Document Description
The proposed project would widen Mirabel Road from State Route (SR) 116 to River Road in Forestville to accommodate Class II bike lanes and northbound and southbound left turn lanes at intersection of Davis Road and Giusti Road as part of the Mirabel Road Widening project. The purpose of this project is to improve the mobility and safety of the existing roadway for all modes of transportation by constructing left turn lanes at Davis Road and Giusti Road intersection and widening the narrow segments of the Mirabel Road to meet the standards of a Class II bike lane. The project would also construct an 8 to 10 foot wide Class I bike path along the east side of Mirabel Road from SR 116 to Davis Road as part of the West County Trail Gap Closure project. Roadway drainage facilities and utility poles will be relocated to accommodate the roadway widening.
