Looks like you did. you can add a little (very little) flux and see if you can build a solder bridge and test continuity again. If it doesn't work try a single strand of copper wire. If that works cover the solder with clear nail polish so that solder will no flow to it when you put in the socket.

Use SIPs or DIP sockets with the high pins http://media.digikey.com/photos/Aries/20-3518-10.jpg so you can set the socket a little high and avoid these traces.

Once these are in test continuity from the repaired trace to the 2 pins that straddle it. There should not be any
