A small piece of Parks property that contains one big road sign! This triangle at the corner of 93rd and FDR Drive is nicely landscaped and surrounded by a low, decorative fence, and inside is a large stone monolith that reads "East River Drive Triborough Bridge Approach". This marker is from the 1930s when both the East River Drive (FDR Drive) and the Triborough Bridge (RFK Bridge) were built and is giving drivers some very advance notice that this road leads to the bridge on-ramp at 125th Street, much like the green overhead highway signs do today.
