My prediction on the numbers for the two new North Carolina Interstate Corridors

Could these be the next two Interstates in North Carolina?

It seems more than likely that NCDOT is going to petition AASHTO to approve the formal numeric numeration for the two new interstate corridors that were included in the FAST ACT. The two corridors are US 64 from Raleigh to Williamston then continuing north on US 17 to Hampton, VA. The other follows US 70 from Interstate 40 near Clayton eastwards to Morehead City.

NCDOT is most likely going to submit an application for both routes this April for the AASHTO meeting this coming May. Here are my predictions for the number of each route.

US 70 Corridor - We know that NCDOT is planning to petition for a number between 40 and 60. Obviously, 40 is already taken, and there is an Interstate 44 already in place running from St. Louis to Wichita Falls, TX. 42 is possible - however - there are a few of the opinion that since NC 42 intersects with the proposed Interstate this number is out. Though, this hasn't stopped NC 73 from intersecting with I-73, I think NCDOT will pass on 42 because of NC 42's close proximity. My guess is Interstate 46. NC 46 runs near the state line and can be renumbered if the state chooses. AASHTO and or the FHWA may throw a curveball and suggest a three digit branch of Interstate 40. If that is the case, and because I am going to hedge by bet here - I'll say that this suggestion with be Interstate 340 because the connection to 40 lies between 140 in Wilmington and 540 in Raleigh.

US 64/US 17 Corridor - This is slightly more difficult. The local business coalition that pushed for an Interstate designation along this corridor has always branded this as Interstate 44. However, they concede that Interstate 44 may not be the right number for the route. There seems to be an overall consensus of opinion for Interstate 50. Plus, the western end of this corridor - from I-95 in Rocky Mount west to I-440 in Raleigh - already has an Interstate designation, Interstate 495. So what will NCDOT do? Scratch 495 and have a two digit number for the entire corridor? Keep 495 and begin the new route at Interstate 95 in Rocky Mount?

My guess - Interstate 50. Yes, US 50 goes through Virginia but it is nowhere in the vicinity of the Tidewater Region. If that is of a concern - Interstate 54 would be my next choice. I also believe that if a two digit Interstate is approved that the allowed signage for the new route will go beyond Interstate 495's current end at I-540 in Knightdale. They will allow the route to be signed to the US 64 Business Exit in Wendell (Exit 429).

Of course, I'm most likely wrong. Feel free to make your own predictions in the comments below.

Chowchilla Mountain Road to Yosemite National Park

Chowchilla Mountain Road of Mariposa County is one of the oldest roadways servicing Yosemite National Park. As presently configured this fourteen-mile highway begins at California State Route 49 near Elliot Corner and terminates at the Wawona Road in Yosemite National Park. Chowchilla Mountain Road was constructed as a franchise toll road over Battalion Pass circa 1869-1870. The highway was built at behest of Galen Clark to connect the town of Mariposa to his property near the South Fork Merced River at what is now Wawona. In late 1874 the highway along with Clark’s Station would be purchased by the Washburn Brothers. The Washburn Brothers would continue to toll Chowchilla Mountain Road as part of their Yosemite Stage Route lines. The highway would ultimately become a Mariposa County public highway in 1917. Mariposa would later be more directly linked with Yosemite Valley in 1926 following the completion of the Yosemite All-Year Highwa...

Angus L. Macdonald Bridge

At 1.3 kilometers (or about 0.84 miles) in length, the Angus L. Macdonald Bridge is one of two bridges crossing over the Halifax Harbour between Halifax, Nova Scotia and Dartmouth, Nova Scotia, with the other bridge being the A. Murray Mackay Bridge . Opened in 1955 and named after former Nova Scotia Premier and Canadian Minister of Defense for Naval Services Angus L. Macdonald, the Macdonald Bridge was the first bridge that crossed Halifax Harbour that was opened to traffic. The Macdonald Bridge was also the subject of the Big Lift, which was only the second time in history that the span of a suspension bridge were replaced while the bridge was open to traffic. Planning began in 2010 for the Big Lift, while construction took place between 2015 and 2017. Similar work occurred on the Lion's Gate Bridge in Vancouver, British Columbia before the project took place on the Macdonald Bridge. At this time, much of the bridge infrastructure is new, leaving only the towers, main cables and...

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l...

In a state which has no problem with an I-74/US-74 concurrency, I doubt that other route numbers in conflict will be an issue. Personally, I don't see a need for new route numbers of any variety, but that's not the "cool and trendy" way to approach this.

Good choices for the predictions. I too agree that the US 70 one will be an I-4x and the US 64 an I-5x. As for I-50, the Regional Transportation Alliance (the organization pushing for the US 64 I-route) in a blog post last updated on Feb. 9 (available at: http://letsgetmoving.org/rta-blog/raleigh-norfolk-495-44-50-89-56/) sees potential problems with I-50 due to the existence of NC 50 which also intersects I-95. Their preferred I-5x route is I-56.

Living in southeastern Virginia, I don't think Virginia's route numbering matters, because I fail to see where the political will will come from to foot the bill for any portion of this Interstate. Southeastern Virginia has many higher-priority projects for which funding has not yet been found, especially regarding a number of urban bridge and tunnel crossings. While I love the route (and the US 17/US 64 route is our favored route to get to I-95 southbound from Hampton Roads), I do not see the value of upgrading the portion north of the VA/NC state line, and I do not see circumstances where it is likely to become valuable enough to be worth the cost to taxpayers and governments here.
