I-45, Dallas, TX

A segment of the US 175 (Wright Freeway) in Dallas will be demolished. The US 175 (Hawn Freeway) will be extended to I-45 and I-45 will be widened to eight through lanes to accommodate the additional traffic. The Wright Freeway will be turned into a six lane urban arterial. It is probably the first freeway removal in Texas.

map:


The Wright Freeway is actually the former routing of the pre-Interstate US 75 freeway from Dallas to Houston. It was built in the mid-1950s and opened to traffic in 1956. Modern I-45 was built on a new alignment, resulting in two parallel freeways and a nasty curve to follow US 175.

At this location, US 175 actually carries more traffic (85,000 vpd) than I-45 (70,000 vpd). The combined volume is 155,000 vpd, which is relatively high for eight lanes, but the six lane arterial will continue to carry some of that traffic, and southern Dallas is not as booming as north of the city.

The nasty turn where the US 175 C.F. Hawn Freeway becomes the S.M. Wright Freeway. US 175 will be extended west from here, to I-45.

From time to time there will be an accident where a car can't make the curve and bounces off the wall and back into the neighborhood to the northeast. That's why it's known as "Dead man's curve".

I-10, Texas

One of the at-grade intersections along Interstate 10 in West Texas. This is west of Van Horn.

I didn't know interstates ever had at-grade intersections! Is this an exception to the "limited access" rule?

I guess that far out in the middle of nowhere there's so little happening that they figure that it won't matter. But of equal concern is the far right. Is that a railroad paralleling the tracks so closely? Not sure if that's within the safety standards.

I guess that here they just took the existing country road and doubled it. They did that in other places too.

There are few more on I-40 in Texas I believe.

And Montana

basically wide open spaces that really can't justify full grade separation

I was just there 2 weeks ago!

The pointy mountain to the right is near Sierra Blanca, where there is an internal border checkpoint you have to stop at when going east. It makes sense considering that past that point you can actually see the Rio Grande and Mexican villages on the other side. So this grade crossing isn't the only possible interruption to the limited access nature of this road.

That road might go to, like, 1 ranch. You can drive for miles out tthere and see nothing except for a tiny grove of trees someone planted around a house. Its unbelievable how much land a single family might own, you could build an entire city on some of those ranches. Who knows how many of the numerous border patrol vehicles hauling atv's you see on the road turn onto it though.

Does the relocation of I-30 south by one block through downtown Fort Worth count? I guess that wasn't really removing an entire route but rather straightening and refining its path. Sort of like what was done in Oklahoma City or Providence.

It's not a railroad, it's a road

Is this the 2nd same number Interstate/US Highway concurrency after Interstate 74/US 74 in North Carolina?

Speaking of Interstate 74, I don't understand what's going on with Interstate 73/74? It seems like a project that will never finish, kinda like Interstate 69. They don't build Interstates fast like they used to. The U.S. doesn't seem to build any transport infrastructure fast unless it's a Texas tollway.

Texas seems pretty adamant about constructing I-69, but funding is tight. And Tennessee and Kentucky are also progressing I-69, as is Indiana. I don't see the Arkansas section constructed anytime soon though. It has little value for Arkansas and I'd say I-49 is more important than I-69 for them. And Texas - Memphis is almost as fast with I-30/40 as it would be with I-69.

Interstate 69 in East Texas seems to be well justified, there is already a proven amount of traffic even with US 59 not being a national corridor yet. There are sizable communities, such as Lufkin and Nacogdoches which are probably the largest cities in Texas with no freeways at all.

States build Interstates, not the federal gov't. Hence the disparities.

North Carolina seems to be gung-ho about building out I-73/74.
Virginia is slow about 73, though a route has been more or less identified. 74 would multiplex with 77 to WV.
Speaking of WV, and for that matter Ohio, they don't seem to care much about a 73 or 74 extension.

If 73/74 doesn't end up actually happening north of VA, I think NC should just renumber them both. 74 could be either 42 or 30something, and unless they do build out 73 in SC, they can just build it as an extension of 581 from Roanoke and truncate the route at 40.

I-10 / I-45, Houston, TX

The freeway that ends all freeways. This is a cross-section of the I-10/I-45 interchange northwest of Downtown Houston. It will feature 28 lanes.



It is part of a very large project to reconstruct the Downtown freeway system. It is planned to demolish the elevated section of I-45 along the south side of downtown. I-45 traffic will be redirected along I-69 and I-10 east and north of downtown.

To accommodate that new flow of traffic around downtown, the elevated eight-lane stretch of I-69 along the eastern side of downtown will be replaced by an 18-lane below-grade freeway. I-10 along the north side of downtown will be realigned and widened from 6 to 18 lanes.

In addition, I-45 (North Freeway) will be widened to 12 lanes, including 2 managed lanes each way. The below-grade segment of I-69/SH 288 south of downtown will be widened from 16 to 20 lanes.

It's a *h.u.g.e.* project.

You can find the schematics here: http://www.ih45northandmore.com/scoping_documents4.aspx

Nothing undertaken in Texas is ever not "h.u.g.e". It seems the freeway system in Houston will forever be under construction under we have flying cars.

Hmm it seems the 401 may finally be overtaken by this project, certainly on the widest highway title.

I-5 approaching Seattle

I don't know why I haven't posted here before, but I guess it's better later than never. Prepare for tons of pictures from Seattle's freeway overpasses (with some bonuses).

The first batch, I-5 approaching the Seattle CBD from the south. A block-wide trench with two "tunnels" (which are actually lids holding up a park and a convention center) that elevates above street level at both ends, this section of freeway carries a daily average of 205,000 vehicles and is 14 lanes at its widest point.

There's plenty of streets that cross over I-5 in downtown, thanks to the trench design, only requiring an uphill walk to the freeway from the core of downtown.

Starting from Holgate Street in SODO and ending at Yesler Way in Pioneer Square (pictures taken from April 2014 to February 2015 with my recently-retired point-and-shoot camera):


I-5 northbound from Holgate Street by SounderBruce, on Flickr


I-5 southbound from Holgate Street by SounderBruce, on Flickr


Downtown Seattle from 12th Avenue Bridge by SounderBruce, on Flickr

I-5 north from Yesler Way by SounderBruce, on Flickr


I-5 south from Yesler Way by SounderBruce, on Flickr


I-5 northbound from Yesler Way by SounderBruce, on Flickr


I-5 southbound from Yesler Way by SounderBruce, on Flickr

Stay tuned for Part 2: the I-5 trench in Downtown.
