^ Except for Detroit (where I'd argue the congestion isn't in the city proper but in the suburbs), those aren't exactly large metropolitan areas.

Well, the thread is about rural freeways and we were responding to a particular comment.

The one thing that I have noticed is that the more lanes built just attracts more traffic.  I have witnessed this in Florida, Georgia, and Tennessee.  So why bother in the first place.

The cars aren't being added; while traffic increases on that route, it decreases on other routes.

Vehicle registrations have gone up by 72 million since 1990. Where are those cars going? You could easily say the owners use transit, or bike, or whatever. But we don't really build the infrastructure for those things, so most of those cars are probably being driven at least once a week.

It goes up over time due to population growth, but building a new road doesn't have much effect on the total number of cars compared to doing nothing.

A few people will be driving when they wouldn't have driven otherwise, but there are also people who are now taking a shorter route because the new road exists.

Sure. But that's why congestion has increased so much over the last 30+ years. Our roads are handling more cars than they were intended to. To alleviate the issue, we widen our roads. But in doing so, we increase the theoretical capacity of those roads. This improves the average LOS conditions in the mean time, but also makes the routes more attractive for people who live in the area that either don't, or will soon be, driving. Never mind new homeowners.

I would say most of I-81, especially from the southern terminus to I-78 in PA, and then I-78 to Syracuse being a longer term vision.

Try Duluth, MN, Binghamton, NY and I'd even argue Detroit, MI.  Despite the highways, congestion has not filled capacity.

The blanket idea that more lanes just fill up automatically with congestion just because they're there is unfounded in reality.
That's because Detroit's freeway system was built for a city much bigger than Detroit even at it's peak population of 1,849,568 in 1950. Detroit lacks a good mass transit system so depending on your car is how you get around.

For the Deep South in AL and MS, some of my thoughts:

Mississippi

I-10: Warrants 6 lanes across the state (it's not a very long stretch). Quite urbanized too between New Orleans and Mobile/Pensacola.

I-20 and 20/59: May be warranted in the longer term from Vicksburg to the Jackson metro. Apart from in Meridian, traffic isn't very high from Jackson to Tuscaloosa.

I-22: 4 lanes is definitely sufficient.

I-55: Not much in the way of upgrades needed. May warrant 6 lanes south to Senatobia in the longer term. Traffic drops quite fast once outside the Jackson metro.

I-59: 4 lanes is probably sufficient. The only fairly busy sections are near Hattiesburg but a US 49 freeway is definitely of higher priority.

Alabama

I-10: Warrants at least 6 lanes across the state, if it isn't already (it's mostly urban anyway).

I-20 and 20/59: From Tuscaloosa eastward, the sections that are not 6 lanes ideally should be. AADT is near or over 40,000 through most of the state.

I-22: 4 lanes is definitely sufficient.

I-59: I'd say it should be 6 lanes about as far as Argo. Traffic does drop into St. Clair County, and is quite low beyond Gadsden.

I-65: From the Tennessee line to near the Lowndes-Montgomery county line definitely calls for 6 lanes on any sections that are not such (especially between Birmingham and Montgomery where AADT is up close to 50,000). In southern Alabama, the AADT in the 20,000 to 25,000 range doesn't really call for it until Mobile County.

Quote from: RoadMaster09
I-10: Warrants 6 lanes across the state (it's not a very long stretch). Quite urbanized too between New Orleans and Mobile/Pensacola.

6 lanes would be a "nice to have" on I-10, but it isn't an outright necessity.  Traffic moves fairly well in part because it is INLAND from most of the coastal urbanization.  MDOT has also 6-laned it from the Long Beach exit (Exit 28) to MS 609 and is in the process of extending that to MS 57.  That covers the bulk of the busier traffic area.  I could eventually see an extension of that to Diamondhead (Exit 16) but it's not outright needed beyond Bay St Louis.  Widening across the Pascagoula River would also be very difficult due to the wetlands and the length of the bridge.  At 4 miles, it's almost as long as the Twin Spans over Lake Pontchartrain (which required emergency Katrina-related funding in order to replace and widen).

Having been stationed in that area twice, I would also say that 10 is most definitely not urbanized between Slidell and the Canal Rd exit (Exit 31) in Gulfport, especially where it crosses the Stennis Space Center buffer zone.  There's also an expanse east of Ocean Springs that is not urbanized due to the Pascagoula River basin and an adjacent wildlife refuge area.

Believe you are referring to I-81 North.  Is there really much through truck and other traffic north of Binghamton??  Would suspect it falls off quite a bit, and may have been a part, a very small part, of the decision to scrap 81's route through Syracuse itself.  That and of course the state is stretched very thin and costs there are very high.

Not now, which is why I mentioned it as something long-term, not an immediate need.

I-215 in California comes to mind mostly because the rural parts are largely being absorbed as suburban outgrowth.  I was really surprised I-215 south of Cajon Pass was still only four lanes when I drove it yesterday.

Wisconsin:
I-39/90: (Under const currently) IL State Line to US 12/18 Madison
This has been needed for a long time, thank god it's finally happening.
I-39: I-90/94/Wis 78 Portage to US 51 Portage
Why do this section but not anything north of it? I-39 between Cascade Interchange and Plover does not need 6 lanes, and won't for a long time.
I-39: Wis 54 Plover to US 10 West Exit 165 (Stevens Point)
Not immediately, but probably in 5-10 years.
I-39/US 51: Business US 51 Rothschild to Hwy WW Brokaw (Wausau)
The WI-29 concurrency is already 6 lanes, and the last section before WW has climbing lanes for trucks. The whole thing does need 6 lanes though.
I-90/94: Wis 78 Portage to I-90/94 Split Tomah.
Yes.
I-90: MM State Line to Wis 16 La Crosse (not sure if this is 6 lanes already)
The last time I was in La Crosse was 6 or 7 years ago, so I'm not sure.
I-94: Wis 25 Menomonie to US 53 Eau Claire
Not so much as between Portage and Tomah, but still needs 6 lanes.
I-94: I-39/90/Wis 30 Madison to Hwy N Cottage Grove
Already 6 lanes.
I-94: Wis 67 Oconomowoc to Wis 16 Waukesha
Agreed.
US 61/151: IA State Line to US 61 North Dickeyville
Maybe a third lane NB for slow trucks, but it doesn't need 6 full lanes.
Wis 172: I-41 Ashwaubenon to I-43 Bellevue (Green Bay)
Already 6.

Partially so.  The part from Webster to I-43 is 4 lanes.

I suppose we should just downsize all freeways in the country, urban or rural to 4-lanes. Tell me how it works it for you then  :wave:

It may seem like a 6-lane freeway is overcrowded, make it 4-lanes, and you get nowhere.

Your comment is moot. Aren't you the anti-new-freeways person anyway?
