Lee’s Summit Road between Colbern Road and Gregory Boulevard is now expected to remain closed until spring 2016 due to several delays during phase 1 of the Lee’s Summit Road Improvement project.  The overall project is still anticipated for completion by the end of 2016. Phases 1 and 2 of the Lee’s Summit Road Improvement Project were originally anticipated to be completed by November 2015, with Lee’s Summit Road reopening before winter. However, the approval process for certain construction materials caused by the inclusion of federal funding and issues with a waterline design created delays in phase 1 of the project. The revised project schedule extends construction on phase 1 until at least the end of the year, and phase 2 through spring 2016. Phases 1 and 2 of the project cannot be completed at the same time; working on both at the same time would close all access to Douglas Street for businesses, residents and the Lee’s Summit Municipal Airport. The most critical event in the revised phase 1 construction schedule is installing fly ash for the soil stabilization under the new road, which is tentatively scheduled for mid-November. Fly ash requires a minimum ground temperature of 40 degrees for installation, and an air temperature of 40 degrees for curing, so suitable weather days in November may be limited. In the original project schedule, the fly ash and asphalt should have been completed by mid-October when the temperature requirements are less of a concern.  The fly ash is scheduled to be followed by an asphalt base in late November, and then concrete drives, sidewalks and restoration through mid- to late-December. If weather conditions are not favorable, phase 1 construction could be extended until spring 2016.  Additional Information...
