Why I-73/74 in North Carolina?


Interstates 73 and 74 were initially authorized by the Intermodal Surface Transportation and Efficiency Act (ISTEA) of 1991, as one of several high priority transportation corridors to be designated across the country. The I-73/74 corridor, Corridor 5 as defined by ISTEA, and in later amendments to that act including the Transportation Equity Act for the 21st Century of 1996 (TEA-21), defined both the routing of a new Interstate 73 through Michigan, Ohio, West Virginia, Virginia, and North and South Carolina and the extension of already existing Interstate 74 between Cincinnati, Ohio, and South Carolina.(1) Lobbying to include this route, initially described as a Detroit to Charleston interstate, as a High Priority Corridor in the 1991 Act was encouraged by many business and transportation groups as a way both to enhance economic development potential throughout the corridor (2) and as a means to encourage funding many previously existing highway upgrade projects along the path of the proposed highways.

Initially the corridor was to be served by one interstate, I-73, but when officials in Virginia, including newly designated chairman of the Senate transportation subcommittee John Warner, sought a more eastern path for the new corridor through Roanoke disputes arose over the proposed routing, especially in the Carolinas (both Greensboro and Winston-Salem wanted the new interstate in North Carolina, South Carolina feared the interstate would end in Wilmington and not benefit the South Carolina coast). A compromise was reached between Senator Warner and Senator Lauch Faircloth of North Carolina in 1995 whereby I-74 would be extended from Cincinnati and serve as a seperate route where disputes over the path of I-73 existed. I-74's route would serve Winston-Salem and I-73 Greensboro (critics claimed at the time that Faircloth's support for the I-73 route through Greensboro was aided by a major donor to his campaign, the Jefferson Pilot Insurance company having land along the future I-73 route). Later Faircloth and Senator Strom Thurmond of South Carolina reached a compromise over the where the two routes would enter the Palmetto State. I-73 was promised to enter South Carolina near Rockingham while the I-74 corridor would enter south of Wilmington.(3)

Though the routes were approved by Congress, no money was appropriated to pay for any construction. It was left up to each state to decide when, and if, I-73 and I-74 were to be built. Later the termini for the I-73 corridor was changed to run from Sault Ste. Marie, Michigan to Georgetown, SC.

On July 25, 1996, AASHTO accepted Interstate 73 and the Interstate 74 into the Interstate Highway System within the states of South Carolina, North Carolina, and Virginia. The approved route for I-73 was from the I-81/ I-581 intersection in Roanoke, Virginia south to the intersection of US 17 and I-26 in Charleston, SC. The southern terminus was later truncated to US 17 at Georgetown, SC. For I-74 the route approved was from the more northern of the two intersections of I-81 and I-77 near Wytheville, Virginia to the I-73/I-74 junction near Myrtle Beach, South Carolina.(1) In 1997, North Carolina took the lead in signing these two interstates along some of its highways.

I-73/74 in North Carolina

NCDOT planned Interstates 73 and 74 to use a combination of existing highways and new roadways to make their way through North Carolina. I-73 would roughly parallel current US 220 from Virginia to Rockingham and then US 1 (later US 74 east then the path of NC 38) into South Carolina. I-74 would enter with I-77 from Virginia and then roughly follow US 52 to Winston-Salem, then heading east by picking up US 311 to US 220 north of Asheboro, then following it (and I-73) south to US 74 in Rockingham, then finally proceeding east on US 74 to Whiteville then south into South Carolina. A revised 2015 NCDOT map of the proposed routings of I-73 and I-74 by NCDOT is below, it shows the changes to the entry point of I-73 into South Carolina agreed upon in 2005 (and now reflects the revised routing of I-73 around Greensboro approved by the FHWA in 2011)(4):

If fully constructed as proposed, I-74 would be North Carolina's second longest interstate, totaling about 300 miles*, trailing only I-40's 420 miles but ahead of I-85's 233 miles. I-73 would be the fourth longest at about 140 miles, beating out I-77 (105 miles) and I-26 (71 miles). There has been greater progress in constructing I-74 so far than I-73, with four distinct segments of I-74 currently signed as full interstate as of June 2015 totaling almost 125 miles, one freeway section marked as a future interstate totaling 11 miles, and 7 miles under construction. The two sections of I-73 signed as a full interstate (the Greensboro Loop and US 220) total 78 miles, while an additional 13 miles are signed as a future interstate and an additional 20 miles are under construction. Percentage-wise, however, since I-73 is much shorter, more of I-73's routing is signed as either a full or future interstate (65%) than I-74's (45%).

