The bridges are over lakes & rivers.  Heights range from 100-200 feet depending on water levels which vary by season and rainfall.  You can drive to the bridges, no hiking is involved.

Cost is $99 for 100 ft jump or $149 for 150 ft jump. Normally jumps are done in a body harness which keeps the jumper upright & comfortably supported. Options include: ankle harness ($19), pictures & video ($19/each or $29 for both), GoPro ($29), water dips ($39), BASE jumps ($49) where the bungee cord acts as a backup.
