What new highways opened in 2012?

I would love for the northernmost segment of CA-39 that connects to CA-2 to open next year, but apparently it won't be until 2015 at the earliest.

I believe an extension of CA-52 opened earlier this year.

[Takumi]

Some more of NC 540 opened this year, as did the new Jordan Bridge on VA 337.

[Road Hog]

The final segment of TN 840 opened and is now complete all the way around south Nashville.

[Billy F 1988]

Granted nothing else distracts the project from completion, I anticipate the northern segment of the US 93 Kalispell Bypass to be done. The southern portion is already done. MDT now has to figure out how the northern segment can be done without pissing off the homeowners near the projected path of the bypass.

Not a new road really, but it is now, for the first time ever (not including the Wilson Bridge) possible to cross the District of Columbia without having to stop for traffic signals thanks to the reconstruction of the 11th Street (S.E.) Bridge and its interchange at D.C. 295/I-295.

[Quillz]

I dunno if any official list exists, but I think both I-69 and I-22 had some construction that contributed to their overall planned lengths.

The western part of the US 10 Marshfield, WI Spur freeway/expressway opened in 2012.

Also the WI 26 Watertown, WI bypass freeway.

2011 actually - I and a friend used it to bypass central San Diego on the way back from El Centro in March.

I wonder if any segments of the Route 4 freeway east of Antioch opened in the last year or two.

A whole shitload of residential streets.

Thanks to the Interstate Highway System, it is now possible to travel across the country from coast to coast without seeing anything.

Assuming 'cross' to be more than just Columbia Island, you could cross from Oxon Hill to Bladensburg. And you could use the loops at Suitland Parkway to cross from Arlington to Bladensburg

The completion of WV 9 from Charles Town to the VA/WV border.

Thanks to the Interstate Highway System, it is now possible to travel across the country from coast to coast without seeing anything.

Never heard Kuralt say it.  But I did hear Mark Robinowitz say it ad nauseum.

But let's consider what D.C. would be like without its (mostly) suburban freeway network.

Or Baltimore without the three Interstate crossings of the Patapsco River.

Or New York City without the toll bridges and toll tunnels that were built by Robert Moses and Ole Singstad. 

The NT MTA's subways would stop immediately without  the toll revenue diverted from those toll crossings.  Of course, Caro was very wrong when he claimed that the "surplus" revenue from the toll crossings could "offset" the massive operating deficits of transit in New York.

I-781 (barely)

[bassoon1986]

New extension of George Bush Turnpike south to I-20 in the Dallas area. Also another link in the Loop 49 around Tyler, TX.

March 25th, 2011.  It is part of my daily commute.

In terms of major projects, the I-495 Express Lanes (high occupancy/toll) in Virginia opened the Saturday before Thanksgiving. A spokesman for the company that built the project referred to the new lanes as a sort of "new highway within an existing Interstate highway," which is a reasonable description because the Express Lanes have separate exits and there are no access points between them and the general-purpose lanes except at the far ends.

[Dr Frankenstein]

A-30 and 530 completed.
A-50 completed.
Partial opening of A-410.

Labelle bypass on QC 117 opened this year, I think.
New QC 236 alignment through Beauharnois

Might be missing one or two in Québec.

Also,
VT 279 in Bennington.
New ON 26 alignment through Bowers Beach.

I second that!

[roadman65]

Exciting to see I-49 and I-69 open recently. I'm curious what other major highways projects opened in 2012. And what can we look forward to in 2013?

I cannot agree more with you.

[TheStranger]

I think San Ysidro's Route 905 (future I-905) deserves a mention here, now that the gap between I-805 and the future Route 125 interchange has been fully filled in.

How long does it normally take before completed highway projects show up in Google Maps or OpenStreetMap? Days? Weeks? Months?

Depends on when someone adds it.

And why does the information displayed change depending on zoom level? For example, with I-49 in Missouri, when I zoom out in either Google Maps or OpenStreetMap they show it as US-71 with non-freeway gaps, but when I zoom in it shows the gaps as closed and labels it I-49. Just puzzled by that. Though I was impressed it was in the system at all since I-49 just officially opened a week or so ago.

Rendering lag.

[okroads]

The re-routing of I-40 between I-44 & I-35 in Oklahoma City opened in 2012.

[hbelkins]

A new section of Corridor H (US 48) in West Virginia.

The William H. Natcher Parkway extension in Kentucky.

I think the Pennyrile Parkway extension also opened this year.

-US 322 bypass of Mullica Hill, NJ
-US 202 parkway in Doylestown, PA

[Alps]

Triangle Expressway Phase 3 is now open in NC.
