CHALLENGES

• Before 1962 Folly Road was two lanes

with a 50’ ROW, then SCDOT expanded to a ~70’ ROW

• Generally 35’ feet along the west side
• f Folly Road
• 32.5’ pavement
• 1.5’ curb & gutter
• Approximate cost of ROW purchase =

$40/sq. ft

• Utility poles are a major challenge along the

corridor for each alternative

• There will not be a significant impact on below

ground utilities

• Telephone pedestals, gas monuments,

backflow preventers would need to be relocated

• Existing site drainage would be impacted for 3

businesses

• Eliminating existing bike lane requires

upgrades to Folly Road drainage system

• Most businesses along Folly Road have

signs that are typically at ROW edge

• Signs are expensive and difficult to

relocate

• Relocation Costs:
• Monuments signs: $10,000
• Post signs: $5,900
• Traffic signs: $500

Future Bike Improvements

Install 8’ sidewalk at back of curb & relocate overhead power lines (approx. 2.1M) Restripe Folly Road & paint bike path to provide proper bike path width (approx. $400,000 - $1.1M) Request SCDOT perform a speed study to lower the speed limit
