Narrative:

I received a departure clearance from clearance delivery for a VFR flight (part 91) to kingman, az. I then called ground control for a taxi clearance. He cleared me to taxi to runway 19R. The controller asked me to read back my runway assignment and I confirmed, 'taxiing to runway 19R.' as I approached the approach end of runway 19R, I requested takeoff clearance. The tower controller cleared me to 'cross runway 19R and taxi into position and hold runway 19L.' I read back this clearance and complied. I was in position on runway 19L for about 1 min. I was then 'cleared for takeoff runway 19L, caution wake turbulence from departing aircraft runway 25.' I read back my takeoff clearance as 'roger, cleared for takeoff runway 19L.' on takeoff roll, at about rotation, I observed apparent aircraft movement to the left of runway 19L at an intersection directly in front of me. As I continued my climb over that intersection, I observed a taxiing aircraft completing his movement across runway 19L. I informed the tower controller and he gave me a phone number to call and told me to 'turn to a heading of 175 degrees and contact departure,' which I did. No evasive action was taken (or necessary) on my part to avoid the intrusion. It is my guess that I passed over that intersection at about 200-400 ft.

Title: ACFT #1 (ACFT X) WAS CLRED FOR TKOF ON RWY 19L. AT THE SAME TIME ACFT #2 (ACFT Y) WAS ALLOWED TO TAXI ACROSS RWY 19L. THIS ACTION RESULTED IN AN NMAC BEING FILED.

Narrative: I RECEIVED A DEP CLRNC FROM CLRNC DELIVERY FOR A VFR FLT (PART 91) TO KINGMAN, AZ. I THEN CALLED GND CTL FOR A TAXI CLRNC. HE CLRED ME TO TAXI TO RWY 19R. THE CTLR ASKED ME TO READ BACK MY RWY ASSIGNMENT AND I CONFIRMED, 'TAXIING TO RWY 19R.' AS I APCHED THE APCH END OF RWY 19R, I REQUESTED TKOF CLRNC. THE TWR CTLR CLRED ME TO 'CROSS RWY 19R AND TAXI INTO POS AND HOLD RWY 19L.' I READ BACK THIS CLRNC AND COMPLIED. I WAS IN POS ON RWY 19L FOR ABOUT 1 MIN. I WAS THEN 'CLRED FOR TKOF RWY 19L, CAUTION WAKE TURB FROM DEPARTING ACFT RWY 25.' I READ BACK MY TKOF CLRNC AS 'ROGER, CLRED FOR TKOF RWY 19L.' ON TKOF ROLL, AT ABOUT ROTATION, I OBSERVED APPARENT ACFT MOVEMENT TO THE L OF RWY 19L AT AN INTXN DIRECTLY IN FRONT OF ME. AS I CONTINUED MY CLB OVER THAT INTXN, I OBSERVED A TAXIING ACFT COMPLETING HIS MOVEMENT ACROSS RWY 19L. I INFORMED THE TWR CTLR AND HE GAVE ME A PHONE NUMBER TO CALL AND TOLD ME TO 'TURN TO A HDG OF 175 DEGS AND CONTACT DEP,' WHICH I DID. NO EVASIVE ACTION WAS TAKEN (OR NECESSARY) ON MY PART TO AVOID THE INTRUSION. IT IS MY GUESS THAT I PASSED OVER THAT INTXN AT ABOUT 200-400 FT.
