I was looking over the 2015 Capital Budget, and there is a dedicated section to Bike Infrastructure. Listed are the following:
-Central Business District Cycle Tracks (Stanwix Street and Blvd. of the Allies)
-Homewood Cycle Track (Lincoln Avenue)
-Schenley Park Cycle Track (Greenfield Road)
-Pavement Markings on Forbes, One Wild Place, Beacon Street, 40th Street, Marshall Avenue
I assume, "Cycle Track" means a segregated bike lane, if so, this is great news, and is moving towards the better bikeways plan.
Pages 22-23 of the attached document is where this information was found:
