Bohicket Road

Betsy Kerrison Parkway

No improvements are planned by the County.  The only improvements that would occur are those that would be required by SCDOT for new developments, e.g. turn lanes.


Note that the Town of Kiawah has envisioned a stoplight at Camp Care Road for access to an envisioned development across Betsy Kerrison Parkway.


Kiawah Island Parkway

The Town of Kiawah Island has done an analysis of traffic on Kiawah Island Parkway.  Note that the Parkway, as well as the Freshfields Roundabout, are owned by the Town.  The analysis can be found at:

Betsy Kerrison Parkway

Main Road Corridor Project

The upgrade to Main and Bohicket Roads was part of the 2016 half-cent sales tax referendum.  The referendum was codified in an ordinance which you can view here.  The ordinance states in part that projects "may include, but [are] not limited to ... US 17 at Main Road flyover and widening Main Road from Bees Ferry to Betsy Kerrison with Parkway type section at Bohicket“.  These funds are referred to as Transportation Sales Tax (TST) funds.


The Main and Bohicket Roads upgrade project, referred to as the Main Road Corridor Project, was approved and funded ($195M) by Charleston County Council in May, 2018.  You can view the sign-off sheet here.  Council also separated the project into three segments and prioritized them as follows:

  • Segment A:  Main Road from Bees Ferry Road to River Road
  • Segment C:  Bohicket Road from Maybank Highway to Betsy Kerrison Parkway
  • Segment B:  Main Road from River Road to Maybank Highway


In July 2020 the State Transportation Infrastructure Bank (STIB) provided "$40.7 million in funding to go toward the $111 million [Segment A] project.  The county will fund the rest of the project with half-cent sales tax money."  See this article.


Cost Estimate
The original cost estimates totaled $165M to $205M.

  • Segment A:  $85M to $105M
  • Segment B:  Not included
  • Segment C:  $80M to $100M


The current cost estimates are:

  • Segment A:  ???
  • Segment B:  Not included
  • Segment C: $40 to $200M (Alternative dependent), revised April 2022


Funding
The currently available funding is $195M from TST funds allocated to the entire project and $40.7M of State Transportation Infrastructure Bank (STIB) funds which can only be used for Segment A, for a total of $235.7M.   Construction must start on Segment A by ??? or else the County will lose these funds.


Segment A
You can view a map of Segment A here.


Segment B
Inactive


Segment C
"The primary purpose of the project is to reduce congestion (see projected traffic data) and to increase capacity on Main Road/Bohicket Road from Maybank Highway to Betsy Kerrison Parkway.  The secondary purpose of the project is to provide opportunities for bicyclists and pedestrians to safely travel throughout the project area."


There are currently six alternatives still being evaluated.  You can view maps of each of these alternatives here.


  • Alternative 1:  Widen Bohicket Road from Betsy Kerrison Parkway to Brownswood Road


  • Alternative 1A:  Widen Bohicket from Edenvale Road to Brownswood Road


  • Alternative 3:  New road through the center of the island from Betsy Kerrison Parkway to the proposed Mark Clark Extension


  • Alternative 4:  Widen Bohicket Road to north of Edenvale Road then a new road to the proposed Mark Clark Extension


  • Alternative 6: Selective improvements on Bohicket Road from Edenvale Road to Chisolm Road and add road network


  • Alternative 7:  Widen Bohicket Road from Edenvale Road to Brownswood Road, widen Plow Ground Road, and widen River Road to Maybank Highway


Note that Alternatives 3 and 4 do not make any improvements to the Maybank/Main/Bohicket intersection and that alternatives 3, 4 and 7 make improvements to River Road north of Plow Ground Road.
