As you begin travel on Vanderbilt Beach Road, east bound from Airport Pulling Road, you will observe a 45mph speed limit sign, in less than a quarter mile it drops to 35 on a portion of roadway which was recently widened and repaved and clearly suitable for 45mph. After crossing Livingston Road it goes back to 45. The presumption is that construction is ongoing, however none is observed and the speed enforcment has been massive.
