Charleston County Council is considering a proposal to move forward with a controlled access parkway through Johns Island. As proposed, the cross-island parkway would maintain safety for persons living and working on the island and lower vehicular traffic volumes on both Bohicket Road and River Road. In addition, it would help support the rural character of Johns Island and preserve its grand roadway oaks.
A Washington DC based transportation group, TRIP, ranked River Road 5th and Bohicket 6th in a list of the state's 100 most dangerous roads. 28 people died in traffic accidents on River and Bohicket roads between 2002 and 2006. The major problems are the volume of vehicular traffic and the proximity to roadside grand oaks! The slightest mistake leaves no margin for driver error. By 2030, the Council of Governments estimates that traffic volumes will increase 29% on Bohicket Road and 254% on River Road.
A cross-island parkway would be needed to remove 20,000 trips per day from Maybank, Bohicket and River (if built now, it would remove volume of 12,000 trips per day). More importantly, a new road would provide appropriate lines of sight and proper road shoulders, which current roads cannot do, even if County were to build parallel roads to widen existing Bohicket and River. Also, building parallel to Bohicket and River would disrupt and displace far more residents, small businesses and churches than a cross-island parkway through Johns Island.
