Narrative:

Lifted and called tower for clearance through delta airspace direct from position to my destination and was squawking pre-assigned code. [I] received clearance with an altimeter setting of 29.93 at altitude 650 MSL. Three minutes later was crossing extended end of departing runway 17 just south of the highway on a 070 degree heading; when I encountered a cessna taking off runway 17. I evaded aircraft by turning down and to the right as they flew over head about 200 ft above my aircraft. TCAS did not alert me to traffic and did not receive warning from tower. [I] heard over the radio from other pilot that 'he flew underneath me.' I replied: 'saw traffic evaded to the right.' [I] flew through delta airspace without any other occurrence.
