Nevermind, that our fair share of wet weather is during peak construction times of the year. We do have the exception of somewhat warmer winter but, that is also in flux. Glad you brought up the Basnight Bridge, that was 3 years of construction after 30 years of lawsuits over environmental issues. By all means explain away these complexities.You don’t have to close a span. You can widen a bridge with traffic moving on it. Hell, you can even replace a bridge with traffic moving on it by doing it in sections.It’s certainly doable without removing traffic. Reduce the speed limit to 55 mph, shift traffic to the far right of each bridge, put up construction barriers on the left, then work in the median to build more bridge.

An in progress example would be I-81 over the Potomac River. It has much more traffic than this spot on I-95: 53320 vs 17500 via bridgereports.com. And it has a narrower road deck since it has no shoulders. And they are expanding the bridges from two lanes each to three with full shoulders while maintaining two lanes of traffic on each bridge.

Not to mention, there's a full left shoulder on this bridge. It can certainly be widened.What about the bridge replacement they did in Virginia just north of the state line? The one further south that NCDOT is doing right now? Bridge replacements and widenings -can- be done and have been done countless times. It's not a hard task for NCDOT.

By all means explain away these complexities.At 1,150 feet long that is about the same length as the I-95 bridges over the Rappahannock River. The latter are almost 100 feet high and the former is a low level bridge. The I-95 bridges over the Rappahannock River were widened to 3 lanes each way in the 1980s.
Here's a video showing the construction sequence for the upcoming rehabilitation of the Green River bridges (1,050 feet long and 220+ feet high) on I-26 in Henderson County. The deck is being replaced and widened while maintaining traffic. Technically it will be wide enough to support an additional lane each direction, but I think it will require a design exception due to narrow shoulders. There is also the issue of the curve on the western side of the bridge not meeting today's requirements for design speed (signed as 50 mph eastbound), so it may not happen with that alignment anyway. The contract was supposed to be let last month, but it has been delayed a year due to funding issues.

plus I-26 is not a major commerce route like I-95.

Anytime I-95 is shut down for an accident, that's just an accident, there are backups due to the amount of traffic on that one route. It has the nick name "Main Street of the East Coast" for a reason. You think the transport industry is not going to have any input on what limitations are going to occur when, not if, the widening is going to occur. That's what the hell!!

That's what the hell!!What about the bridge replacements further south of there? Same roadway. The bridge replacements in Emporia, VA that finished a few months ago, different state, but same roadway. The massive construction around Fredericksburg and the new Rappahannack River bridges. The Occoquan River Bridges were widened from 6 to 8-lanes in 2013. The Springfield Interchange in 2008. The Woodrow Wilson Bridge Replacement in 2008 - 2012.All on I-95.
^What about VDOT widening the Occoquan River Bridges in 2013 from 3 to 4 lanes each way?
Good explanation for the construction but, that didn't add a lane, plus I-26 is not a major commerce route like I-95.
Quote from: goobnav on July 12, 2019, 03:44:04 PMGood explanation for the construction but, that didn't add a lane, plus I-26 is not a major commerce route like I-95.NCDOT's AADT data show 46,000 vehicles on that section of I-26, 17% being trucks. At the Roanoke River on I-95 it's 49,000 and 21% trucks. Comparing volumes, the busiest stretch of I-26 sees 22,000 more vehicles per day than the busiest section of I-95. I-26 isn't a rural mountain drive.

Quote from: CanesFan27 on June 22, 2019, 10:23:36 PMI've had this on my to do list for a long time but I finally have finished a feature on the decade long battle to complete Interstate 95 in Fayetteville, North Carolina.A few things of note:- The appeals came from local businesses along US 301 hoping to route I-95 on what is now Business 95/US 301 in Fayetteville- The case went all the way to the Supreme Court but was not taken.- The I-95 Committee's attempt to find any way (often at the last possible minute) to change the routing.https://www.gribblenation.org/2019/06/governor-hunt-cuts-ribbon-on-doomsday.htmlNice article. I could see most of the existing US 301 route being able to be upgraded to be I-95. Much of it has or had frontage roads which would allow for the upgrade like what will be done for I-42/US 70 in the James City area. The problem area is between Locust St and Grove St. I suppose this is where the compromise route would have used a new alignment. That route would have been ok until the route needs to to be expanded. Expanding the compromise route likely would be much more expensive to build compared to expanding the route that exists now. But I would question whether the compromise route would have been much better than the route that was ultimately built since that too probably would have bypassed the section of highway with the most businesses along it or highest density of businesses. But they would still be much closer to I-95.Here I guessed at the smallest part of the route that would be bypassed.https://drive.google.com/open?id=1cS3AxNGyKWZD2ySzL8nVjBBnrIh8B93F&usp=sharingAnd for giggles I combined that with a connection to make a Fayetteville inner loop.

Most of those were built in the last 20-30 years, a lot the past 10-15.Not to mention, the proposed high-rise Cape Fear Skyway which would be almost 2 miles long, along with the proposed Mid-Currituck Bridge which would build almost 7 miles of bridge over water and swamp.
