Are you West (or South, I guess) of Frisco on 121? If so, you can make a left on DNT before getting to Preston. Or if it is a weekend, you can turn onto Main Street (in The Colony) and go up to Main Street (in Frisco) and avoid most of the mess. If you are East (or North) then I dont know what to tell you.
South. I plan on hooking a left on Main at The Colony and a Right on Main? HITF can you have two Mains intersecting?
