear at the top of the ramp.

After the tunnel panel collapse some years back, they did open the ramp to Silver Line buses for a while. It was fantastic.

Then they stopped once the tunnel reopened, because someone's sad little fiefdom had to be respected.
 
Why the hell do the police need their own ramp. They already have lights and sirens to get around traffic if need be.
 
Were damn near going to the forefront of modern day street level activation lately in new construction. Cities all over the world are building tall as hell, but Im starting to see that we have kind of popped out at the front of mastering the streets of our buildings. Its been growing and its finally at the rendering and pre construction stage with a little bit of finished construction but its happening now.

Since this is the swbtc thread look at the vehicle entrance to our new seaport parking garage for example. If thats not as good as it gets for tucking a garage into the background of the neighborhood IDK what is. You have to remember OMNI is going across the street to fully realize the area. You can hide the structure of a garage better than they are here (this side is very good the other side is exposed) although this is pretty good but as far as the egress for automobiles goes this is perfect with respect to the new neighborhood and its just a small piece of something happening all around us.

In 5-10 years into the foreseeable future you'll be able to look back and see that Boston really dominated the street level of this and the upcoming eras which is arguably the most important part of any city and we've always been better at that than most. There was a period where we got away from our roots but its back and were about to show how you build a great city in the modern era, where many cities are trying and coming up short especially these new upstart cities. Besides our hatred of extreme height its an inarguable fact that Boston is better at building a city than almost anywhere in the world and if we were allowed to build tall wed be better at that too. I think in 10-15-20 years it will have been realized the mistakes that were made along the way and how to build a modern city the ways all successful cities have been built in history... from the ground up. Were at the forefront right now of this. If one of these countries starts to build their Dubai in 10 years I think it will finally be able to be a great upstart/start from scratch city (which needs to happen to house this exploding world population). Theres going to be a lot of bad cities unnecessarily built in the mean time, when the means to build the greatest modern city of all time from scratch is at mankind's fingertips right now, but I think were going to lead the way as one of THE model cities for building the next great cities of the future. Metaphorically speaking were the Hong Kong/Shanghai of ground level, but well never compete with them for height. Were in a different class of city with cities like Paris and Amsterdam and we should be proud of that. Anyways thats not all in our past anymore thats now we can still build a city better than almost anywhere in the world and were doing it.

I agree it will eventually be hidden but you can currently see it walking from the Ft Point Channel back into the Seaport and it is quite the eye sore
 
Not sure if it's double-T construction or not, but garages are typically lots of pre-cast panels and pieces that arrive and are assembled quickly on site.
The double-t's have all penetrations pre-cored.

Garage construction is down to a science pretty much. Which makes sense since they are done at minimal cost.

It's double-tee.

Double-t means Tinker Toys, right? Cuz it looks that sturdy.

You must really like hearing yourself talk, because you do an awful lot of it whether or not you know anything at all about the topic at hand...

+1

But for those actually interested in the double-tee, it's called such because it quite literally looks like two T's put together:

^ Double tees are used over single tees because the web can be considerably shallower in double tees, which is crucial for maximizing floors of parking. On a single tee precast beam, the web needs to be deeper in order to achieve the same structural strength.
