See this post. It was proposed as a free-flowing facility utilizing the existing interchange, but not to have continuity.
The Draft Environmental Impact Statement was released and published on the study website.

As was announced before, the preferred alternative is Alternative C. The total cost estimate is $615,905,708. A detailed breakdown of the costs is located in Appendix E (Page 156) of the Alternative Analysis Technical Report.

The eastern route options initially proposed were eliminated from further study due to the inability to meet the Purpose and Need, due to the fact it would not accommodate regional traffic heading to the west.

The typical section for the new roadway includes two 12 ft lanes in each direction, 12 ft right paved shoulder, and 4 ft left paved shoulder. A 60 ft grassy median would divide opposing directions of traffic. An 18 ft clear zone from the edge of right shoulder to a 2:1 embankment would be required. The minimum right of way for the new location segment would be 168 ft, and 275 ft on the upgraded segment (near the North Carolina state line). The entire project would have full access control with access only permitted at interchanges; at-grade intersections and private driveways would be prohibited. The design speed for the roadway is proposed at 60 mph. Contrary to the typical section diagrams, the upgraded portion near the state line would only have a frontage road on the southern side per the detailed drawings (linked below), not on the northern side.



Interchanges on the new facility would be located at US-220 near the state line, Soapstone Rd, and Joseph Martin Hwy / US-58 / US-220. The southerly US-220 and Soapstone Rd interchanges would be standard diamond interchanges, and the Joseph Martin Hwy / US-58 / US-220 interchange would also be a standard diamond interchange with a flyover and cloverleaf to accommodate movements from the MSC and US-58 / US-220 in both directions. In the Noise Technical Report in Appendix E (Page 180), detailed drawings of the entire project are provided, including the interchange layouts.




As for traffic volumes, the new roadway would carry 10,700 - 11,900 AADT by 2025, and 11,300 - 12,800 AADT by 2040. Truck volumes would be 14 - 16% by 2025, and 18 - 20% by 2040.


Thoughts:

A couple of concerns. First, the design speed for the roadway is proposed at 60 mph, so the likelihood of having a speed limit above 60 mph would be low, maybe 65 mph if it's determined appropriate. In my opinion, this roadway ought to have a design speed of 75 mph. While it is not currently being designed as an interstate highway facility presently, there is a high chance it will be incorporated into Interstate 73 at some point in the future. Per VDOT's Design Standards, a new interstate facility should have a posted +5 mph design speed. In this case, a 75 mph design speed on the Martinsville Southern Connector would accommodate a proper 70 mph posted speed limit.

My other concern is the proposed northern connection with the US-58 / US-220 bypass. To provide maximum continuity for US-220, and in the future potentially I-73 (assuming it will run the MSC and US-220 bypass), the connection should be designed to provide full continuity to/from US-220 to the west and the MSC to the south, with traffic to/from US-58 to the east and Joseph Martin Hwy having to exit right. The southern junction reflects this design, as should the northern one.

I'm betting the owner(s) of those big buildings made a stink about having that access road go right thru all 3, hence the adjustment of the alignment.

Iíve always thought that alignment was poor to begin with. A complex design with decent right of way impacts when thereís plenty of open land to the west to create a rural, simplistic design.

Back in May 2020, VDOT has revised the preferred alternative of the Martinsville Southern Connector project to connect with the US-220 bypass further west of the Joseph Martin Hwy interchange, a location IMO that is more logical and would have less right-of-way impact. It also opens up the possibility to have continuity between the US-220 bypass north and the new Martinsville Southern Connector south.

This new routing will be evaluated in the Final EIS projected to be complete by October 2020.

https://www.virginiadot.org/Projects/Salem/asset_upload_file57_143753.pdf

I would hope that the following changes occur in the Final EIS from the Draft EIS -
- Further west tie in
- Continuity between Martinsville Southern Connector with traffic continuing on US-58 East and vice versa having to exit/enter to/from the right.
- Design speed of 70 mph or 75 mph as opposed to 60 mph to permit a posted 70 mph speed limit.

If this highway is to conceptually become apart of I-73 in the future, these features would be standard on a rural interstate facility, and even though the project is technically an independent arterial bypass, it should be designed to be apart of an I-73 that follows MSC and the existing US-220 bypass north.
VDOT released a new update regarding the projects, indicating that they have submitted a Joint Permit Application (JPA) for the modified preferred alternative of the Martinsville Southern Connector project.

Digging through, I was able to find schematics of the new alignment and how they have decided to tackle the US-58 / US-220 interchange, and it seems they have decided to properly redesign it to include full continuity between the Martinsville Southern Connector and US-220 to the north, with the cross section significantly widening south of the interchange area to match the wide median of the existing US-220 bypass.

With the southern interchange remaining the same, the current design of the Martinsville Southern Connector will have full continuity to US-220 on either end, a bonus if it is to become apart of Interstate 73 in the future to avoid a TOTSO situation.

The only other feature that still has not been updated is the proposed design speed of 60 mph, which would indicate they still intend posting a 55 mph speed limit on this rural, interstate-standard freeway. Specifically, the curve the highway will take to diverge from US-220 on the southern end of the project is designed at 60 mph, not 70 mph. Hopefully this will be addressed in the Final Environmental Impact Statement.
