Last freeway in your city to be widened

[froggie]

MSP sucks at widening. The most recent large-scale widening completed was 494 between MN 55 and 94/694, in 2016. Some freeways like US 169 and MN 62 have yet to receive any major widening work.

That may be the most recent *completed* one....  parts of I-35W are being widened (from 9 lanes to 10) as we speak.

More like 8.2 to 10.  Once it's finished, the HO/T lanes will be open 24/7.  The previous northbound shoulder lane was only open during the morning rush.

Last freeway in NW Indiana to get a widening project would be Interstate 65 between U.S. 30 and IN SR 2 (completed in 2018)

In Indianapolis, it would have to be Interstate 69 between SR 37 to SR 38 (which is being extened up north of Exit 219 to Exit 226)...
next areas that will get the expansion will be Interstate 465 in the NE & SW side of Indianapolis...

The first interstate in Knoxville, TN to be widened was "Malfunction Junction" where I-40 and I-75 split at the center of town.  The most recent widening, in 2014, was the I-40/I-140 interchange at mile marker 376.

I don't live in a city, a couple recent ones in NJ:
The Garden State Parkway has (almost?) completed the Exit 30 to 80 widening to three lanes in each direction this year.
The Atlantic City Expressway's widening to three lanes in each direction lasted from 2005 to 2014. It encompasses the eastern 31 miles (of 44 total) of the roadway.
The New Jersey Turnpike widening to 6 lane in each direction between Exits 6 and 9 (from 3 lanes for most of that distance) was also completed in 2014.
Finally, I-295 is in the process of being "widened" (actually put on a new alignment) from 2 to 3 lanes in each through the I-76/NJ 42 interchange(s).

Only limited-access road in the Albany area to be widened in my lifetime is I-87 (Thruway) between Exits 23 and 24 (I-787 to I-90). Hell, that's one of the few limited-access segments in NY to be widened period (minus short auxiliary lanes between interchanges) in the 24 years I've been alive.

Don't know how I forgot about that one. I've even driven it, both in person, and on street view.
Technically, the widening isn't "through" an interchange, but it's long enough of a segment that it certainly can't be considered an auxiliary lane, so it can count.

How long are we going to have things be to get exempted from the "through an interchange" rule?  If 4 miles is allowed, I-90 between exits 44 and 45 could count for Rochester.

Long Island, NY
Either conversion of NY-27 to limited access highway with service roads in Suffolk county or I-495 HOV lane addition , both completed in the 90s. Can't think of anything else since. Long Island has a major ROW issue so what we got is pretty much what we're goong to have.

My criteria is that if the lane independently opens/closes (especially on the left, like both Thruway examples), then it counts. If it enters/exits then it can't count, as it is not intended for use by through traffic.

Obviously, if a lane enters/exits but still continues through one or more interchanges, it can count. Like the left lane on I-390 SB, which enters at I-490 and exits at I-590. Since it is a general purpose travel lane through exits 19-16, it counts. Not that it is actually a contender, but you get the idea.

Pretty much every major freeway in Seattle has been widened over the last few years.

Interstate 5: currently being widened in Tacoma

I swear this has been going on for decades and will go on for several more

I-87 between exits 23 and 24 is an oddball in that respect.  In both directions, the lane enters as a continuation of a ramp lane, but then ends normally on the right just past the next interchange.

[Finrod]

Interpreting this as "metro area" rather than "city proper", I believe Atlanta's answer would be I-85 in north Gwinnett County, up past GA 20, just beating out the long-awaited widening of GA 400 in the Cumming area a few months earlier.

What about I-20, west of downtown?  Oh wait, last freeway to be widened, not the only one in the entire city that still hasn't been touched in more than 2 decades.  My bad.

Boston is good with widening, all interstates are at least six lanes. You have to get quite far from the city to see 4 lanes on interstates.

That's one reason why one needs to word their posts more carefully.  It would've been more accurate if you used either Boston Area or Greater Boston Area rather than just the city name alone.

Anyway, those 6+ lane Interstates outside of the city you were alluding to were either built as such from their inception or were widened at least 40+ years ago.  The most recent widening of an existing 4-lane Interstate in the Greater Boston area I can recall was the mid-70s widening of I-95 from Topsfield to Newburyport; to its current 8 lanes.  If you included non-Interstate expressways; the US 3 widening from Burlington to the NH border from the 2000s would be the most recent 4-to-6 lane conversion.

What's the closest 4 lane interstate to Boston, not counting downtown Boston?

Looks like I-89 or I-91 depending on your flavor of the day

When does I-90 become 4 lanes?

[kphoger]

When does I-90 become 4 lanes?

July, 2021

[Roadgeekteen]

When does I-90 become 4 lanes?

July, 2021

Where does it? I know it is six lanes at least until I-84.

There are several that are closer, including I-195 near the Cape (it goes to 4 lanes east of New Bedford), I-293 in Manchester, I-395, I-190, and I-93 in and north of Derry, NH (currently the closest until the widening project is completed).

Actually, I-495 from Raynham to Wareham (MA 24 to I-195/MA 25) is closer to Boston than I-190 or I-395 and since this part of the discussion was focused on where the closest 4-lane Interstates within MA from Boston are; NH examples like I-93 & I-293 wouldn't be the answer that Roadgeekteen is looking for. 

[froggie]

^ I didn't see the focus as being Massachusetts-specific (especially since southern New Hampshire is part of the "Greater Boston" area), but I had forgotten about I-495 past Raynham.  In my defense, I'm usually on 24 there and not 495...😊

Around Denver, I believe the last freeway widening project to finish was E-470, which was expanded from four to six lanes from Parker Road to Quincy Ave.

Among CDOT-owned roads, I guess the last widening was technically southbound I-225 from Yosemite to I-25, where they added a third lane in the shoulder and removed access from the DTC Blvd on-ramp to southbound I-25. That happened in October or November of 2017. At a larger scale, it'd be adding express lanes to I-25 from US 36/I-270 to 120th Ave around 2016. It doesn't really feel like that project totally finished, though, because they almost immediately started on express lanes from 120th to E-470. Next to finish will be the C-470 express lanes (toll only) from I-25 to Wadsworth, due sometime next year.

Around Colorado Springs, the last widening was I-25 was from Woodmen Road to Hwy 105 in Monument (four to six lanes, with auxiliary lanes for Woodmen-Academy-Briargate-Interquest). Widening from Hwy 105 north to Crystal Valley Pkwy in Castle Rock in progress now; it's mostly adding HOT express lanes, but the revenue study indicates that the express restriction won't start on the south end until near County Line Road.
