U.S. 17 Hampstead Bypass in NC
« on: June 29, 2017, 12:03:29 AM »

What is the purpose of this bypass? It is proposed to run from I-140/US 17 Wilmington Bypass and future Military Cutoff Road extension just north of Wilmington to US 17 north of Hampstead.

Is the state still trying to turn U.S. 17 into a interstate? There are already interstate standard bypasses for Jacksonville, New Bern (co-signed with US 70/Future I-42), Williamson (co-signed with US 64/Future I-87) and Elizabeth City (future I-87), The Maysville and Pollocksville bypass that is currently under construction will be built to interstate standards (except for each end of the bypass) but of course is what is coming is the future I-87 in the future that will mostly use existing US 17, which obviously will have to be widened to interstate standards.

I don't live in that area so hopefully someone will tell me if they know something about it.

The only part of US-17 that is planned to become an interstate is the part that will be I-87. NCDOT does want to eventually upgrade US-17 to a freeway through the whole state, though. The section of US-17 that is co-signed with US-70/Future I-42 near/in New Bern does not yet meet interstate standards due to narrow shoulders. Only the part between US-70 and US-17 Business west of New Bern is interstate standard. That bypass will eventually be extended north to connect with US-17 north of New Bern, so the US-17/US-70 concurrency is only temporary.

It's been many years since I passed through Hampstead, but I remember traffic being pretty bad there, especially during the summer months. The Hampstead Bypass could become an eastern extension of I-140. The section of the Wilmington Bypass east of I-40 is not yet part of I-140, so this could explain why. NCDOT has made no mention of any eastward I-140 extension.

^ Following FHWA general criteria for "logical termini" for Interstates, such an extension would have to reach at least NC 172 (if not all the way to Jacksonville) before it could become an Interstate.

I don't think the Hampstead Bypass will be a part of I-140. I do know it is planned to be a part of US 17. I-140 is proposed to extend east to end at US 17/US 17 Business northeast of Wilmington provided that the route is approved.

I don't live there either, but I passed through the Wilmington area this weekend going between the Baltimore, Maryland area and Myrtle Beach, and I'm really hoping for the Wilmington Bypass to be fully open as soon as possible.

Resurrecting this thread so this doesn't get buried in the general NC thread:


This video was uploaded recently showing what I imagine is the latest preliminary design. The northern terminus has been revised to a simple trumpet interchange, with the bypass having continuity. The previous design still on the project's site is a weird hybrid left-exit thing, and the earliest design I saw had two separate trumpet connections at the northern end (see sheets 5 and 6), while this latest design only has one.

^ I saw that a few weeks ago, and am glad for the change.

The I-140 connection still lacks continuity, but at least they got it right here.

The original proposed one was just a confusing cluster of ramps and signals that was unnecessary.

The new design also extends the freeway / limited-access design an additional 2,000 feet northwards, and if NCDOT decides to later upgrade the rest of US-17 up to Jacksonville or Pollocksville to interstate standards, it makes it a lot easier of a transition, notably with the extended southern frontage road. Though with the urban superstreet design with sidewalks and curb / gutter extending another mile northwards, who knows.

They changed that to a trumpet interchange? That's a very good move. It's more of a freeway than an expressway look.

I think I still like the oldest (two trumpets) interchange design. But they probably didn't do it because you would have to make an extra right turn (which is no biggie). But still, I think the very first alternative was the one to go IMO. I'm not sure if they would bring that alternative back.

Alternative 1 (two trumpets) Best IMO

Alternative 2 (hybrid left turn) Bad

Alternative 3 (one trumpet) Adequate

I fail to see how the original proposal with two trumpets is better than the latest with one. Itís overbuilt and unneeded IMO.

Just like they removed the loop on the NC 210 interchange. And (This is the SW bypass old plan) a bigger road at Davenport Farm Rd when it joins US264A/US13. And for the exit ramps have 1 lane split in to 3 and 4 at US 13 and US 264A.

Also, the NC 140 interchange at the military cutoff extension used to have 3 flyovers proposed.

I can't find the link but i know it used to be 3 flyovers and it was from 140 eastbound to military cutoff rd (southbound).

So that's the reason you think why the very first alternative (2 trumpets) is better than the latest one with one trumpet? Because people would have to make many turns and that's all.

Are the traffic demands heavy enough to warrant two trumpets?

I guess not and that first design was a little weird. I'm glad they changed it.

Any updates on the Military Cutoff Road project? I haven't seen anything on that project in a while.

According to the NCDOT project site:
https://www.ncdot.gov/projects/us-17-hampstead-bypass/Pages/default.aspx

The Military Cutoff extension project should be completed in the spring of 2023, the US 17 Bypass part of the project won't start until late in 2022.

Don't want to start a rant about this discussion again, but the first alternative with 2 trumpets was definitely better than the hybrid left turn (alternative 2).

Also, an advantage for alternative 1 is also hiding the schools in an area so it's not so busy.
