Mosquito Road is anticipated to be closed to through traffic beginning approximately July 5, 2022 and ending approximately August 8, 2022. Closure limits are anticipated to coincide with the current gate locations and will be coordinated with schools and emergency response as needed. Intermittent lane closures and flagging should also be anticipated as needed for mobilization of construction equipment and materials. During this time, it is also anticipated that tree removal operations will occur for the bridge project, and routine maintenance of existing Mosquito Road Bridge will also be conducted. For additional details refer to the PCMS boards located along the roadway and to this project website.
