The proposed typical section along the roadway differs depending on the existing attributes of the corridor, but can be generally divided into two distinct areas.  The two major areas are defined for this project as Maybank Highway from the Stono River Bridge to River Road and Maybank Highway from River Road to Main Road.    

Maybank Highway between the Stono River Bridge and River Road has few driveways and is lined on both sides with grand live oak trees.  To protect these trees, the project proposes to widen from the existing two lane roadway to a four lane divided roadway with a wide natural median.  The wide natural median allows for the protection of the existing grand tree canopy while accommodating the additional vehicular travel lanes.  Driveway access will be maintained with carefully designed median crossings located to avoid impacting the grand trees.  Bicyclists and pedestrians will be accommodated with a proposed 5' sidewalk on the North side of the road and a 10' multi-use path on the South side.  The proposed 5' sidewalk on the North side will be tied into the existing sidewalks which serve Fenwick Plantation to provide continuity for pedestrians. 

Maybank Highway between River Road and Main Road has frequent driveways and the grand trees are fewer and further apart. In this area the project proposes to widen from the existing two lane roadway to a four lane roadway with a raised landscaped median where access conditions permit. Bicyclists and pedestrians will be accommodated with a proposed 5' sidewalk on the North side of the road and a 10' multi-use path on the South side.  Both the sidewalk and multi-use path will be meandered to avoid impacts, where possible, to the grand trees between Main Road and River Road. 

These proposed improvements will allow Maybank Highway to accommodate the existing annual average daily traffic volume of 14,200 in 2006 and the projected annual average daily traffic volume of 39,500 in the design year 2030.
