NORTH PARK ROAD IMPROVEMENTS – JAMES WATTERS The detour of N Park Rd for through traffic was placed on April 28th. MSA and City have been in coordination with CCA schools who have issued newsletters to parents informing them of the upcoming detour route. Following feedback on the function of the closure, additional signs have been added along Highway 6 to indicate that North Park Road is closed. Staging sheets (J.01 to J.101) have been reissued to reflect the new staging plan. This splits the project into three stages (stage 1 has two substages). The whole of Stage 1 is expected to be completed this Summer. Stage 2 will begin after school is back in session. The section of North Park Road from the school bus loop to the Oak Hill Elementary entrance has been closed for Stage 1A. Excavation, placement of the pedestrian underpass, additional storm sewer and water main are anticipated to begin in late May. Stage 1B closures just south of Oak Hill’s entrance and just north of Tiffin Elementary’s entrance will take place on June 2nd, 2025. This date has been confirmed as an acceptable closure date by the Clear Creek Amana Community School District. PROJECT UPDATE Page 1 of 3
