AASHTO's Latest Response to NCDOT's Route Numbering Requests

AASHTO SCOH has posted their responses from their October meeting of the Special Committee on U.S, Route Numbering in Hartford on a single Word document, link below. They have not yet posted the documents with specific responses to each application, however. Hopefully these will be posted soon so a better understanding for the decisions can be deciphered.

For NC, the results are mixed. They approved the applications for I-440 (dropping it from the I-40 portion of the Beltline) and the application for the US 17 Windsor Bypass. They approved the I-540 and I-140 applications though conditionally, citing the need for a revised application for both, requesting that I-540 be marked Future and possibly a spur (?) and I-140 be revised to designate that route a spur(?). They conditionally approved the I-73 application but also want the application resubmitted to have the route designated Future I-73 'since it is not complete.' They again disapproved the US 117 move back to its original alignment from the I-795 freeway and the elimination of Alt US 117 because 'information submitted appeared to be conflicting and inconsistent'.

Go to the AASHTO Document

Commentary: My initial reaction to this is 'huh?'. The I-540 extension application was for the extension from US 1 to the current end at US 64/US 264. Aren't those NHS routes? Why does AASHTO want Future signage? Also, what is this about a spur designation? Doesn't the odd numbers 140 and 540 indicate that already? Or have they forgotten how 3-digit interstates are numbered?

As far as I-73 goes, it is signed on an interstate standard freeway that begins at an interstate (I-85) and ends at another interstate (I-40) for now and could be extended to a expressway elevated to NHS status (Bryan Blvd.) as approved by the FHWA. So why does it need a future banner? Yes, its not 'finished' and won't be in NC for many years to come, but there are other segments of I-73 signed as an interstate elsewhere despite the whole road not being complete. Maybe some at AASHTO resent that the road was legislated into existence without their consent? The I-73 signing is important for traffic using the southwestern part of the Greensboro Loop since I-40 is being taken off the Loop (NCDOT never applied to change I-40's route to the Loop in the first place, so that's why that wasn't included among their applications). Since all of NCDOT's interstate applications have already been approved by the FHWA or through legislation, I believe there's little AASHTO can do anything about changing the signs that are already up. It may though cost NCDOT time and effort to have to reapply for these various routes in order to remind AASHTO of this and have them finally agree to the changes.

As for the US 117 application, the later one was clearer than the first. NCDOT expanded its explanation including the history of the building of the US 117 freeway, reminding them AASHTO approved the move of US 117 to it and the creation of Alt US 117. They then indicated the history of I-795 approval and the wish to revert US 117 to the route it had run on for many decades. They even included the history of the application to AASHTO that they approved of extending US 117 to I-95 and the wish it be truncated back to its original terminus. From my reading of all that, I don't see anything that would be too confusing, especially since they had a previous application to build on. Do these two organizations speak two different languages? Would it be possible for someone at AASHTO to call NCDOT to clear up any confusing issues? From all appearances, they seem to just mail memos back and forth to each other and no one on either side takes it upon themselves to clear up any misunderstanding.

In any case, NCDOT and AASHTO always make the designation of new routes interesting.

Seems like the AASHTO might be on crack or something. lol.

They also forgot to mention the Nevada application for TEMP US-50/395.

Read the I-540 request carefully.

"The proposed action will increase the overall system capacity of the existing roadway network and will divert traffic from
secondary roads in an area of Wake County that is experiencing substantial residential growth.The need for an additional
transportation facility in the southern and eastern Wake County is based on a combination of factors including transportation
demands, social and economic demands, and safety considerations. The Southern and Eastern Wake Freeway will link the
towns of Clayton, Garner, Fuquay Varina, Holly Springs, Apex, Cary, and Raleigh. It will also connect the major radial routes
in the southern portion of Raleigh and reduce traffic volumes on the Raleigh Beltline (I-440), I-40, NC 42, NC 55, and Ten Ten
Road (SR 1010) by providing an alternate route for local and through traffic. The Southern Wake Freeway is a component of
the Raleigh Outer Loop and will tie into the Western Wake Freeway near Apex and the Eastern Wake Freeway near Garner.
The Eastern Wake Freeway will tie to the northern portion of the Outer Loop at the US 64 Knightdale Bypass."

