 The Polk Parkway has become an important part of Polk County's transportation infrastructure as traffic has increased in the growing county.There have been several plans presented to the public since the early 2000s regarding a proposed Heartland Parkway which would be a roughly parkway extending from the Polk Parkway to Southwest Florida near Ft. Myers.There has also been a proposal to construct an extension from the Polk Parkway encircling Winter Haven and connecting with I-4 near the Polk-Osceola county line.
