Allston presentation link

A lot of people have asked for the Allston presentation that I gave to the Task Force. It's here. Enjoy (?).

Update 9/28: Here is the "dueling" presentation from ABC. Dueling very much in quotes, because I think they are 90%+ the same. I've worked a lot with the authors, and think both have merits. (You may even see a slide in there from me :)

Something is very wrong with MBTA project procurement

When the news broke about the escalating costs of the MBTA's Green Line extension to Medford and Somerville, I can't say I was surprised, but the cost numbers have now escalated in to absurdity. I'm not an expert in the bizarre project procurement, but the costs are now to the point where the project really should be reviewed and rebid, even if there is a delay. It is far beyond what similar projects cost in other cities, and the project procurement team at the T should be removed to allow someone from the outside to bid the project.

How ridiculous are the T's numbers? Let's take a look at them, and compare them with some other projects:

Minneapolis-Saint Paul Green Line
Distance: 11 miles
Cost: $957 million
Cost per mile: $87 million
Completion date: 2014
Engineering difficulties: rebuilding bridge over Mississippi River for light rail, rebuilding the entirety of University Ave lot line-to-lot line, junction and flyover with existing Blue Line in Minneapolis. Likely cheaper than the Green Line extension. But not 9 times cheaper.

Los Angeles Expo Line Phase II
Distance: 6.6 miles
Cost: $1.5 billion
Cost per mile: $227 million
Completion date: 2016
Engineering difficulties: Several grade separations, parallel bike/walk facility. Still four times cheaper than the GLX.

San Francisco Central Subway
Distance: 1.7 miles
Cost: $1.6 billion
Cost per mile: $941 million
Completion date: 2019
Engineering difficulties: full deep bore tunnel in a seismically active area with three underground stations. In a rather expensive city to work in. And barely more than the GLX, which is being constructed in a grade-separated right of way!

Seattle University Link
Distance: 3.1 miles
Cost: $1.9 billion
Cost per mile: $613 million
Completion date: 2016
Engineering difficulties: full deep bore tunnel below the water table in a seismically active area with two underground stations. And quite a bit cheaper per mile than GLX.

Now, here are two MBTA projects:

Red-Blue Connector
Distance: 1300 feet
Cost: $750 million
Cost per mile: $3 billion
Completion date: ???
Engineering difficulties: Cut and cover tunneling below the water table in a constrained corridor. Certainly no greater than building the Central Subway in San Francisco, yet somehow three times more expensive. This should probably be in the lower end of the $100 to $200 million range, not three quarters of a billion.

Green Line Extension
Distance: 4.3 miles
Cost: $3 billion
Cost per mile $700 million
Completion date: 2019?
Engineering difficulties: Relocating existing parallel commuter rail line, building a flying junction, parallel bike/walk facility.

Here's the thing: none of the engineering challenges faced by the GLX and RBC are unique (flying junction in Minneapolis, parallel path in LA) or insurmountable, yet the costs are an order of magnitude greater than in other cities. The Green Line Extension is between three and nine (!) times more expensive than similar light rail lines, and more expensive than new light rail lines which are being built using deep bore tunneling techniques, which are not cheap. High construction costs? Seattle and San Francisco have pretty high construction costs and labor wages too. The remaining GLX construction should be rebid mimicking the processes used in these cities with a new team at MassDOT, and if costs aren't cleaved significantly, there should be a full investigation as to why.

The for the Red-Blue connector, which everyone agrees is a very important link, somehow costs three to four times what much more complex projects cost in Seattle and Los Angeles (while the Blue Line uses heavy rail equipment, it is the same diameter as light rail trains). The project is only 1500 feet long, doesn't require a deep bored tunnel, and has only one station at Charles, and the headhouse there already exists with provisions to connect it to the Blue Line. The fact that it costs $2.6 billion dollars per mile is laughable. For the cost of one mile of construction in Boston, Minneapolis could build 30 (!) miles of light rail, and Seattle four miles of deep bore tunnel (about what you'd need for the North South Rail Link) and at a cheaper rate per mile than the Green Line Extension. It's not even in the ballpark of reality, and whoever at MassDOT comes up with these numbers needs to be sent out to pasture.

There is no logical reason why a project in Boston should cost triple—or more—what a similar project costs in another city. $2 billion was suspiciously high. $3 billion means that a lot of people are on the take, or that money is being pissed away. I'm all for transit expansion, but not at these prices. An outside manager is a good start. But this has been a problem for a long time, and the T's project procurement staff has shown no ability to do their jobs. Get rid of them.

This is correctable. It needs to be corrected.

Quick thoughts on the ½ block Mass Ave bike lane

I took the liberty to bike home this morning from running across the Harvard Bridge to check out the new bike lane there (sans phone, however, so no sexy pictures). Here are some quick observations:

  • It needs flexi-posts. Too many drivers are used to using it as a right turn lane. Once installed, they should preclude that, which is where the real safety improvements come (that and No Turn on Red markings, which are long overdue; perhaps DCR and MassDOT will match with NTOR on the Cambridge side of the bridge). Whatever system is put in place needs to be kept year-round, with a snow-clearance plan (which includes the bridge, which MassDOT did not clear this past winter).
  • Flexi-posts would be nice on to the bridge, which is always a bit harrowing with catch basins on the right and traffic on the left, but that would mean it would be hard to pass slower cyclists, a relatively frequent occurrence. Perhaps intermittent (every 30 meters/Smoots) posts that would still allow cyclists to change lanes would work. It's also MassDOT territory and interagency cooperation is not a thing in Massachusetts.
  • Once in place, there will no longer be the merge/bus stop/right turn hell that has been the situation there for years. (Or as vehicular cyclists would call it: paradise. To be dead serious for a moment: the previous situation at Mass and Beacon was exactly what vehicular cyclists advocate for: a free-for-all with bikes acting as cars. People died because of it. It is high time for the vehicular cyclists to be banished to the dustbin of history.)
  • The bike lane westbound/northbound on Mass Ave (on the other side) has been striped quite wide—at least 8 feet—coming in to Beacon, where it shares a bus stop. This means that both travel lanes are just nine feet wide. If nine foot lanes are okay (and they should be) you could dramatically improve Mass Ave.
  • The current lane off the bridge is probably the most important single block for a bicycle facility in the City of Boston, and perhaps the Commonwealth. It is heavily used, with high conflict rates and a steep downhill off the bridge which sent cyclists flying in to a sea of cars and bad pavement. So it's the right place to start. But it's just a start. The lane really needs to be extended all the way down Mass Ave (as has been proposed here and elsewhere). 
  • By moving the bus stop to Marlborough, a few parking spaces will be lost. And the M2 will have to find a new stop (I'm not sure where). In fact, it might make sense for both bus stops to be moved to either side of the Marlborough intersection, which would make my previous plan even more feasible (expect a redraft of that in the next couple of days).
  • Still, I think that this is a huge change, because the city eliminated a lane of traffic without a months-long, drawn-out "traffic study" which would claim a reduction in LOS and that therefore a bicycle facility couldn't be accommodated. Is it reactive instead of proactive? Yes. And that needs to change. But it sets a precedent: we can remove traffic lanes in the name of safety. And it's now time to act for a safer Mass Ave, a safer Beacon Street, and safer streets all around.
