Grissom Parkway between 10th and 21st Avenues North in Myrtle Beach

Robert M. Grissom Parkway, locally known as Grissom Parkway, is a major four-lane connector highway in Myrtle Beach, South Carolina. It goes from Carolina Bays Parkway across the Intracoastal Waterway to Harrelson Boulevard near Myrtle Beach International Airport. It provides access to Myrtle Beach attractions such as Coastal Grand Mall, Coastal Federal Field and Broadway at the Beach and is used as an alternative road to U.S. 17 and Kings Highway in Myrtle Beach. It has bike paths and sidewalks for pedestrian traffic.

When the road was completed, it replaced Old Socastee Highway between Pine Island Road and U.S. 501 as well as Central Parkway at Broadway at the Beach between 21st Avenue N. to 29th Avenue N. Since 2006, the intersection with 21st Avenue N. has been the start line for the annual Bi-Lo Marathon.
