A reconfiguration of the intersection of Grand Island Boulevard and Staley Road gets underway on Grand Island on Monday. The traffic signal there will be replaced with a roundabout. The intersection will remain open throughout the project, but trucks will not be allowed to use exit 18 off Interstate 190 northbound, and part of the South Parkway multi-use trail will be closed. Detours will be posted. The construction is expected to take several months.