Status of I-73 and I-74 as of January 2016:

Image of NC Interstate 73 Shield, from Shields Up!Though little expansion of I-73 occurred in the decade since the road was signed, from 2009 to 2015, progress on building I-73 has been significant. The years 2009 and 2010 saw several critical achievements in the Greensboro area, including I-73 replacing I-40 as the primary route on the SW section of the Greensboro Loop and the highway now designated I-73/US 421 and Bryan Blvd. classified as an National Highway System Route, allowing I-73 to be routed north of I-40 along current Future I-840. Both I-73 and I-840 were accepted into the interstate system in August 2011. Construction to build a new connector freeway to take I-73 from NC 68 to US 220 near Summerfield started in 2014 along with the freeway to connect NC 68 to Bryan Blvd. Construction of that project was moved up from 2016 in June 2013 and both are expected to be completed by the end of 2016. In connection with that project, the widening of US 220 south of NC 68 to the site of the connector freeway began in April 2012, both projects are to be completed by the summer of 2017.

Elsewhere along the corridor, the completing of the rest areas in the Seagrove area along I-73/74 was finished in January 2010. The upgrading of US 220 through Asheboro, a project started in the fall of 2009, was completed in October 2012. NCDOT has changed the exit numbers along this section to reflect I-73's mileage. A related project replaced exit signs as well as numbers from Ulah to Emery was completed in October 2013. The contractors also updated the route with full interstate shields by December 2013, allowed by the FHWA once the Asheboro project was completed. This now means that I-73 is signed all the way from I-40 in Greensboro to just north of Rockingham, almost 80 miles. Meanwhile some changes to the dates of remaining projects occurred in 2011 after the release of the 2012-2018 and subsequent STIP documents, organized under a different funding formula. This has moved several projects to unfunded and a start date, as of June 2015, of after 2025. The first segment in building the US 220 Rockingham Bypass, also to carry I-74, the upgrading of 3 miles of US 220 to interstate standards, started in January 2014, and is to be finished by 2017.

As for other states, SC got approval to build its northern section of I-73 which will connect to US 74/Future I-74 near Hamlet. A funding source has been approved to build an interchange at I-95 in Dillon with the route connecting to US 501. The I-73/74 Association announced in October 2008 that NCDOT had completed right-of-way purchases to upgrade US 220 to an interstate north for Greensboro to the VA state line. Work will not start until Virginia starts construction of its own section. A new route for I-73 around Martinsville was approved by VDOT but and was approved by the FHWA in 2012, however no progress on financing the route has been made.

Unlike I-73, not all the progress on completing I-74 since 2009 has been behind the scenes. The last leg of the High-Point "East Belt" extension, from Business I-85 to I-85 which had started construction in late May 2007, along with the first half of the '311 Bypass' from I-85 to Spencer Road, were completed in November 2010. The entire route from Main Street (former Business 311) in High Point east to Cedar Square Road in Glenola was signed I-74/US 311 upon completion. Construction on the remaining section of 'US 311 Bypass' freeway started in early September 2008. Most of the major work constructing the bridges for intersecting roadways and the interchanges with current US 311 in Sophia and US 220 in Randleman had been completed by the end of 2012, however the section was not finally completed until June 7, 2013. NCDOT got permission to sign US 311 east of I-40 in Forsyth County as I-74 in April 2013, however signs indicating this change were not placed until August 2014. With the replacement of Future I-74 shields along the US 220 Corridor in December 2013, I-74 is now continuously signed from I-40 east of Winston-Salem to just north of Ellerbe, a total of 86 miles.

The major I-74 construction project now underway (other than the current Rockingham Bypass project with I-73) is the Winston-Salem Northern Beltway. Work began on the first leg between Business 40/US 421 and US 158 in the fall of 2014. The 2016-2025 STIP indicates work on two other sections, between US 311 and Business 40 will start in 2022, the remaining segments are now funded, due to changes in the transportation budget formula by the NC governor. It is unknown when construction will start on the remaining segments, but a design-build contract to build the future interchange between the Beltway and US 52/Future I-74 is to be let in September 2016. NCDOT seems to have adopted a piecemeal approach to building I-74 east of I-95. Two intersections along US 74 between Lumberton and Whiteville were upgraded to interchanges during 2012. NCDOT signed these two exits using I-74 mileage, along with all other existing exits along the current US 74/76 Whiteville Bypass by the end of 2012. Three more projects, one to build a bridge over US 74, the other two to replace intersections with interchanges are funded through 2025. There are no funds, however, for any other I-74 projects east of I-95 at this time.

