I-22, Birmingham, AL

The I-22 / I-65 interchange in Birmingham, Alabama is beginning to take shape.

I-22 was pretty much finished 5 years ago, just the interchange with I-65 was missing. What was the issue here? land acquisition?

it was reported a few months ago by Chriszwolle that the contractor messed some measurement up with one of the bridges, and the project was delayed about a year I think.

Details Emerge for $1B, GDOT-Orchestrated Traffic Jam



Quote:
The Georgia Department of Transportation has announced that the largest project in Georgia highway history will kick off sometime in late 2016, according to a report by the Northside Neighbor. Estimated to cost just shy of $1 billion, GDOT expects the revamp of the Interstate 285/Ga. Highway 400 interchange to take about three long, long years. Not confined to the immediate vicinity of the interchange in Sandy Springs, work will stretch along more than four miles of I-285 and more than a mile of Ga. 400. The project promises some relief from the persistent traffic woes of the area by first causing a three-year-long traffic jam. That prolonged headache could make whatever happens in the end seem downright joyous. For a little while, at least.

There are a few changes since we last visited this project a few months ago. The biggest is to the north at 400 and Abernathy Road. Since the project was first proposed in the late '90's, that interchange had been a SPUI, but the latest iteration changes it to a DDI, The GDOT people (I attended the public meeting) said that the DDI led to better traffic flow. Here's a photo-- north is to the right:




The loop ramp is existing and will be removed. If you look closely, you can see that the 400 southbound to Abernathy westbound movement is three lanes, but the return movement is only one. WTF?

Back on the 285 part, a point was made that except for the ones over Lake Forrest Drive, the bridges carrying I-285 will remain in their currect configuration, not even widened in situ (though decks will be replaced).

Sorry for the blurry photo-- I drank a Mountain Dew before the meeting, and my hands may have been vibrating.

Widening I-5 in Portland

Portland Oregon traffic suffers a severe bottleneck as I-5 narrows from 2x3 to 2x2 for a few miles between I-405 and I-84. In late 2012, first the Portland City Council and then the Oregon Transportation Commission unanimously approved a plan to widen I-5 to 2x3 plus a hard shoulder wide enough to be used as an emergency lane and to rebuild the one set of exits and entrances between I-405 and I-84. The plan is called the I-5 Broadway/Weidler Plan, named after the streets which interconnect.

Funding had been held up by the much more expensive Columbia River Crossing project, which has since been cancelled. I have not been able to find any information newer than this article: http://www.oregonlive.com/portland/i..._headline.html

Does anyone have any more recent information about the state of this project?

Might I recommend you post this on the AARoads Northwest Regional board although you'll need to sign-up to become a member there. The AARoads Forum is more U.S.-centric while there's certainly more of an international flavor here.

It certainly does. I used to get 26 mph on highway on my Accord driving around 75-80mph. It started making sound above 65 so I drove in the 60-65 mph range. I got 33 mpg (identical driving conditions).

You don't even need empirical evidence. This is basic physics - drag goes up by square.

drag goes up by square, but the engine efficiency goes up with higher load

Example driving at 60 MPH is much more economical than 20 MPH, the increase of efficiency is more than the increase in energy consumption

But the two curves probably cross typically around 45 mph unless the car is very aerodynamic or has a very large engine...

Lower speed limits don't have that much effect on fuel efficiency, unless it is very strictly enforced. A key point is that the lower speed limit is not followed by drivers. They lowered the speed limits in Dallas and Houston within a 50 mile radius, but fuel consumption did not materially reduce because the lower speed limits were ignored. The average speed went down by 2 mph.

Turquoise.

And it's not that bad actually, Miami can pull it off.

I'm not sure which photo you're referring to when you say you're not sure if it's an Interstate Highway. I used Google street view and determined that the first photo was taken while on Florida State Road 836 (map) approaching Interstate 395. The second photo was on Interstate 395 (map) east of I-95.

Is I-70 in Utah still a black hole in terms of cell phone signal availability?

What about this one
No Services on Interstate 70 for the next 106 miles (170 km) with this blue roadside sign located at Green River, Utah. by RaymondYu, on Flickr

I'm pretty sure services indicates rest areas, gas stations etc and not cell phone signal.
