Some freeways in the world is where nobody uses. Are 2 lane freeways allowed to be there to replace the full freeway. Interchanges MUST be built. What's the speed limit? Is passing safe?
for a while, the interstate standard allowed two-laners like this in very rural areas with low traffic counts. I-95 in northern Maine comes to mind, as does I-70 across San Rafael Swell in Utah.

Hey, in Franconia notch, nh, I93 is a 2 lane freeway with a speed limit of 45 mph.
Several of Nova Scotia's 100-series routes are of that sort. Some have interchanges, some don't (e.g., on NS-103 heading east from Yarmouth towards Shelburne and Liverpool, some of the crossroads have "exit" numbers even though they're not interchanges, whereas NS-101 has some interchanges on some of the two-lane portions). The speed limit on those is generally 100 and passing is usually perfectly safe.
The approaches to the Key Bridge on the Baltimore Beltway were two-lane roads for many years.
The current VA 262 freeway from US 250 southeast to US 11 is 2-laned. No divided segments at the several interchanges the way US 1 south of Raleigh was for many years.
The US 58 freeway bypass of Franklin started out this way, too.

http://en.wikipedia.org/wiki/Two-lane_expressway
US-36 between I believe Hiawatha and Wathena Kansas is a 2-lane freeway. Full exits for some stretches. The other carriage way is 'ready to go' whenever they want to grade and pave it.
US 220 between BUS US 220 and BUS US 30 in Bedford has passing zones and a 55 MPH limit, and at the other end of 220's path through Pennsylvania, the Towanda Bypass has passing zones, a 55 MPH limit, and full interchanges.
US 15's expressway sections from Williamsport north were like this before finally being upgraded to four lanes in anticipation of I-99.

Portions of the Autoroute system in Quebec are also two-lane freeways (the recent A-50 extensions and A-55 come to mind).
Bethpage Parkway In Nassau County Is a Super-2 With 4 Interchanges (Exits B1 - B4) and Ends at a Traffic Circle (Unsigned Exit B5) at the entrance of Bethpage State Park.
Well, there are 4 lane undivided freeways, too. An example of this is highway 27 north of highway 401 in Ontario is one.

That's not a freeway.
Sure looks like a freeway to me, south of ON 409.
There are 4 lane undivided highways. 4 lane freeways have access control and some sort of divider,even though there may be no shoulders.
There is the 2 lane Chickasaw(sp?) Turnpike in Oklahoma. It is 2 lanes full acess control toll and as I recall connects at each end to a 4 lane divided. I think it carries 2500 vpd.
Is that Maine strech of 95 still 2 lanes?

65 right now, but it may eventually be raised to 75.
The bill raising it to 75 passed, if I recall correctly.

It did, but it doesn't take effect until 90 days after the legislature adjourned (and I don't know when that was), and like many states' laws it doesn't
require a 75-mph speed limit on that road, it merely
allows such a limit.

And thus Maine becomes the first state east of the Mississippi to allow 75mph speed limits.

75 mph is safe on these type of roads.
There are a few undivided 2 lane roads in New Brunswick with freeway intersections. Speed limits are 110 km/h if I remember correctly.

I don't really think of Louisiana as east of the Mississippi since most of it is to the west.
Much of I-20 between Jackson and Vicksburg, MS was initially constructed as a two-lane freeway with four-lanes at the interchanges. I suspect such staged construction was common early in the interstate era.

I don't really think of Louisiana as east of the Mississippi since most of it is to the west.
However, both of the largest cities (Baton Rouge and New Orleans) are either completely east of the river or mostly east of the river.
deanej/Brandon: either way, the Interstate segment in Louisiana that's 75 MPH is west of the Mississippi.
In the future, 80 or 85 MPH limits will be on these type of roads.

Well, most of this is not tolled. An example of a tolled 2 lane freeway is the Chickasaw Turnpike. Another is Loop 49 in Tyler, TX.
Now, rural interstates with low traffic counts will have higher speed limits.
Now, ethanman will go to school and learn to make legible posts.

I don't know about that, but ok.
Well, this is undivided. I'm going to open a new topic on 2 lane divided freeways.
I think this topic is plenty sufficient to cover any future discussion on that subject. In the future, please split topics off like this only if there is actual discussion heading that way.
As the title of this thread is "2 lane freeways", divided ones would be just as on-topic as the undivided kind. (And, just for the heck of it, I'd throw in multilane undivided freeways too.)
Are there any examples of two lane divided (one lane each direction) freeways? I'm thinking a minimum length of one mile might be required for it to really count as a freeway, and not just a couple of ramps. Columbus's International Gateway might count, depending on one's interpretation of various factors – but that would be a stretch at best, considering that only half of the mile that can be considered a freeway is only one lane each way.
Quote from: vtk on October 05, 2011, 02:01:48 AM

I-93 through Franconia Notch.
The FL 407 is a two lane freeway south of I-95. It used to be all the way, but the City of Titusville added a side road into an industrial park. So now it is only south of I-95 where some motorists still think of it as a "one way" road. That is why there are several accidents that happen on it due to those going accross the center line while thinking that way.
The speed limit is 60 for most part, but at the interchanges of I-95 and FL 528 it drops down to 55. I am suprised that FDOT raised it with the safety issues involved, but a median would work. It may tick off a few drivers, but manybe that will show strangers that FL 407 is NOT FULL FREEWAY!

