Reviewed 2026-10-22. Current park profile retains a general area-work notice. The linked project status says soil/grading work has been completed and forecasts the next parking/utilities phase for spring 2027, while older overview text says summer 2026. Those schedules do not certify every area open. The paved perimeter remains the described bicycle course; shorten or postpone if its access is blocked. This is a source review, not a same-day inspection. Recheck the linked manager before travel.
Map and Directions
Use the named public start and its posted parking signs. The map reference identifies the facility or selected trail area; it is not a surveyed parking stall or navigable route line. Bicycle and e-bike rules can differ; only ordinary bicycle use is established unless noted.
