The county's original plan has left residents with mixed feelings.
Some argue that the improvements could help save lives, while others complained about noise from the audible speed strips. One resident compared the potential noise to the sound of a machine gun.
Dropping the speed limit to 25 mph, making it a toll road and calling for more law enforcement presence along the drive all were suggestions residents urged the county to consider.
A few people, desperate for more law enforcement, said they would pay $45 an hour for off-duty deputies to patrol Indian River Drive.
County Commissioner Cathy Townsend, who opposes the audible strips and other improvements, said she now wants to spend some of the county's original $750,000 allocation on SkyCop, a Memphis company that mounts cameras to utility poles to monitor traffic and collect data for law enforcement.
