Narrative:

The knik 2 departure has a left hand turn to 329 after 2000 or 4 miles; whichever occurs first. During the climb out off of 07L; right before the turn; we receive a traffic alert and I see traffic on the magenta line on the nd at our altitude. He was right where we were about to turn into. We were cleaning up and believe we were at flaps 1. Rather than lower the pitch to accelerate; I kept the pitch attitude to maintain a better climb; increasing it a little. We see the traffic cross to the left and below as we then start our turn. In the middle of the turn departure control queries if we are in the turn. The first officer responded we are in the turn; traffic insight; even though the controller did not call it out. Looking at the nd it appeared that we were on course. After rolling out on the heading; we received a traffic alert for another aircraft from ATC. Due to the mountains; there is a lot of VFR traffic that flies in the corridor between the mountains and the airport. It is distracting for crews to have VFR traffic during the climb out located on the assigned departure at or near the aircraft altitude. My recommendation would be for anchorage tower not to issue a takeoff clearance when traffic will conflict. There have been many instances in anchorage where we will pass over traffic with minimum separation and during a climb with a high-power setting. Being that this is a heavy aircraft that is very dangerous for a single engine airplane with regards to wake turbulence.
