Why is there a quick lane drop on westbound I-540 near the US-1 interchange?

I am guessing, but maybe because US 1 is considered a major highway and a lot more traffic coming and going from it than the through traffic that currently exists for I-540 there.

Would this need a high rise bridge to prevent flooding problems like US-17 does?

Can the Southwest bypass be called I-287 once it connects to I-42 or US-64?

Not likely as auxiliary interstate highways typically connect to the parent interstate route. I am aware I-585 is an exception, but that is only because I-85 was moved onto a new bypass route, leaving its spur.

If an exception was made, it would likely be also a odd number since since it to would be a spur from an interstate.

Keep in mind that both AASHTO and FHWA would need to sign-off on it, assuming NCDOT even submits the idea.

US 17 has a high bridge because it replaced a draw bridge.  If they were trying to alleviate flooding they would've raised the causeway too.

I mean, they idea of an auxiliary spur not touching its parent isn't unheard of. Look at I-175 and I-375 in Florida, I-795 in Maryland, I-105 in California, etc.

Now granted, tolbs is referring here to if they upgrade NC-11 on either end to interstate standards between US-64 (I-87) and US-70 (I-42), which in that case, I'd say, yes, a I-x87 could work.

NCDOT posted this on their Twitter as well, but the site seems to be down at the moment as I try to access Bob Malme's update on I-73/I-74.

NCDOT awarded a contract to improve the Mebane Oaks Road interchange on I-40/I-85 in Alamance County. Completion is scheduled for summer 2023.

Mebane Oaks Road was long overdue for this type of overhaul. Jimmy Kerr Road (Exit 150) has to be next.

Or an x42.  2 87's is 1 more than enough; don't need yet another x87 (insult to injury!).

Alamance County was not careful about getting Tanger Outlets to make improvements to the Mebane-Oaks exit when it first opened, so the current arrangement was a shoe-horn job NCDOT.  On the other hand, Orange County asked Tanger for too much when they originally proposed its development at the Jockey Lot Flea Market at the Buckhorn Road exit.

The Buckhorn Flea Market has had so many rumored developments. Growing up the biggest rumor for that land was a Six Flag style theme park was coming.

This area is going to get very busy soon with a huge medical supply distribution center being constructed close to Gravelly Hill Middle School on West Ten Road east of the Buckhorn exit.

An interesting find in the Raleigh area: The Wake/Raleigh online GIS maps show a disconnected section of E Tryon Rd, adjacent to I-40 south of the I-40/I-87 split, right after the Rock Quarry Rd overpass (the one without an exit).



It lines up with the dead end of Sunnybrook Rd on the other side of I-40, so it appears it was intended to meet up one day.  I did some research and found a 1994 feasibility study: https://connect.ncdot.gov/projects/planning/FeasibilityStudiesDocuments/U-3111_Feasibility-Study_Report_1994.pdf

The funniest part of the study: "A grade separation is recommended at the proposed crossing with I-40".  hahaha!!! Ya think?!?  You don't think a 4-way intersection on an interstate will be sufficient??

What should the DOT do about this... No barrier, no guardrails. A person can swerve into the exit lane.

And the stripping looks odd aswell.

Oddly, the bridge has a concrete median strip on it.  Curious why that wasn't a feature all the way through the interchange.

Given the age of the bridge, the best solution IMO is when it is replaced to make room for a formal jersey barrier that is along the entire C/D setup.

The DC Beltway has an interchange like this in Prince Georges County - C/D lanes (plus the right through lane!) with no real barrier.

I-95 at Exit 109 in Maryland at least has a small raised concrete curb (though can easily be driven over).

Given how that's signed with 'lanes divide' and 'all lanes through' that seems like more of a local/express divide.  That encourages the use of the local lanes by traffic staying on the highway.  C/D setups usually are more for only exiting or entering traffic.

A K-rail or thrie-beam barrier between the through and C/D lanes might well be part of any upgrades to Interstate status when NCDOT elects to undertake that.  Question: are the C/D lanes on I-95 on the lower interchange level configured the same or do they feature some sort of barrier?

There is a median between the lanes.

I-95 is correctly done with a grass median between the mainline and the C/D roadway.

Good to know (and see!).  Obviously, the same isn't feasible for US 64; a physical barrier of some sort would be necessary.  Again, something that would likely occur during a Interstate upgrade.

They plan to add a concrete barrier, until they reconfigure the interchange.

That interchange was constructed in the late 70s. the bridges are not that bad, but I guess they could use some modification.

As far as I know, no. But I'm sure NCDOT will consider it.

This is how it should look as of right now.
