Is it though? I'll believe it when I see it.

Yes the I-93 and I-95 clover-leaf in Woburn simply isn't designed for the number of vehicles... I wonder if it ever really was. Extra lanes could help, but the real issue is that the interchange needs to finally get redone with at least some flyovers ... there isn't much room to work with residential neighborhoods on 3 sides...

Lack of appetite for eminent domain (of possibly 5, 10, 20 or maybe even 30 yards and houses depending how you do it) is part of what has held up that project for decades and trying to do that project in-place with multiple temporary ramp closures and lane reductions...

It will happen eventually, but probably only when the I93 overpass is ready to fall down... which doesn't look that far off by the looks of it.

Yah wasn't the green line extension supposed to be opening around now.

The 93/95 interchange in Woburn is flat out awful. Massachusetts seems to be one of the only states where you can have the interchange of 2 major highways and no additional roadway capacity to facilitate the interchange.

Example - 95 should widen to 4 full travel lanes plus to 2 additional travel lanes a mile before the interchange - those 2 additional lanes would be exit only. On the other side you would have 1-2 full travel lanes for those merging from 93 that would last for a mile.

The way to fix the I-93 / I-95 interchange is a very high flyover, with directional cross-over ramps under it. High flyover for through lanes of I-93 (plenty of space up there, and the road is straight enough you can start and end well before/after the interchange). Crossover ramps under the flyover to eliminate the clover-loops.

Yes, design wise this is a solved problem... as they say. And it really shouldn't even be that expensive compared to the benefits. Just haven't had a state government able to actually get it done in at least the last 40 years.
