CR 869 was first proposed in 1971 as an alternative to both US 41 and McGregor Boulevard and providing better access to
Fort Myers Beach,
Sanibel, and
Captiva. It was originally planned to be part of SR 869, but the road was never added to the state highway system since it turned over to Lee County before it opened. The SR 869 designation has since been reused for the
Sawgrass Expressway near
Fort Lauderdale. Summerlin Road was originally planned to run through the
Tanglewood neighborhood, but local opposition led to its current route around the neighborhood near Boy Scout Drive. The first segments of the road opened in 1981. In early 1982, Lee County officially gave CR 869 its official name, Summerlin Road. It was named for
Jacob Summerlin, a prominent
Punta Rassa cattleman. The four-lane highway was fully completed in 1983. Summerlin Road was intended to be a
limited-access road, but development along the route has since hindered that intent. To better handle increasing traffic, the intersection with San Carlos Bouelvard (
SR 865) was upgraded to an interchange in 2007 along with being widened to six lanes. Elevated interchange ramps were also added at the Gladiolus Drive (CR 865) intersection at the same time. The College Parkway (CR 882) intersection was upgraded to an interchange in 2011 along with further widening. ==Major intersections==
