Florida State Road 390

The western (southern) terminus is at the intersection of U.S. Route 98 (US 98)/SR 30 and US 98 BUS/SR 30A in St. Andrews (part of Panama City).

The highway is carried by Beck Ave from this point until shortly after it crosses SR 368 (23rd St), at which point it becomes St Andrews Blvd.

The route winds northeasterly into Lynn Haven, where it is carried by Tennessee Ave at one point.

In Lynn Haven, the road eventually turns due east and intersects with SR 77 (Ohio Ave), and continues east until its terminus at US 231/SR 75.

This road is now signed as CR 2293 and eventually dead ends east of US 231/SR 75.
