I-40 and I-440 Signage Changes Around Raleigh

Image
By
I promised in my earlier post that I'd put additional photos in a future entry regarding signage changes along I-40 in Raleigh. These changes are taking place with the re-designation of I-440 as an East-West route across the top of Raleigh and its discontinuance on I-40. NCDOT had a press release last week saying they had completed the I-440 re-signing. Here are some photos taken in January showing examples:
This is on Wade Avenue approaching the I-440 interchange, the previous 'Inner' and 'Outer' designations have been replaced by 'East' and 'West.'
Here's a closeup of the second sign in the interchange. Another 3 control city sign. The trivia about this sign is that only 1 of the cities (Wake Forest) does either of these routes go to. The other destinations might be more appropriate on a I-40 US 64 sign, since you need to get on 64.
This is signage along the roadway itself, all that was done here is place an 'East' panel over the I-440 shield.

Now for sign changes on I-40 itself. I took a detour further east on I-40 from I-440 East down to Jones Sausage Road (brief pause for any snickering) and back to see signage on I-40 West approaching the Beltline. The first sign is:
The construction signage does not relate to the signage project but an ongoing paving job on I-440. Notice the lack of control cities. A 1/2 mile further this is the next sign:
This sign assembly has both a new sign for I-40 and a revised sign for I-40, notice the only control city is Durham. Is this to help or warn drivers? It's the same for the next signs assembly as seen in the previous post:
They've left the previous ground signs telling people to use 440 for north and east Raleigh and I-40 for south and west Raleigh, but an overhead sign might be more helpful. While these are definite changes from the previous signs, not all has been changed along the I-40 portion, like:
This assembly I assume has been there since I-40 was connected to the Beltline and has survived several route changes, additions, and now subtractions. How long will it remain?
As for the signing of I-40 after the merge, there are new I-40 and US 64 signage:
These are new signs, but they don't follow the recent NCDOT practice of putting route shields with more than one designation on green signage. Maybe this contract has been put off for so long it still was using the old specifications. As for the rest of I-40/US 64 there have been some new signs, but, at least westbound, not too many. The signage where I-40 meets I-440 again has not changed.

I also took some photos related to the I-40 widening project in Cary which begins at the end of West I-440 and continues to Wade Avenue:
Barriers have been placed to protect workers in the median and bringing the new lanes down to grade has begun. To speed up the process NCDOT's contractor is using a conveyor system:
To take the dirt and rock from the median over the highway to awaiting trucks. Another conveyor belt will take asphalt to the site when the roadbeds are completed. It appears workers are concentrating their efforts now between Wade Avenue and the NC 54 exit due to the presumed convenient location of the porta-potty:
This design-build project is supposed to be completed by the end of June 2011. If you would like more information go to the official NCDOT site at: http://www.ncdot.gov/projects/I4744/

Bleriot Ferry - Alberta

By
  Alberta operates six ferries scattered throughout the province. Roughly twenty to twenty-five kilometers up the Red Deer River from the town of Drumheller is one of the most scenic ferry crossings in all of Wild Rose Country, the Bleriot Ferry. Using the North Dinosaur Trail (Alberta Highway 838, or AB 838), the Bleriot Ferry provides a scenic river cruise of sorts in the Canadian Badlands. The Bleriot Ferry started operating in 1913 as the Munson Ferry when a few bridges crossed the Red Deer River. The ferry was started by Andre Bleriot, the brother of famed early aviator Louis Bleriot, who became famous for being the first person to fly over the English Channel. At the time, the Alberta provincial government commissioned local residents to run the ferries. There were several ferries along the Red Deer River, and not only did they serve as vital transportation links, but they also served as local social hubs, since everyone had to take the ferries to go places. Over time, as the...

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

By
In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l...

I-73/I-74 and NC Future Interstates Year in Review 2024

By
Welcome to another annual review of progress in constructing North Carolina's New and Future Interstate routes. While 2024 was not too exciting, with no new segments of major routes opening, there was 1 new interstate signing, another proposed new interstate route, and the near opening of a new segment for 2 routes. As tradition, I will start off with a review of what happened with I-73 and I-74 and then move on to the major news of the year about the other new and future routes. Work continued on the I-73/I-74 Rockingham Bypass through the year. The last few months have been hoping for news of its opening before 2025, without luck. Signs of its near completion included the placement of new signs, many with interstate shields uncovered, along the Bypass and intersecting roadways. For example, these went up along US 74 East: Overhead signage at Business 74 exit which contains the future ramp to I-73 North/I-74 West. Signage was also updated heading west on US 74 approaching the unop...