Current Reality of I-73/74 Progress

In 2004 NCDOT thought I-73 could be signed as a full interstate south of Greensboro to just north of Rockingham by 2010 and that much of I-74's route could be completed by 2014.5* Financial realities caught up with NCDOT though and projects were either moved back or remained unfunded.Though I-73 is now signed between Greensboro and Ellerbe, many of the proposed I-73/74 projects were kept unfunded and thus delayed now to after 2025 in the 2016-2025 State Transportation Improvement Plan (STIP) released in June 2015 (the new STIP procedure lists only projects to be completed within a 5 year period, plus all other funded projects due to start by 2025). An NCDOT official remarked in 2005 that the two routes may not be completed for decades.(7) NCDOT estimated at that time the total cost of building the highway to be $2.2 billion of which only $475 million currently had been funded.8

It now has been more than ten years since SC and NC officials met for an I-73 summit Feb. 11, 2005 in Myrtle Beach to discuss Interstate 73 plans, where an official route across the border using NC/SC 38 was chosen. (See I-73 Segment 13). Officials at that time thought construction on this part of I-73 could start as soon as 2009.7 However, no funded project has been approved by either North or South Carolina. South Carolina did select its corridors for how I-73 will be routed south of Rockingham to I-95 in August 2007, but is still, as of 2016, trying to come up with the money. How soon it may be built depends on funding, perhaps as a toll road, which may include the short 5 mile section in NC. Meanwhile, completion of both routes may be many years off. Optimistic projections have I-73 existing from (just north of) Greensboro to SC (and maybe in SC) within a decade and I-74 completed west of I-95 to near Winston- Salem about the same time.

* this is using the proposed routing as discussed in I-74-Segment 18, mileage from NCDOT Strategic Corridors list (No. 30), a newly discussed alternative routing generally following NC 410 and NC 130 would be shorter.

I-73/74 FAQ

Answers to some frequently asked or interesting questions...:

Do you have any maps that would show if my property is in the way of the proposed I-73 and/or I-74 freeways?

I collect my information from several sources including the NCDOT website and media outlets. I typically don't have detailed information on where a highway is to be constructed at a specific location. If you think that you may be impacted by a future freeway I suggest you contact someone in your local NCDOT divisional office. They should have plans or can point you to the project engineer for the specific contract who should have detailed information. Divisional office phone numbers are available at the NCDOT website, www.ncdot.org.

Why are some parts of the I-73 and I-74 routes marked as Future while others have regular interstate signs?

The signing of a particular route as a full interstate is decided on by the FHWA in coordination with NCDOT and depends on a number of factors including whether the route meets current interstate standards, is connected to another interstate highway, and whether a project is funded. Routes that are up to current interstate standards and are connected to other interstates at both ends or at one end where the other end is a highway that is part of the National Highway System (such as I-74 near Mt. Airy) can be signed as interstate highways. Routes that are up to interstate standards but are not currently connected to another interstate (like I-74 along the US 74 Rockingham Bypass) can be signed as future interstate routes. Freeways that currently do not meet interstate standards but have a funded project in the books to improve them can also be signed as future interstates (such as I-73/840 around Greensboro). Freeways with planned upgrades but no funding can only be signed as a 'Future Interstate Corridor' (like US 52 north of Winston-Salem). These signs, which are really more useful for advertising a future route than as a driver's aide, can also be found on routes that will be eventually supplanted by an interstate (such as US 74 between Rockingham and Laurinburg). As with all regulations, there are exceptions. For example, I-285 south of Winston-Salem could be signed as a Future Interstate route but has only received Future Corridor signs, both perhaps decisions made in an attempt to save money from not erecting short-term future signage. A project to upgrade this route started in late 2013. Interstate 74 between Winston-Salem and High Point had its signage upgraded from Future to Interstate 74 without any upgrade to the highway due to a misunderstanding as to whether the highway was up to interstate standards (see I-74 Segment 5), a project to start in the spring of 2016 may widen the shoulders to interstate standards as part of a repaving contract.

Why use the I-74 number when the route runs further south than I-40? Wouldn't an I-20 or I-30 something number be more appropriate?

The I-74 number was written into the legislation authorizing the routes with the idea that I-74 would be extended from Cincinnati to Myrtle Beach sometime in the future. Similar legislation would be needed to change the route number and until the plans to extend the route in Ohio are declared officially dead there probably would be little incentive for anyone to introduce a bill to do that. If the route finally runs only from Mount Airy to Myrtle Beach, however, then maybe a better fitting number for the route could be considered. There are certainly a number of possibilities for a lower number. With the exception of I-30 there are no other even number interstates currently between 28 and 40. This would though end the unique co-routing of an interstate and US route with the same number in North Carolina, for better or worse.
