Narrative:

Departing ord 27L in morning rush. Light transport departed 27L ahead of us. He was given a 220 degree heading. We departed approximately 1 min later on 270 degree heading. At about 1500' we were given a 240 degree heading. Shortly thereafter we were given a heading of 180 degrees. While 1/2 way through the turn we saw the light transport near our altitude at about 11 O'clock and 2 mi. It looked more prudent to steepen the turn and pass behind than to turn back to the right. Departure control then asked what our heading was, told us of the traffic and turned us to 140 degree heading. Frequency congestion may have been a problem.