Nope, it's all divided here:

Here's a typical "Super 2" interchange in Nova Scotia: James River Exit 30 on TCH104. Speed Limit is 100 kmh. Full off/on access in both directions........ you have to be a bit more careful when merging as traffic can't get over to let you in.

In Nova Scotia most overpasses on the Super 2s were constructed so they could eventually be extended when the highway was twinned.
Here's West River Station Road at Salt Springs on TCH104. This section was twinned in the late "˜90s. The original structure is on the left. The square abutments were buried for about 30 years then uncovered when this section was twinned and the structure extended to the right.
(https://lh4.googleusercontent.com/-vxmKR8M--Cg/TpLXACelbtI/AAAAAAAAH6M/j9whIo-nggE/s640/IMG_0423.JPG)
West of this structure, the highway was twinned with the original carriageway becoming the new westbound lanes. East of the structure (below) a totally new divided 13 KM by-pass was constructed to Alma. In the photo you can see where the old alignment extending through the gap in the trees and joined the original Trunk 4.

To appease the business owners on the by-passed section, a "Service-Loop" was identified but as you can see on the sign, in the years since, most business have closed and the gas, food, lodging symbols have been plated over.

When you live in the DC area, as I do, you just assume people won't do that anyway!
It's been three years since I was last in Nova Scotia and the driving there was far more civilized than it is around here, though some of the roads on the eastern side of Cape Breton Island were in quite atrocious shape (and we didn't go around the southeast corner on the Fleur-de-lis Trail, which I was told is among the worst road conditions in the Maritimes).
It's Thanksgiving here too, I live in Ontario. I visited Nova Scotia for a couple of days back in 2006. I only really got to see Halifax during that time. If I get the chance to go back what I'd really like to do is drive the Cabot Trail.
Back on topic I was into Quebec a few weeks ago and they have an impressive network of two lane freeways like Nova Scotia. MTQ, Quebec's Transportation Ministry is just about to open the final leg of a new 2 lane freeway that will link Gatineau to Metro Montreal.

I think there's a few more sections left to build before A-50 is actually completed. The section that is to be opened in the next weeks ends in Fassett or Montebello.
Like Nova Scotia, the overpasses on all super-2 autoroutes in QC are designed to leave room for twinning. In fact, they don't even bury the structure.
The current super-2 autoroutes in Québec are:
- A-20 from Rimouski to Mont-Joli;
- A-30 in Salaberry-de-Valleyfield (twinning in progress; to be renumbered to A-530 next year);
- A-30 from Bécancour to Gentilly;
- A-50 except through Gatineau, Lachute, and between the Mirabel Airport and A-15;
- A-55 between A-20 and Bécancour;
- Some of A-73, perhaps some of A-70 (not yet clinched);
- A-955;
- Probably a few more 3-digits I missed.

I think that 110 KM/H should handle this 2 lane freeway.
I think the mods should handle you.
I believe the speed limit is indeed 110 on there (km/h, BTW, not "KM/H").
Not sure how Nova Scotia does it, but on the New Brunswick side, the Super-2s didn't go higher than 100km/h, at least those Super-2s I've been on (parts of NB 1 and also NB 15).

I was referring to the roads shown in ethanman's most recent post, which aren't Super-2s. The Super-2s I've driven in Nova Scotia were generally posted at 100.
I hit 140 going through the Cobequid Pass (not a Super-2, and posted at 110) and it seemed quite reasonable, but no doubt it would have been a hefty ticket had I been stopped.
Right, those are 4-lane freeways, but ethanman referred to them as 2-lane. 110km/h in those 4-lane cases makes perfect sensee...same speed limit New Brunswick generally uses on the 4-lane parts of NB 1 and NB 2.

Someone was caught last weekend on the Cobequid Pass doing 172.......It's an automatic seven-day licence suspension with the vehicle impounded also for seven days. Then there's two fines — one for stunting with a fine of $2,410.21 and a loss of six points and one for speeding with a fine of $282.71, three points and a further seven-day licence suspension.
Stunting is 50km/h over the limit........I'll be heading over the Pass in about an hour on my way to New Brunswick but it won't be at that speed!
QuoteWould MD-90, the Ocean City Expressway qualify?
Most of it, yes. There's a traffic signal on the Isle of Wight, so that's the end of the freeway, but west of there to US 50 is 2-lane freeway. From just west of the St. Martin River to just east of US 113 is even 2-lane divided freeway.
