Jet route 223 and Victor airway 29
In US airspace, jet routes and victor airways are virtual "highways" in the sky, both made up of predefined, connecting radials off VORs. Victor airways are low altitude airways, or airways meant to be used at or below 18,000 feet, that are found on the low altitude en route IFR charts while jet routes are airways meant to be used above 18,000 feet and are found on high altitude en route IFR charts.
Here's the relevant screenshot from a high altitude IFR chart showing J223 and CORDS:
