I had the opportunity to drive the section from I-22 to MS 302 this evening. Nothing terribly exciting to report, although the control city southbound/westbound is covered up on the signs at the I-22 interchange; as expected, the northbound/eastbound control city is Collierville. There wasn't much traffic - not surprising, since this section isn't terribly useful for traffic not headed to Collierville or other parts of east Shelby County.
Also, while I-269 does show up on Google Maps, the routing engine on their Android app doesn't yet think it exists - although it works fine in Waze.
