Alachua County Board of County Commissioners

DESCRIPTION

The NW 16th Avenue & NW 23rd Avenue project aims to enhance pedestrian safety and accessibility. Key recommendations include widening sidewalks up to 10 feet, restriping travel lanes to 11 feet with a focus on maintaining existing median widths, and adding raised audible thermoplastics on lane markings. Community feedback, gathered during a workshop in December 2010, indicated strong support for safer pedestrian environments. Construction options are discussed with costs ranging from $520,000 to $1,600,000 depending on the scope of sidewalk improvements.
