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.

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.

California State Route 88 the Carson Pass Highway

Between 2016 and 2017 I drove the majority of California State Route 88 from CA 99 in Stockton east over Carson Pass to CA 89.






CA 88 is a 122 mile state highway from CA 99 in Stockton east over the Sierra Nevada Range to the continuation route Nevada State Route 88 at the Nevada State Line.  CA 88 is known as the Carson Pass Highway.  Carson Pass at 8,574 feet above sea level along CA 88 is an all-year Mountain Pass in the Sierras and on occasion designated as Temporary US Route 50 when conditions are bad over Echo Summit. 

CA 88 was not one of the original Signed State Highways.  CA 8 was the original designation over Carson Pass which can be seen on the 1938 California State Highway Map.

1938 State Highway Map

CA 8 was substantially different than CA 88 west of Jackson as it largely follows the current route of CA 26.  From US 99E in 1934 and later US 50/99 in 1936 from Stockton CA 8 originally used the following route to reach Jackson:

California State Route 49; The Golden Chain Highway (CA 41 north to CA 16)

Last year I traveled California State Route 49 from CA 16 north to CA 89 in one continuous trip.  This year and in early 2016 I traveled the rest of CA 49 south to CA 41 in Oakhurst.  This blog post consists of photos of the highway from those time periods and historical information about the southern part of CA 49.


This blog post is meant to be a continuation of the previous one I did regarding CA 49 from CA 16 north to CA 89.  A link to said blog post can be found below:

California State Route 49; The Golden Chain Highway (CA 16 north to CA 89)

As stated in the previous blog post; CA 49 is an approximately 295 mile long north/south highway which traverses the traditional Gold Rush Country of California.  While I intend to discuss county level historical alignments of CA 49 as I did in the first blog post I thought this would be a good place to discuss the backstory of highway.

CA 49 was first signed in 1934 along a series of Legislative Route Numbers ("LRN") that were large…

Caliente-Bodfish Road/Kern County Road 483

Back in 2016 I took Caliente-Bodfish Road south towards California State Route 58 while leaving the Sierra Nevada Range after looking for the town site of Old Kernville.






Caliente-Bodfish Road is also known as Kern County Road 483 which I believe is an internal designation for mountainous roadways within the Sierra Nevada Range.  Caliente-Bodfish Road begins at Kern Canyon Road (Old California State Route 178) at the southern extent of Bodfish and climbs over the southern most extent of the Sierra Nevada Range approximately 35 miles to Bena Road near Caliente.  Caliente-Bodfish Road is a full two-lane road despite traversing some narrow terrain in the Sierras.  The high point on Caliente-Bodfish Road appeared to be near 4,000 feet above sea-level and I would estimate that there grades as high as 10% in places.

South of Bodfish Caliente-Bodfish Road ascends quickly above the community on a series of switchbacks.  There is no official overlook but there is a hell of a view of Bodfish an…
