2 lane freeways

[vdeane]

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

I thought that distinction belonged to Louisiana (parts are east of the Mississippi).

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.

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.

The speed limit would have to be a lot more than a mere 85 miles an hour for that!

Sorry, couldn't resist.

eh, cops don't care if you're doing 3 over...

[ethanman62187]

What will happen if you drive 20 MPH over limit on the passing side of this?

[ethanman62187]

I 70 in Wheeling, WV at the tunnel is constructed like this for several thousand feet.

That "wooosh" is the sound of the Back to the Future jokes going over your head.

Don't bother replying to the idiot.

It's barely a few hundred. The moment the off-ramp departs, an on-ramp joins to make it four lanes (two each through the tunnels).

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.

[ethanman62187]

Now, rural interstates with low traffic counts will have higher speed limits.

If you're going to talk about 4 lane undivided freeways, I'm going to open a new topic about that.

[ethanman62187]

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.

Portions of the Autoroute system in Quebec are also two-lane freeways (the recent A-50
extensions and A-55 come to mind).

A-20 in Rimouski is one of them.

I don't know about that, but ok.

[ethanman62187]

Well, this is undivided. I'm going to open a new topic on 2 lane divided freeways.

[deathtopumpkins]

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.

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!

I've heard of that, but never saw pictures.  I always assumed it was an undivided super-2.
