Island crest way is the largest arterial road on Mercer Island, acting as the largest throughway for people of all kinds on Mercer Island. Although island crest way is a major corridor for people, cars, and busses, it lacks any safe and assessable infrastructure for cyclists, scooters, and mobility scooters, making island crest way dangerous for a large group of residents, including the mobility challenged. why a protected bicycle lane instead of a painted  lane like is used in other major corridors on the island? since island crest way is a major arterial roads, speeds must be kept at acceptable speeds, making an unprotected bike lane a danger to cyclists and vehicles. since island crest way is dangerous for a large majority of people, it is necessary to make a change. change is something that is not foreign to island crest way, in 2012 a road diet was enacted, leading to an over 60% reduction of collisions. if we build a protected bike lane on island crest way from se 40th street to se 68th street we can make another change to save the time and energy of cyclists the island over.
