Edge Lane Roads (ELRs) are also known by the names “Advisory Bike Lanes” or “Advisory Shoulders”. ELRs are a new road configuration which lie between a shared street and standard bike lanes. They allow low-volume roads to be shared by all types of road users in a more equitable and more comfortable manner.

This presentation will illustrate ELR’s decades of use outside North America, their pros and cons, settings in which they can be useful, and an exciting new applications of the ELR format. Information will be shared on the recent use of ELRs in North America, their safety performance here, and the work being done to move them into the mainstream.
