If they built a bus only road between Hadrian Park and Cobalt where your red line is, the bus companies would be laughing.

It means GNE could divert the 309 through Hadrian Park and into Cobalt that way which removes the need for the 311 going to Hadrian Park. The 310 will still serve the stops at Cobalt South.

Honestly Hadrian Park is probably one of the biggest headaches for bus companies in this area as there is only one way in and out, and to serve it takes around 5 minutes.
