Resolution to Approve City of Ann Arbor - Michigan Department of Transportation Agreement No. 10-5159 for Improvements to Plymouth Road (Nixon Rd. to US-23) and Green Road (Plymouth Rd. to Baxter Rd.)

They include milling the existing asphalt surface, repairing the underlying pavement and roadway base, removing and replacing sections of concrete curb and gutter, repairing storm sewer catch basins and placing a new asphalt surface. On Plymouth Road a special treatment designed to help retard cracking will be applied before the new asphalt pavement is placed.
