East and West Mercer Way Roadside Shoulder Improvements

CM Design Group has worked with the City of Mercer Island to extend the popular bike route that loops around the island via East Mercer Way and West Mercer Way. Working closely with the City of Mercer Island, frequently on compressed schedules, CM Design Group has prepared the PS&E documents for adding a five-foot paved shoulder to the winding and heavily travelled roadway to improve pedestrian and bicyclist safety. In the last eight years we've worked on six phases of the project, covering several miles of shoulder widening.
