20th Street - Marathon

Unlike the section of original Monroe County Road 931 along Sombrero Beach Boulevard, the segment along 20th Street is mostly abandoned, with just a short spur serving just a handful of buildings south from U.S. 1 on Palm Island. The portion along Boot Key is inaccessible as the 1972 draw bridge across Boot Key Harbor was closed by the late 2000s.

Crossing the former Boot Key Harbor draw bridge along 20th Street south. The bascule was removed by the late 2000s, leaving two stubs.

A 30 mph speed limit was posted along all of 20th Street South on Boot Key. Attaining that speed proved difficult on many parts of the roadway due to vegetation overgrowth and pavement ruts.

Boot Key is vastly undeveloped and the east end of 20th Street lied in a forested area. There was no view of Sister Creek or the west end of Sombrero Beach Boulevard.

Traveling back west and north along 20th Street. The majority of the road was relegated to one lane as trees and bushes overtook the road from the outside.

Even on the approach to the Boot Key Harbor draw bridge, vegetation encroached upon the 20th Street right of way. The span was relegated to a 15 mph speed limit.
