The Mark Clark Extension (MCE), also known as the 526 extension, has been in the planning stages for many years. During this time it has been a contentious issue on Johns Island.
"The purpose of the Mark Clark Extension project is to increase the capacity of the regional transportation system, improve safety, and enhance mobility to and from the West Ashley, Johns Island, and James Island areas of Charleston."
The County must develop a plan to fund their portion of the project and the cost for litigation, bond servicing, and needed improvements to River and Brownswood Roads as well as contingencies for cost overruns. The Joint Bond Review Committee has yet to approve the State Infrastructure Bank to provide the $75M matching funds.
