More NC Highway Oddities on the way - Hello NC 36 and a Split NC 42

North Carolina is building a lot of new Interstates - personally, there are too many to keep track of - so we have Bob for that.  But as a result of new highways and new highway numbers, there's going to be conflict.

And that's the case with NC 42 and the soon-to-be-signed Interstate 42 in Johnston County.

Concerned about driver confusion and safety and first responder response, NCDOT has proposed that a small segment of NC 42 in Johnston County be redesignated as NC 36.  The new NC 36 designation would follow the existing NC 42 from NC 50 in Cleveland to the current US 70 Business east of Clayton.

When the US 70 corridor from Clayton east to Morehead City was approved as an Interstate nearly a decade ago, North Carolina requested Interstate 36 for the corridor.  Part of the reason was that the I-36 designation would not conflict with any existing state highways.  Unfortunately, the American Association of State Highway & Transportation Officials (AASHTO) disagreed.  They recommended Interstate 42 - as the newly designated corridor would run north of Interstate 40.  NCDOT accepted the ruling, and as a result, the conflict of two routes that would intersect each other and I-40 within miles of each other.

NC 36 will be routed through Clayton bridging the two NC 42's.

The plan to renumber NC 42 through Clayton should resolve that.  However, I believe the NC 36 change should continue eastwards to Wilson.  The reason is that NC 42 and Interstate 42 will intersect Interstate 95 about 19 miles from each other.  That's close enough, in my opinion, to continue with driver confusion for long-distance travelers along I-95.  I left a comment with NCDOT with my suggestion.  Will they listen to me? Stay tuned.

More Changes:

In addition to renumbering NC 42 through Clayton, NCDOT has proposed eliminating US 70 Business through Clayton and replacing it (or re-replacing it) with vanilla US 70 - or what used to be signed through the area until the Clayton Bypass opened 15 years ago.

The signage for Exit 306 will need to change.  Business US 70 East - will now be simply US 70 East.

This change will now eliminate the bried US 70/Interstate 40 multiplex between exits 306 and 309.  Exit 309 - the Clayton Bypass - will now be only Interstate 42.

NCDOT estimates that the changes will be signed in about a year.

The Local 4042 Nominclature:

Exit 312 - known locally as '4042' - will now be for NC 36.

For nearly 40 years, Exit 312 on Interstate 40 was known as '4042' by local residents.  As Johnston County grew, the 4042 interchange area added new restaurants, hotels, services, and of course traffic.  The interchange has been redesigned a few times. A current construction project is giving the interchange a total makeover - it will now become a Diverging Diamond Interchange (DDI) and a new interchange for nearby Cleveland Road is being built to take some of the pressure off the area.

The interchange was so well known that a local community news and information website was named after it -  In 2015, became

It will be interesting with Exit 309 being the new 40/42 interchange - what locals may now call Exit 312 - '4036' does work.

North Carolina Continues to Move Forward with Rail

2023 and the first half of 2024 have seen continued growth in North Carolina's passenger rail system.  From increased daily trains from Raleigh to Charlotte, federal funds for studying additional corridors, and receiving a historic grant to begin the construction of high-speed rail between Raleigh and Richmond, the last 18 months have been a flurry of activity at NCDOT's Rail Division.  And that's just the tip of the iceberg. As ridership and routes increase - the engine of North Carolina passenger rail trains will become a more common sight. (Adam Prince) Increased Passenger Train Service: On July 10, 2023, a fourth Piedmont round-trip rail service between Raleigh and Charlotte commenced.  The four Piedmont trains plus the daily Carolinian (to Washington, DC, and New York) bring the total of trains serving the two cities daily to five. The current daily Piedmont and Carolinian schedule between Charlotte and Raleigh (NCDOT) The result was over 641,000 passengers utilized pa

US Route 101 in Benbow, Garberville and Redway

The communities of Benbow, Garberville and Redway can all be found along US Route 101 within southern Humboldt County.  The former surface alignment of US Route 101 in Garberville and Redway once crossed the Garberville Bluffs along what is now Redwood Drive via a corridor constructed as part of the Redwood Highway during the 1910s.  US Route 101 through Benbow, Garberville and Redway was modernized by 1935.  US Route 101 would eventually be upgraded to freeway standards in Benbow, Garberville and Redway by extension of the Redwood Freeway during 1966-68.  As the cover photo the original grade of US Route 101 and the Redwood Highway can be seen at the Garberville Bluffs during 1934.  US Route 101 can be seen in the communities of Benbow, Garberville and Redway on the 1935 Division of Highways Map of Humboldt County .   The history of US Route 101 in Benbow, Garberville and Redway Benbow, Garberville and Redway lie on the banks of the South Fork Eel River of southern Humboldt County.  D
