Interstate 73/74

[Strider]

In the meantime, maybe the interchanges on US 220 north of Interstate 73's present terminus should be numbered (with Interstate 73 mileage-based numbers). That is, unless any of 220's existing exits are bypassed by a new alignment in the future.

That section of US 220 will not be bypassed. The plan is to upgrade the existing US 220 to interstate standards with frontage roads in some sections all the way to VA state line.

When looking at this, there used to be a proposed flyover from the Asheboro bypass to I-73 South and I-74 East. Wonder why they removed it...

The old "main exit" for Asheboro is for both US-64 and NC-49 from the west.  Traffic from Richfield and Baden Lake is typically headed up US-220 towards Greensboro.  Traditionally, most of the US-through 64 traffic from the west is headed south on US-220 (this was the main route from Ohio/West Virginia to Myrtle Beach back in the 1960s and 1970s).  Very little of the northbound traffic on either US-64 or NC-49 would head that far south on the Asheboro Bypass to get onto US-220.  The new bypass may take the through traffic off of the main drag in Asheboro, but doesn't do much to relieve congestion at the old "main exit".  Which is now numbered Exit 72A/B.

My guess would simply be because upon a further review, they deemed the volumes did not warrant a flyover for any of the loops. Given the two highways locations, I can't see much traffic switching between the two routes in any large volumes.

However, I will make an exception to this, and say that because of the Zoo access road interchange built on the bypass just east of the I-73 interchange, a flyover between I-73 South and US-64 East might have been warranted to accommodate zoo traffic from the north (likely busier than from the south). But that would strictly depend on how busy the loop gets during peak times.

They removed the flyover because of cost-saving. Instead of a flyover, they replaced it with the collector distributor lanes and the loop ramps. Also, you're right. traffic volumes did not warrant a flyover at this time.

Agreed, that whole segment of I-73/I-74 will need to be reconstructed at some point through Asheboro. Many geometrical deficiencies and overall being substandard. They reconstructed the mainline in the past decade to meet basic interstate standards and brought the speed limit up to 65 mph, but there's still much more work to do, which that feasibility study did outline some solutions.

Having been on that bypass a few times since it's opened, they definitely made the right call on cutting the flyover out. The US 64 bypass is generally pretty desolate every time I use it to link to NC 49. The buffer lane they added at the cloverleaf with I-73/74 between the thru lanes and the merge / exit lane is more than adequate to safely handle people entering and exiting US 64. Given how quick cities along / near I-85 are growing it may become necessary in the future, but for now they've built more than enough to suffice for a while.

NCDOT still needs to look at that dreadful interchange design for I-73/I-85/US 421 south of Greensboro. The interchange was built with in mind that I-73 was to continue on US 220 towards I-40 and turn west. But, now that I-73 is routed northwest on the Loop, that interchange needs to be fixed. Hopefully in the next decade or sometime in the distant future.

Does it really HAVE to? It seems like it should have a flyover when a ramp carries an Interstate highway, but does it need one? There's probably not a ton of traffic that uses that direction. W-S/High Point/Charlotte and Points West traffic would've used 74, traffic to downtown Gsboro takes 220 to Bus 85, and 85 takes the bulk of the rest. It seems it would only be a bit of airport traffic, the west side of town, and Martinsville-not really a ton. Perhaps there's a statistic that proves otherwise, though.

Only about 5,500 AADT use the loop ramp, which is the highest traffic movement at that particular interchange. It's not a pressing priority for a flyover, given the lower volume, especially when compared to what some loops have to handle (much higher!), but it should eventually be constructed.

Oh, it is going to be necessary in the future even if AADT may seem low right now. I live in the city and use that road everyday. There is more traffic on I-73 than it is on I-74. FYI.

Exactly why I said in the future or in the distant future. I don't know what traffic will be like after the I-73/I-74 Rockingham bypass is finished, but eventually traffic is going to increase and that half cloverleaf will not handle the amount of traffic.

After the Rockingham Bypass is finished, the new signages will divert traffic currently taking US 1 up to US 220 North going points north.... towards the Bypass. Also, it will link the current I-73/I-74 with I-95 via I-74/Future I-74/US 74 whatever that area signs that way. That may bring good amount of traffic. Other than that, you're correct. There will not be any significant traffic increases until I-73 is complete to either interstate.

Eventually I-74 is going to bring more traffic as soon as the WSEB is complete to US 52. It will be completed in within a few years.

If I were NCDOT, I'd just find a way to identify some funds and construct I-73 more or less atop NC 38 right down to the SC state line (4 miles, give or take) -- i.e., essentially informing SC that the ball is now in their court!  While it is technically possible for NB I-95 traffic to simply use the I-74 corridor west to Rockingham and thence north to Greensboro and W-S to reach that area, it's a bit of an oblique angle, adds 30+ miles over the projected I-73 corridor along SC 38, and would be useful primarily to those folks who want to remain on an Interstate -- period!  But given the various controversies and/or funding issues endemic to the I-73 corridor in SC, its development is certainly not a given -- so any incentive provided from NC might at least provoke some renewed interest "south of the border" toward a resolution.

I agree with you. I'd extend I-73 until at least 2 miles before the state line. It is proposed to have an interchange with Ghio Rd. between I-74/US 74 and SC state line (future Exit 2). The traffic can go either west to NC 38 (which will change in SC 38 and is one of the major roads to Bennettsville and eventually US 501 towards Myrtle Beach) or east to NC 381 (another route that changes into SC 381, with meets US 15 and US 401 and eventually SC 9).

However, NCDOT prefers to wait until SCDOT does something about I-73. I don't know the status of I-73 down in SC since I last heard about the Horry County/surrounding cities settlement based on hospitality fee. However, I also heard that Sen. Graham (R-SC) requested $12 million to fund the I-73 Project as of 4 days ago. Other than that, I can't really speak for the status of I-73 in SC.

Sounds like the NC/SC dilemma has taken on an "after you, Alphonse" aspect; somehow the ice needs to be broken in decisive fashion.  $12M sounds like just enough $$ to do or continue a study; hardly enough to make a dent in a project of that magnitude.

I'm quite sure NC won't do anything about extending I-73 south of I-74 until we see a credible commitment from SC to build all of its I-73 route. So far we see nothing at all resembling that commitment.
