Interstate 87 (NC-VA)

[jcil4ever]

Turns out they have begun shoulder widening as part of the repaving work near Nashville. So far the construction has involved shoulders west of NC-58 (Exit 459) east and westbound. I didn't catch where the work began/ended on the western end, but I think it's tied to the current repaving. The press release also does mention shoulder reconstruction.

Westbound between NC-58 (Exit 459) and US-64 Alt/Bus (Exit 458):

It's unfortunate the Interstate 87 designation won't go any further east anytime soon: https://www.malmeroads.net/ncfutints/fut87.html.

The NCDOT traffic advisory for the project indicates the right lanes are closed between MM 459 and 455 for the next 2 weeks. The project's western extent is Old Franklin Road, Exit 453, the eastern at Old Carriage Road, Exit 463. Will be interesting to see if the shoulder widening extends to either end.

US-17 exists as a limited access roadway in Virginia with a number of rural at-grade intersections, two signalized intersections, and 3 interchanges. The northern 3 miles is already built as a freeway. That area is currently growing. I think it's more likely US-17 is upgraded over the next couple of decades in piecemeal fashion (interchanges replacing the signalized intersections first, for example) as growth creeps south. The remaining intersections can be dealt with in a single project with an interchange or two and an overpass or two... maybe a frontage road somewhere for local access.
The difference is Virginia has a framework, they have the main highway built - and it has access control. It's just missing a few interchanges and finishing touches.

I went back and found where I analyzed this in depth -- upgrading US-17 in the City of Chesapeake to Interstate highway standards.

Actually it would be an involved and expensive project. Low priority for Norfolk/Hampton Roads. Existing highway works very well.

Key excerpts:

Post #1002, Feb. 2019

Mr. Cartwright's farm [he still owns it] has property on both sides of US-17, it was divided by the relocation project, and he has 3 at-grade intersections [and a 4th near the state line] with breaks in the limited access right-of-way line, they provide him access across the highway as well as to the highway.  VDOT can expect some serious legal opposition if they try to take a major chunk out of his farm, plus serious acquisition expense, so I don't see that is being a feasible alternative.  With most farm equipment you can't accommodate that on a one-lane bridge, so figure a 2-lane bridge with gradual enough earthen roadway approaches so that heavy farm equipment can make it up the grade.

A location/EIS study and public hearings and city resident input would most likely result in at least 5 new public road interchanges, and at least 4 new overpass bridges with no interchange.

There are several ways to address the Cartwright Farm, the least expensive way that also gives him full access to his farm and full grade-separated access to US-17 at about the midpoint of his farm, would probably be to build a private paved service road for 3 miles (yeah, that is how big his farm is!) along the east side of the highway and to build a diamond interchange near Number Two Ditch and it would be for his private use.

A basic freeway interchange with a local road would be about $25 million in today's dollars, just for construction.  The overpass without interchange on level terrain would require earthen roadway approach to meet grade and this would be about $10 million in today's dollars, just for construction.

So that is 6 interchanges and 4 overpasses, or $190 million in today's dollars, just for construction.  Maybe 5 miles of 2-lane service road at $10 million total, now up to $200 million total.

Design engineering and construction engineering together are budgeted at 15% of construction costs, so $30 million for that in today's dollars.

Right-of-way costs would be dependent on the final design and the lands impacted, but for the above I don't think it would be less than $20 million.

So that is $250 million, in today's dollars (in a state or local TIP it would be inflation-factored thru the various budget years).  That $250 million would be a good starting point at this time, naturally it would take preliminary engineering studies and design reviews to come up with a detailed estimate.


Post #1008, Feb. 2019

Here is what happens with my US-17 preliminary estimate which is in -today's- dollars, into what might be a realistic timespan to build it --

$250 million in 2020
Inflation-factored to 2030-2035 program funding
5% per year ------ $473 million
8% per year ------ $668 million
10% per year ----- $848 million

10% average per year cost inflation for heavy construction, is actually rather typical, and some years are worse.  So a properly programmed STIP or MPO long-range plan should IMHO utilize at least 8% per year in the out years on average, although on a plan with a 20-year horizon such as a 2040 plan, I would strongly recommend using 10% per year.

This of course is not a professional estimate, but it is certainly reasonable.

I'm confused which section of farmland you are referring to.

The farmland on either side of US-17 between the North Carolina state line and Ballahack Road is owned by Frank T. Williams. Additionally, the southern mile or so has been subdivided from the main tract and the city has been pursuing it for the development of a mega site known as the Coastal Virginia Commerce Park.

https://www.cityofchesapeake.net/573/Coastal-Virginia-Commerce-Park-Formerly-

Two years ago, the city approved the development of the park and implemented a plan for a grade-separated interchange to be constructed at this location, approximately one mile north of the state line. This interchange must be constructed prior to any development occurring on the site.

And the city (Chesapeake) is planning a mega site development near the North Carolina border, with the prospect of the interstate running alongside it in mind, but is planning to construct an at-grade signalized intersection on rural US-17 using one of the authorized breaks in limited access right of way currently used for farm access.

City Council approved this development last month and according to the latest report, the plan now calls for a grade-separated interchange to be constructed along US-17 for this "megasite" development. This would be located within the first mile or so of US-17 in Virginia just north of the North Carolina state line.

The following improvements will be provided as part of this development:

I. Primary Site Access- A grade-separated interchange will be constructed for the primary development access off Route 17. The final location will be approved by the City and VDOT to insure spacing of roadways consistent with access management plans and principles. These improvements will be constructed and operational prior to the first certificate of occupancy within the development unless approved otherwise by the Director of Development and Permits as a result of an approved TIA. The interchange will include the following:
            i. Sufficient number of lanes on the overpass (grade separation) to provide a LOS D or better.
            ii. Ramp lane quantities, Route 17 mainline diverge and merge lane lengths, and geometry in accordance with a City approved TIA and VDOT criteria. 
            iii. Signalization at the intersection of the access road overpass and the southbound on and off ramps as warranted.
            iv. Accommodations for pedestrian access and connectivity to the greatest extent possible.

In the event you are referring to this tract, south of Ballahack Road, access to the western 220 acres would be made via an interchange at Ballahack Road, and the old alignment of US-17. While mainly a pedestrian / bicycle trail, small portions remain open for local access. This would be the same.

If that access was an issue, the city or state also has the option to buy that portion of farmland out entirely. It is only valued at $858,000, far less expensive than any overpass bridge would cost.

Here is a link to the city's property map.

--

As far as "Cartwright", the only farmland owned by him is between Glencoe St and Ballahack Rd. The eastern side has access provided by Belle Haven St. The western side could similarly be provided access by old US-17, with an interchange at Ballahack Rd, or if access is a concern, could be bought by the city / state. The western 129 acres is valued at $854,000, far less expensive than any overpass bridge would cost.

I'm not sure where a $25 - $30 million price estimate is coming from regarding two tracts that are valued around $1.7 million total.

The NCDOT traffic advisory for the project indicates the right lanes are closed between MM 459 and 455 for the next 2 weeks. The project's western extent is Old Franklin Road, Exit 453, the eastern at Old Carriage Road, Exit 463. Will be interesting to see if the shoulder widening extends to either end.

A new travel advisory has the right lane closed on US 64 West from MM 457 to MM 453 for the rest of the week. Hopefully, shoulder widening is to go all the way to the Old Franklin Road exit.
