Protected Bike Lane CAD Concept

I have an existing AutoCAD base drawing of a roadway corridor and need a clear concept plan that adds a protected bike lane along that route. Your task is to work in the supplied DWG/survey file and draft a preliminary layout that shows exactly how the new bikeway will fit within the current curb-to-curb width. The concept must illustrate: • the full lane alignment, • proposed widths for both the bikeway and the remaining travel lanes, and • the type and location of physical barriers or buffers that will keep riders separated from traffic. I want the drawing to read well for non-technical reviewers, so use clean layers, intuitive linetypes, and concise call-outs. A short written note that summarizes design assumptions (design speed, minimum clearances, accepted standards referenced, etc.) will help me present the concept to city staff. Deliverables • Updated DWG file on my title block • A single-sheet PDF plan at 1:500 (or similar) ready for printing • Brief design memo (1-2 pages, Word or PDF) Acceptance will be based on accurate use of my base survey, legible call-outs of every width and barrier, and overall constructability at a conceptual level. If you have experience with NACTO or local bikeway guidelines, please mention it when you respond.
