Interstate 11 project could include highway on eastern rim of valley


This artist’s rendering shows what the redesigned interchange of the Boulder City Bypass and U.S. 93 would look like at Railroad Pass. The Railroad Pass Casino is to the the left. If U.S. 93 is designated an interstate between Las Vegas and Phoenix, the bypass route would become part of the interstate, officials say.

Quote:
The Nevada Department of Transportation hasn't ruled out building a highway on the eastern rim of the valley as part of the Interstate 11 project, but planners admit it would be an expensive proposition that essentially would complete a freeway loop around Las Vegas.

"Everything is on the table," said Sondra Rosenberg, project manager for Nevada's portion of the I-11 plan, which would create a new interstate highway linking Phoenix and Las Vegas, the two largest cities in the country currently not connected with an interstate.

Rosenberg made her comments at a public meeting Thursday at which representatives of NDOT and the Arizona Department of Transportation explained the process of bringing U.S. 93 up to interstate highway standards.

Most of I-11 would be in Arizona and would likely use U.S. 93, a four-lane divided highway from Hoover Dam at the Nevada border to Kingman and a mix of two- and four-lane roads from Interstate 40 to Wickenburg.

Michael Kies, Rosenberg's Arizona counterpart with ADOT, explained that interstate highway standards would include ramps to enter and exit the highway and overpasses or underpasses at key intersections. Currently, U.S. 93 has several at-grade intersections and traffic lights on the route.

Are you trying to compare drink driving with a little bit of speeding in good conditions and on good quality roads which just happens to have strangely low speed limits?
Those same roads in most European countries would have 75-80mph limit

Interstate 10, Katy Freeway, Houston, TX

Today it's 4 years ago the massive reconstruction of the Katy Freeway in West Houston was completed.

The Beltway / Katy stack interchange probably has the highest number of through lanes in any interchange in the world (14).

Yep. Roads were closed, travel was restricted....

Actually, the Turnpike will often lower speed limits if it's very windy.

I saw a picture with a 45 mph speed limit. It looked like the Turnike, but I'm not sure if it was the turnpike though.

The Turnpike has these very distinctive reduce-speed signs that they've been using as long as I can remember (since the 70s) and that I've never seen anywhere else:

I-69 Indiana

The 67 mile segment of I-69 in southwestern Indiana will open November 19.

http://www.sfgate.com/news/science/a...19-4003856.php

This may well be the largest single freeway opening in the past 25 years.

I-15 Utah

The 24-mile CORE project wraps up by next Monday, November 5. The project added 2 lanes in both directions south of Salt Lake City. The project ran from Spanish Fork to Lehi, through the urbanized corridor around Utah Lake. Provo is the largest city in this area.

The freeway was widened from 4 to 6 lanes in Spanish Fork, 6 to 10 lanes through the Provo area and from 8 to 12 lanes north to Lehi, just south of Salt Lake County.

I'm surprised you didn't know about those! :-)

And then there's this: http://www.flickr.com/photos/mpd01605/3649509746/

Those would be at the northbound split between the two so-called "spurs"; you'd also see them at the split between the cars-only and cars-trucks-buses lanes, at the southbound split between the spurs....

I don't know how easy it is to tell from that photo what's going on, but the signs have panels in them; that's the default position. If one side is congested, or actually closed, they can change the panels to direct everyone the "good" way. In that situation, the background color on the warning panels is red.

Are the neon ones* the first VMSes in the world?

*The AARoads thread says they go back to the opening of the Turnpike in the '50s; what I've called the splits haven't existed that long - the "Western Spur" opened about 1970 - so I'm assuming the changeable-panel signs go back onlly that far.


EDIT/PS: note the beehive state highway markers in your Utah post.

MIAMI

This Is The Underbelly Of The Giant I-395 Of The Future



Quote:
This is FDOT's idea (hope, dream, pie-in-the-sky) of what it'll be like to hang out underneath the new I-395 that they have in the works. Superhighway overhead? Check. Groovy V-shaped pylons? Check. Space to create an under-highway park with elaborate landscaping and grass that magically doesn't die in the shade? Check. And this isn't even the portion underneath that giant land bridge whooshing over Biscayne Boulevard. Oh, yes, that'll be something. To read some FDOT-babble on the I-395 reconstruction project, click on through!

FDOT says:

Quote:
Project Limits From west of I-95 to the MacArthur Cswy Bridge Municipalities City of Miami Project Summary This project involves the rebuilding of the Interstate 395 (I-395) corridor from its terminus at the west of the I-95/Midtown Interchange (I-95/State Road 836/I-395) to its corridor terminus at the West Channel Bridges of US 41/MacArthur Causeway, approximately 1.4 miles. I-395 is an Interstate Principal Arterial and major east-west connector serving Miami Beach and the ports. Proposed improvements include: (1) Building new elevated ramps (one eastbound and one westbound) that will provide direct linkage between I-95 and I-395. (2) Improving roadway design including updating the alignment and upgrading the roadway surface. (3) Creating a visually appealing bridge. (4) Building vertically higher structures that will improve the visual quality of the bridge.

Anticipated Construction Start Date: January 2021
Construction Cost:$500 to 600M

I-12 Slidell, Louisiana

A couple of miles of the eastern end of I-12 were widened to six lanes. The project was completed on November 2, 2012 through the Slidell area. The $ 25.7 million project was completed in a year.

I-435 Kansas City, Kansas

I found out about this massive $ 600 million overhaul of I-435 and adjoining sections in Lenexa and Overland Park, two southern suburbs of Kansas City on the Kansas side.

I-435 will be widened substantially and the K-10 / I-35 / I-435 interchange will be reconstructed.

The plans are as follows;

* widen I-435 mainline to 2x5 lanes west of I-35
* construct a K-10 to I-35 bypass. Traffic from K-10 to I-35 never gets on I-435 mainline
* construct a basketweave west of the I-435 / US 69 interchange
* widen I-435 mainline to 2x6 lanes east of I-35
* widen K-10 to 2x3 lanes west of I-435

I-435 cross section: 18 lanes between K-10 and I-35.


I-435 cross section: 12 lanes east of I-35


overall project:

This is what it looks like today.
