It's not 36 and 89; it's....42! and......................87?!?!?

Well Interstate 36 tags won't be climbing up the blog list after all.  The American Association of State Highway and Transportation Officials (AASHTO) reviewed North Carolina's two interstate requests of Interstate 36 for the US 70 Eastern Corridor and Interstate 89 for the US 64/17 Raleigh-Norfolk Corridor and suggested two different numbers that NCDOT agreed to.  They are:

Interstate 42: This is the Clayton /Morehead City Super 70 Corridor.  It appears that AASHTO wanted to have continuity with the numbering grid.  I-42 will run completely north of Interstate 40.  NCDOT's concern for duplication with NC 42 was overruled.  Now, the question is will NCDOT rename all or part of the NC 42 which intersects both Interstate 40 and Interstate 42 before/after the new Interstate's western terminus.  The exit after/before what will be I-42 on Interstate 40 is NC 42.  In fact that intersection is known locally as "4042".  In fact, there was a local news and information themed website with the domain name 4042.com. (The website changed names in 2015 - foreshadowing perhaps?)  Also, the first/last exit before Interstate 40 on what will be I-42 is NC 42.   In addition, the distance on Interstate 95 between Interstate 42 and NC 42 will only be 29 miles.

I did ask NCDOT if as a result of AASHTO's decision will they renumber NC 42.  As of the publication of this blog entry, NCDOT has not responded.




NCDOT, however, was quick to produce Interstate 42 shields at the recent ribbon cutting ceremony for the completion of the US 70 Goldsboro Bypass.  Photo via WNCN.


Interstate 87:  This is the number for the Raleigh to Norfolk US 64/17 corridor.  I am surprised AASHTO kept it as a North/South route.  Also, this seems to be AASHTO trying to be consistent to the numbering grid as much as possible.  Like Interstate 89 in New Hampshire and Vermont, Interstate 87 exists in New York and this would be a duplication.  Instead, AASHTO tried to stick to the grid and the Raleigh - Norfolk corridor lines up with Interstate 87 better than Interstate 89.

I don't think NC DOT will try to renumber NC 87, a pretty lengthy route itself, as it is far enough away from the I-87 corridor to be entirely confusion.

So what's next?  The designations are pending the Federal Highway Administration's (FHWA) approval.  Once granted, NCDOT can start erecting signs.  I do expect that once NCDOT gets the FHWA's blessing, they will petition AASHTO for the approval to place Interstate shields on portions of these two corridors.  For I-42, full Interstate status for the Clayton and Goldsboro bypasses should be requested. For I-87, I-40 to US 64 Exit 429 should also be requested.  Time will tell - the next AASHTO

On one hand, the feds made a major error with the destinations but on the other hand, NCDOT has only itself to blame due to the 540 fiasco less than a decade ago. Once DOT decided to duplicate 540 as a state road in conjunction with the interstate, it violated its own policy

The story on how the unbuilt US 40 Expressway in Brownsville took 40 years to complete.

For nearly four decades, the four lane US 40 just east of Brownsville came to an abrupt end - shown in the photo above - at Grindstone Road in Redstone Township.   In the late 1960s, what was then the Pennsylvania Division of Highways (PennDOH) extended a new four lane alignment of US 40 eastwards from Broadway Street slightly over one mile to Grindstone Road where an incomplete diamond interchange was built.  Earlier in the decade, PennDOH had built a four lane US 40 in Washington County into Brownsville complete with a new crossing over the Monongahela River known as the Lane Bane Bridge.  This new highway and bridge allowed US 40 to bypass the older Intercounty Bridge and downtown Brownsville. 

After this new highway opened, nothing would happen to it for nearly forty years.  US 40 traffic would use the ramps for this planned diamond interchange and then jog on Grindstone Road briefly before continuing towards Uniontown on the original National Road. 
What is unknown (at least to…

The story of the Boy Scout Ramps on Interstate 79 North in NW Pennsylvania

If you are traveling on Interstate 79 North of Pittsburgh, you may notice the remnants of a set of off and on ramps at mile 100 just north of Exit 99 (US 422).  There's a story behind these ramps.  Forty years ago, these ramps were built specifically for two Boy Scout Jamboree's that were held at Moraine State Park - 1973 and 1977.  The ramps purpose were to provide access to the north shore of Lake Arthur where the bulk of the festivities and campsite for the Jamboree were located.  (Lawrence County Memories has a great write up and map of the festivities on its site.)

Not long after the Jamboree ended the ramps were abandoned.  There are still remnants of the Boy Scout Ramps today.

The google street view image above gives a view along West Park Road of where the set of ramps intersected the highway.  The ramps provided direct access to North Shore Drive (which is the right tur…

The few clues of the Northern Durham Parkway

Sometimes when you look through a box of maps for the first time in five years, you come across something you may have easily over looked.  Such was the case when I found a 2004 (so rather recent) map of Raleigh.  This map was made by the Dolph Map Company for WakeMed.  In the Northwestern corner of Wake County, there were two items to the map showing roads that are still not in existence 13 years later.

The road is the Northern Durham Parkway - this is a proposed 19 mile highway from US 501 north of Durham to the Raleigh-Durham International Airport.  The first proposals for this highway date back to 1967 when Eno Drive-Gorman Road was listed on the Durham Area Thoroughfare Plan. (1)  Other proposals called the highway the Northwest and Northeast Durham Loop. (2)  The route would serve as a northern and eastern bypass of Durham almost serving as a near loop.  The route was fought vigorously for three decades by the Eno River Association citing concerns for the the Eno River, nearby n…
