I'm glad for the Big Dig and it's decent (if far from perfect) restoration of downtown neighborhoods, but wish that it wasn't exclusively the transit aspects that got shelved, delayed, and/or cut entirely. Red-Blue connection, North-South connection, GLX... they were all there originally. If not for the "car is king" mentality of the time those essential elements wouldn't have been considered expendable. I think if it was all happening today that the political will would exist to make sure they survived. I don't know what the ultimate cost saving was, but I'm sure it is many times less than these projects are going to cost now that they've been delayed. You can only do open heart surgery on a major city once or twice a century.
The breathing room for a multi-modal solution (functioning roads, functioning transit, and functioning bike/ped connectivity) can come as MassDOT starts letting go of the notion that every time the asphalt gets cut for an improvement there must be an increase in capacity. Old habits die hard, especially when it's the laziest way to justify more pork spending. But it's undeniable that things are changing. Neighborhood preservation is paramount now. The costs of maintaining old infrastructure long past its expiration date is forcing decisions on what's essential and what's surplus-to-requirement. And there is real momentum to start retiring unnecessary, city-scarring capacity: Casey Overpass, McGrath Highway, Rutherford Ave., Bowker Overpass, the Route 79 shitshow in Fall River. With more of that to come as the ex-MDC roads continue to get reined in...trimming the fat on Fellsway, Greenough Blvd., Birmingham Pkwy., the Fresh Pond/Soldiers Field octopus. And the debate on Storrow's ultimate future probably dominating conversation for the next 20 years.
Sooner or later if they want their pork they've got to adapt and go with that momentum, not fight against it. Casey Overpass was the real bellweather there. Every scare tactic about carpocalypses being unleashed on Forest Hills if they didn't make a bigger, better overpass in its place made no impression. It isn't gaining traction on McGrath or Rutherford either. The Bowker teardown proponents started debunking it as their offensive move...not even waiting for the state to start giving the usual song-and-dance and then reacting. Traffic studies that plug in a default 5% increase per X years as if it were some mathematical constant are getting questioned for justification on where and why those volumes are programmed...where before increases were just a given and a starting point.
This is new. And it's not taking unprecedented mass revolts like the 1960's to beat back the DOT's default thinking. So I think we're seeing the beginning of an evolution. They'll resist...they'll resist as long as it's expedient. But diminishing returns aren't going to keep it expedient much longer. If they want their money to build, the planners are going to have to adapt to a post- capacity increase mentality.
And even for asphalt-only construction, it matters to take a pass on capacity-increasers when it can address highway bottlenecks that are failure points under any load or capacity. Like straightening out all those mangled half-interchanges that were never finished. Fixing minor interchanges and weaving problems. And realizing that full-size shoulders are sometimes just as important to keeping the traffic flowing resiliently as the actual travel lanes, and that claiming every ounce of space for extra operating lanes sometimes does more harm than good. Drive modernized, breakdown travel-banned 128 vs. the artificially zipper-narrowed SE Expressway when there's an accident: it's a temporary blip vs. an entire commute flushed down the drain twice a week or more. How much do you want to wager that simply removing the zipper for full left-and-right shoulders could help the Expressway un-FUBAR itself more than widening it the rest of Dorchester to extend the HOV lane?
