Narrative:
A VFR small aircraft crossed from my right to left in front of and beneath me as I was issued a climb from 6000 to 7000' by our departure. The small aircraft was approach 200-300' above the solid cloud deck--level at 6000', eastbound west/O a transponder on--VFR! I was at about 6300' in the climb when we crossed. Departure was advised of his presence and direction of flight, but was unable to locate him on radar. This is a heavily congested area and incidents of this type are common. This area needs a TCA or an arsa. One comment--this area is the most dangerous corridor in the country. VFR traffic is abundant and many disregard VFR rules or are ignorant of procedures.

Title: NMAC OCCURRED BETWEEN REPORTER ACFT IFR IN CLIMB ON TOP OF OVERCAST AND UNIDENTIFIED VFR ACFT APPARENTLY IN CRUISE.
Narrative: A VFR SMA CROSSED FROM MY RIGHT TO LEFT IN FRONT OF AND BENEATH ME AS I WAS ISSUED A CLB FROM 6000 TO 7000' BY OUR DEP. THE SMA WAS APCH 200-300' ABOVE THE SOLID CLOUD DECK--LEVEL AT 6000', EBND W/O A XPONDER ON--VFR! I WAS AT ABOUT 6300' IN THE CLB WHEN WE CROSSED. DEP WAS ADVISED OF HIS PRESENCE AND DIRECTION OF FLT, BUT WAS UNABLE TO LOCATE HIM ON RADAR. THIS IS A HEAVILY CONGESTED AREA AND INCIDENTS OF THIS TYPE ARE COMMON. THIS AREA NEEDS A TCA OR AN ARSA. ONE COMMENT--THIS AREA IS THE MOST DANGEROUS CORRIDOR IN THE COUNTRY. VFR TFC IS ABUNDANT AND MANY DISREGARD VFR RULES OR ARE IGNORANT OF PROCS.
