UPDATE: Due to on-going construction, and for the safety of motorists and workers, Allen Road (from Busch Forest to the George Winter Park entrance) will be closed to thru traffic for the foreseeable future. Thank you for your patience during this road improvement project.
------------------------------------------------------------------------------------------------------------------------------------------------------
Construction is tentatively scheduled to being on the Allen Road Improvement Project on November 1, 2022. The project limits are from S. Old Highway 141 to the St. Louis/Jefferson County Line and will involve the removal of trees, excavation, retaining wall construction, roadway widening, and repaving.
Due to the narrow and winding nature of the roadway, there will be times of full road closure to thru traffic. The information boards will be updated as needed to inform motorists of closures. A detour route will be in place to direct motorists around the construction.
