Glenn McConnell & I-526 Loop 


Project Description

The Glenn McConnell Parkway/I-526 Interchange Improvement project, located within the city of Charleston, was approved by voters in the second Charleston County Transportation Half-Cent Sales Tax bond referendum held in November 2006.

The project design was approved by Charleston County Council on September 2, 2008. The improvements, which will begin on Glenn McConnell Parkway approximately 2,400 feet west of the Magwood Drive intersection and end at Orleans Road, include: 

  • Widening Glenn McConnell Parkway to provide an additional lane in each direction for the full length of the project.
  • Widening/modifying Magwood Drive’s existing southbound approach toward Glenn McConnell Parkway to provide for two separate left-turn lanes and a shared through/right-turn lane onto Glenn McConnell Parkway.
  • Widening/modifying Magwood Drive’s existing northbound (Hospital access) approach toward Glenn McConnell Parkway to provide for a separate left-turn lane, single through-lane, and right-turn lane onto Glenn McConnell Parkway.
  • Realigning the intersection of Magwood Drive and Glenn McConnell Parkway to allow for concurrent left turns from Magwood Drive onto Glenn McConnell Parkway.
  • Removing the through/left-turn exit from the Lowe’s driveway onto Glenn McConnell Parkway for improved safety.
  • Removing the through/left-turn exit from Charlie Hall Road onto Glenn McConnell Parkway for improved safety.
  • Closing the median on Glenn McConnell Parkway at Frontage Road to prohibit left turns and U-turns for improved safety.
  • Lengthening the dual, eastbound left-turn lanes on Glenn McConnell Parkway that lead to the eastbound ramp onto I-526 in order to allow more room for vehicles waiting to turn left through the intersection.
  • Construct a five-foot-wide concrete sidewalk along Magwood Drive to connect to the existing sidewalk and provide 4-foot-wide bike lanes. Provide sound barriers along the northbound lanes of the Glenn McConnell Parkway to provide a buffer for the Forest Lakes subdivision.