This statement is a request for the Southern and Eastern Wake Expressway, but all of the supporting maps and doc refer to the segment north of US-64. I think NCDOT was on something when they submitted this one.

An update; AASHTO has posted resubmitted applications they requested from NCDOT for the interstate routes extensions submitted for the October 17 SCOH meeting. NCDOT, however, did not change their applications to what AASHTO asked for. Instead, they sent the same applications with additional highlighted sentences along with a copy of a letter from the FHWA sent to AASHTO 10 days before the meeting. The letter was in response to questions the Route Numbering Committee had about the NC Interstate requests. The letter indicated the FHWA approved all the interstate extensions NCDOT asked for. They also specifically pointed out that they can be properly signed as full interstates stating a Future Interstate designation is only applicable to a highway not on the FHWA list of current interstate routes, which is not the case here. As you recall AASHTO asked for reapplications because they wanted NCDOT to request future interstate routes for I-73, I-140 and I-540.

So what happened? Is it a simple failure to communicate from one side or the other. Did the Route Numbering Committee get the FHWA letter? If so, did they read it? The FHWA letter also points out that several of the interstate routings had already been approved by AASHTO before! Did any of the committee members look up past decisions? While some of the NCDOT applications may have been somewhat confusing, the FHWA letter would have helped clear up much of that, in that it spells out exactly what NCDOT is asking for and why the FHWA agrees with it. In the end it really doesn't matter if AASHTO approves the routes or not since the FHWA already approved the highways and AASHTO has approved the route numbers.

Horace Wilkinson Bridge (Baton Rouge, LA)

Standing tall across from downtown Baton Rouge, the Horace Wilkinson Bridge carries Interstate 10 across the lower Mississippi River between West Baton Rouge and East Baton Rouge Parishes. Unusually, the bridge is actually named for three separate people; three generations of Horace Wilkinsons who served in the Louisiana State Legislature over a combined period of 54 years. Constructed in the 1960s and opened to traffic in 1968, this is one of the largest steel bridges on the lower Mississippi. It’s also the tallest bridge across the Mississippi, with its roadway reaching 175 ft at the center span. Baton Rouge is the northernmost city on the river where deep-water, ocean-going vessels can operate. As a result, this bridge is the northernmost bridge on the river of truly gigantic proportions. Altogether, the bridge is nearly 2 ½ miles long and its massive truss superstructure is 4,550 ft long with a center main truss span of 1,235 ft. The Horace Wilkinson Bridge is one of the largest

Sunshine Bridge (Donaldsonville, LA)

Located about halfway between Baton Rouge and New Orleans in southern Louisiana, the Sunshine Bridge spans the lower Mississippi River near the city of Donaldsonville as part of the longer Louisiana Highway 70 corridor, which connects Interstate 10 and Airline Highway (US 61) with US 90 in Morgan City. In the years following World War II, the only bridges across the lower Mississippi River in Louisiana were located in the area of the state’s two largest cities – Baton Rouge and New Orleans. Postwar agricultural and industrial development along the river in this region led to the planning of a series of infrastructure projects in southern Louisiana that were aimed at spurring this development and modernization of the Delta region. One of these projects was known as the Acadian Thruway and was developed in the 1950s as a toll road intended to connect greater New Orleans with Lafayette and points west while providing a high-speed bypass of the Baton Rouge metro area. The Thruway, which

Veterans Memorial Bridge (Gramercy, LA)

When we think of the greatest engineering achievements and the greatest bridges of North America, we tend to focus on those located in places familiar to us or those structures that serve the greatest roles in connecting the many peoples and cultures of our continent. Greatness can also be found in the places we least expect to find it and that 'greatness' can unfortunately be overlooked, due in large part to projects that are mostly inconsequential, if not wasteful, to the development and fortunes of the surrounding area. In the aftermath of the George Prince ferry disaster that claimed the lives of 78 people in October 1976 in nearby Luling, LA, the state of Louisiana began the process of gradually phasing out most of its prominent cross-river ferry services, a process that remains a work in progress today. While the Luling-Destrehan Ferry service was eliminated in 1983 upon completion of the nearby Hale Boggs Memorial Bridge, the ferry service at Gramercy, LA in rural St.
