Annual Mercer Island half marathon set for March 18

The 46th annual Rotary Run may cause temporary road closures and traffic delays.

The 46th annual Mercer Island Half Marathon organized by the Rotary Club hits the streets and trails of Mercer Island on March 18.

This will result in temporary road closures and some traffic delays. Five different run or walk events benefiting colon cancer awareness will take place throughout the morning. Events begin at 7:30 a.m. and end around 12 p.m.; click here for more schedule information.

Mercer Island police, Rotary course marshals and volunteers will provide traffic control throughout the day. Signs will clearly denote detours and areas of temporary traffic delays. Bicyclists and drivers are asked to comply with requests made by race officials.

Residents are advised to use Island Crest Way for North/South travel, if at all possible, and if they must use East, West or North Mercer Way, to travel in a counterclockwise direction to minimize delays.
