I bike over this daily on my way to work. Technically it is not ideal for bikes but the alternative would be biking across North Washington St Bridge (under construction and a death trap for bikers). I think that once the construction for the bridge is complete that would be a better route for the ECG but who knows when the it will be actually complete. For the time being I marked bicycles=yes for this part. Also MassMapper shows this as an existing bicycle trail.
