As of late 2019, there is a "cycle and pedestrian only" path parallel to this frontage road.  The path extends south from the intersection of Roseville Court and Broadway Avenue; it ends at Pershing Avenue, just east of the intersection with East 45th Street.  The path is just west of the frontage road.  
(There are plans to extend the path beyond this segment, but this is the limit of construction as of August, 2020.)
It's called the Slavic Village Downtown Connector Trail.
