Brian and I had a lot of posts about it in 2007:

Thanks for the trip down memory lane (or should that be Expressway?). Glad NCDOT investigated why the 540 exit were initially numbered wrong. That certainly never happened again (oh, forgot the original exit numbers for the Havelock Bypass were off by 19, glad they found that out without anyone's help).

I was amused by the comment from 2008 that without tolls NCDOT projected the rest of the Outer Loop would not be built by 2030. The current date for completing the tolled Triangle Expressway is 2028. Meanwhile, NCDOT just put out a reminder that the next toll increase starts January 1: https://www.ncdot.gov/news/press-releases/Pages/2025/2025-12-30-annual-toll-rate-increase-triangle-expressway-monroe-expressway.aspx
This means an increase of $0.12 from $4.05 to $4.17 if traveling the 18 miles of the original Triangle Expressway from N.C. 55 to I-40 in Durham and an increase of $0.14 cents from $4.19 to $4.33 if traveling the 18 miles of the new extension of the Triangle Expressway from N.C. 55 to I-40 in Garner. 

Once this final section is completed in 2028 the cost to drive all of the tolled portion will be $12.01 per trip.

$12.01 for 41 miles of roadway, so around 29 cents per mile.

The Monroe Expressway is $2.96 for 18 miles of roadway, around 16 cents per mile. At that rate, the full 41 miles of NC-540 would be $6.74, almost half the proposed / existing rates.

Quite the difference!

Most people will only be using parts of NC-540 as opposed to the entire southern loop, unlike US-74 where a lot traffic is through, but still. Expensive.

End to end the northern loop I-540 would be considerably shorter and toll-free. For the I-40 bypass the distances look about the same.

I know all the arguments pro and con about toll roads. Overall I am pleased to see them being built wherever.

NCDOT announces more temporary road closures as NC 540 extension work continues:

I did a quick export of proposed highways from NCDOT and SCDOT's GIS data: https://www.google.com/maps/d/viewer?mid=1Ln0FvUITN7_M18kVHbm-m3SVr76070k

Wow. One look at I-540 around Raleigh, and it makes me wonder if there might be some plan to redesignate the route as something even-numbered. Perhaps a loop of Interstate 87?

Given the thread, it'll be SC 67.

At this point no, but that has been discussed more than enough in the NC threads.

Charlotte: Issue here would be interoperability with NC/Cintra. If I were SCDOT, I wouldn't want to get sucked into a contract that prevents South Carolina from widening adjacent roads. Just by reading some other posts about I-77 Express Lanes north of Charlotte, it sounds like NC got a raw deal.

I-77 is already eight lanes to Rock Hill, so it would be questionable of what benefit the toll lanes on I-77 in South Carolina would bring.

Does that part of I-77 even have congestion issues?

Also, with regards to NC I-77 and Cintra, are they also going to operate the proposed I-77 express lanes south of "uptown" Charlotte? I would've guessed that after the mess that happened with the current lanes, NCDOT was taking over any future express lanes projects, like they are with the I-485 lanes.

I'm surprised no one else has mentioned anything in either the Charlotte or North Carolina threads...

The Charlotte City Council has rejected NCDOT's proposal with Cintra to construct the I-77 South Express Lanes, and directed their regional transportation board member to oppose it, citing further destruction of neighborhoods that were originally separated by I-77's original construction, as well as the aforementioned raw deal that NCDOT made with Cintra for the I-77 North Express Lanes.

Several news articles about it and the legislative aftermath, where the NC General Assembly is requiring Charlotte and neighboring cities to repay engineering costs to NCDOT (below is one).

https://www.qcnews.com/charlotte/charlotte-leaders-withdraw-support-of-i-77-expansion-project/

Regardless of whether NC builds the toll lanes south of Charlotte, there is no need for SC to add any lanes of their own. I-77 south of Carowinds Blvd sees 135,000 AADT. This is well within the serviceability of an 8-lane urban interstate. South of Cherry Rd (northern Rock Hill exit), the traffic drops below 90k AADT, which would be fine even for a 6-lane interstate.

SC would have to build elevated lanes which would be prohibitively expensive. There's 9 miles between Cherry Rd and the NC line. SC is in the middle of a massive interchange project at SC 160 that I don't think they'll want to modify again for express lanes. Realistically, the only interchanges could be at Cherry Rd (tandem parclos with C/D system) and Carowinds Blvd. South of Carowinds, there are no problems. No need to build express lanes at a 10-figure price tag which would likely never see enough volume to pay off within 100 years. I wouldn't revisit this idea unless York County doubles its population. The express lane issue is strictly an NC problem until then.


As for NC, Charlotte is right to be worried about the Cintra agreement. As for their other concerns: any improvements to I-77 will take land, though it's not going to be to the extent the city seems to make it out to be. Much of the area along 77 is not residential, and there seems to be adequate land to add lanes with minimal disturbances.

NC needs to raise its gas tax because 41 cents per gallon by the state is inadequate for 80,000 miles of aging roads statewide not to mention the repairs from hurricanes every few years.

NCDOT isn't enforcing that the Cintra I-77 North Express Lanes be operated as they are intended. They were built to add capacity but the beginning toll rates are insultingly high resulting in empty lanes and a slower payback and return for the foreign lenders.

If they copied Atlanta's pricing and started at 50 cents for a few miles to get the lanes full, they'd collect more revenue faster even at lower rates.

Express Lanes are defined as having a sole purpose of offering a free-flowing lane of 45mph or faster for anyone to utilize at times they need to get somewhere faster with a predictable travel time. The toll rates rise to discourage too many additional people entering the lane that would slow it down below2 45mph.

Cintra should be forced to lower tolls enough to get the lanes fully utilized then increase rates to regulate the speed. The purpose of building them is not being fullfilled, citizens are incensed by $5 tolls to travel 2-3 miles which repeats until driving the full length of the lanes can cost $30-40 per trip.

The Express lanes on I-485 are state operated, but I'm not sure they think of Express Lanes the same way as in Atlanta, otherwise they would have forced Cintra to adjust their initial rates.

I will place a wager on the renaming of completed I-540/NC540 with anyone anytime. It will be renamed twice, first getting a beginning even number to indicate a full loop highway that will be split into an interstate and NC route until the bonds are paid off and then it will become one interstate designation with the even initial number.

I won't argue about it and don't care if a meeting in the 1990s decided to keep 540, that's not relevant today. So anyone who wants to wager that it stays 540 after 2028 when finished, speak up now. $50, $100, $500?
