I-20 to Wilmington Idea being Revived?

I was sent the above title link from a contact in the Myrtle Beach area. It was about information in a question and answer column that says there's been a revival of talks from local officials about bringing I-20 to Wilmington. Since SC has been against upgrading US 76, the new proposal would send I-20 north on I-95 to I-74 near Lumberton then east on an upgraded US 74, so SC wouldn't have to do anything but put up a few signs:

"Transportation planners say connecting Atlanta with Wilmington with one interstate number (I-20) would create the perception that it's easy to travel between the two cities, even if no new roads are built. That could help the N.C. State Ports Authority - and perhaps other businesses in the region - by allowing it to market the fact that two interstates serve the Wilmington area. A great deal of ocean cargo to and from Atlanta goes to ports in Charleston, S.C., and Savannah, Ga., both of which have limited capacity.

The idea would be to add the I-20 designation from Interstate 95 in Florence to its intersection with [I-74/]U.S. 74 near Lumberton, just by adding I-20 signs. Then, I-20 could run concurrently with U.S. 74 into the Wilmington area.

U.S. 74 would have to be upgraded to interstate standards, making it I-74. But that would be expensive. All of the at-grade intersections on U.S. 74 would either have to be closed or modified by creating interchanges or flyovers.

There's also concern about the fact that heavier trucks are allowed on U.S. highways than on interstates, so converting U.S. 74 to I-74 could affect some truck traffic.

A movement has begun on the local level to encourage the N.C. Department of Transportation to begin discussions about the I-20 idea with the S.C. Department of Transportation and the Federal Highway Administration."

For the entire article, click the blog title. The I-20 question is about halfway down.

Commentary: Apparently having I-20 go to Wilmington is more sexy to Wilmington officials than I-74 (hey 2 major interstates (I-20, I-40) end in our city, we have to be important). They may also be assuming that I-74 is still going to Myrtle Beach, as planned in former Governor Easley's SE Transportation initiative. However, there is a new administration and a new effort at NCDOT to prioritize road projects. Currently, there are two unfunded interstate projects in SE NC on the table: Upgrading US 74-76 to Interstate standards from Whiteville to Wilmington, estimated in 2001 to cost $160 million (obviously, more now) and the building of I-74 from Whiteville to the SC border, estimated in 2005 to cost $641 million, and deemed not viable as a toll road by the NC Turnpike Authority. Which project do you think would be the higher priority? It certainly makes more sense then financially to send an interstate to Wilmington, the question what number would be on the shield?

I don't know if bringing US 74 up to interstate standards is as hard or expensive as the columnist suggests. Currently, NCDOT has already 3 projects funded to start next year or already underway to upgrade at-grade intersections on US 74 between NC 41 and NC 211. They are holding a public hearing in a couple weeks about closing off another intersection near the western junction with US 76. If Google maps are correct this leaves only about 5 other intersections to deal with between Lumberton and Whiteville, including an interchange(s) with NC 72 and NC 130. There are certainly more issues between Whiteville and I-140 in Wilmington, but the section of I-140 that would intersect US 74/76 is to be built next and upgrading of US 74/76 around the interchange is undoubtedly part of that project. The overall question then is if the upgrading of US 74 east of I-95 to Wilmington to an interstate is assured to happen some time in the future. Is it worth that much more to the economy to have this route signed as (or with) I-20 than just as I-74?

Did Caltrans just kill the G26 cutout US Route shields?

The US Route System was formally created by the American Association of State Highway Officials during November 1926. Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California. The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant. However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices. This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes. The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield. In the background Mount Whitney can be seen in the Sierra Nevada range. ...

May 2023 Ontario Trip (Part 3 of 3)

Over the years, I have made plenty of trips to Ontario, crisscrossing the southern, central and eastern parts of the province. Living in Upstate New York, it's pretty easy to visit our neighbor to the north, or is that our neighbor to the west? Ottawa is one of my favorite cities to visit anywhere in the world, plus I've discovered the charm of Kingston, the waterfalls of Hamilton (which is on the same Niagara Escarpment that brings us Niagara Falls), the sheer beauty of the Bruce Peninsula, and more. But I hadn't explored much of Cottage Country. So I decided to change that, and what better time to go than over Memorial Day weekend, when the daylight is long and I have an extra day to explore. On the third and final day of my trip, I started in Huntsville and made my way through Muskoka District and Haliburton County, passing by many lakes along the way. I stopped in towns such as Dorset, Haliburton and Bancroft before making a beeline down to Belleville and then over th...

Ghost Town Tuesday; Nichols, FL

A couple years ago I spent a lot of spare time exploring phosphate mining ghost towns in the Bone Valley of Polk County, Florida. One ghost town in particular called Nichols on Polk County Route 676 west of Mulberry caught my eye due to a relative lack of documentation on ghosttowns.com. Nichols was created in 1905 during the early phosphate mining boom in the Bone Valley region. For the time Nichols was unusual since it had company housing in the Nichols Mine site and private residences outside the gate. Nichols is only about two miles west of Mulberry which probably made it a somewhat reasonable commute even by the wonky standards of the early 20th Century. Most of the Bone Valley region was relatively remote which made commuting or homesteading impractical which is why there are so many ghost towns in the area. The company housing section of Nichols was phased out and abandoned by 1950. The Nichols town site is largely abandoned and could "possibl...

The idea of bringing I-20 to Wilmington is pretty exciting, but the details of the plan are not.

In reality, this plan would do nothing to improve traffic flowing from Wilmington to the west or south since existing highways will be used for the project. With the exception of a few stop lights, US-74 over to I-95 is a pretty smooth drive. How much time will upgrading this highway really save travelers?

The thought of bringing I-20 into Wilmington is only exciting if it takes a more direct route into town. There is no point to the I-20 extension unless South Carolina would cooperate and implement the more logical route. As for perception, does Joe 6-pack traveler really care that Wilmington is served by I-20 if he will essentially be driving the same highways he drives today?

I too have hard time seeing this happen. SC's just not going to do anything to make it easier for people to get to NC & bypass Myrtle Beach.

This is really only a proposal to attract more traffic to the Port of Wilmington. They are hoping that a single interstate direct connection from Wilmington to Atlanta will attract more ships.

Well until the Cape Fear Skyway is built truck traffic will still have to go through downtown Wilmington regardless.

It doesn't matter if Wilmington has 2 or 20 Interstate routes that terminate there, with respect to increasing cargo traffic at the port. I-40 ends several miles north of the shipping terminal. I-20 or I-74 or I-whatever will end several miles to the west. Truck traffic leaving the port westbound or northbound still has to negotiate surface streets to get to a freeway. If they want to steer more ships to Wilmington reroute 40 onto a new road to the east that would terminate at the port entrance, or extend 20 from 140 to the port on new freeway that would cut across Wilmington from west to east and also end at the port entrance. That gets the trucks in and out of town faster. Of course neither of these ideas will become reality because of cost or lack of will on the part of NCDOT or opposition from NIMBYs who dont want their house bulldozed for a freeway.
