Not sure whether my question can be posted in this forum but here it is..

I am hoping if you could help me join line features by their common attribute. In the example attached below, I have lines with same "PROJECT_ID", TP9N0611. Could any one help me how to join/merge these three lines so that there will just be one line with this id? Some of these lines overlap with each other..  I will have to do this for all other lines that share same project id. Thanks!
