2 lane freeways

[ethanman62187]

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?

[agentsteel53]

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.

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.

[vdeane]

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?

[Hot Rod Hootenanny]

Is that Maine strech of 95 still 2 lanes?

No, it's been 4 lanes, with median, for, at least, 20 years now.

What is the speed limit for that?

65 right now, but it may eventually be raised to 75.

[deathtopumpkins]

The bill raising it to 75 passed, if I recall correctly.

[1995hoo]

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.

Wow it passed already?? Good for them!

[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).

[ethanman62187]

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.
