I've never tried this in heavy traffic but I've used:
Alamo [or Alamo Alley] to Clayton/Skinker light into FP
or Demun to Wydown.
I often go straight at Bellevue through Concordia Seminary to Demun & Wydown.
I went straight this morning from bellevue and cut over to demun just before concordia. wasn't sure if going straight thru concordia was an option (and where it would come out on the otherside). Will investigate that this evening if I have time.
All of the streets that cross skinker and have lights , have really long waits. Thinking about one of the streets without a light to make a left onto skinker, but don't know if that would be any faster.
Of course, if I could get out of the house 30-40 minutes earlier, traffic might not be a problem. I'm getting up between 5 and 5:30, like I used to, but now I have to to 30-40 minutes of stretching/strength exercises to keep the heels from barking. Getting up at 4:30 would be really hard.
Yes, the lights are loooong.
OR north on Bellevue or Demun, east on Clayton, then "straight" (actually veer right at AMOCO) at Hi-Pointe onto Oakland or Clayton gets you to Tamm entrance to FP. Clayton-Skinker may offer shorter more balanced lights.
West on Oakland to Skinker is bad in the PM. There are 2 lights, one just before skinker and then skinker. Both are really long.
Crossing Skinker from the park, just N of 40 (Clayton) is a super long light and the cars coming off 40 don't stop when turning N onto skinker. I've had several close calls there. And Clayton road surface is really chopped up from Skinker to Brentwood so that route is way down on the choice list.
I've resigned myself to a long wait at Wydown.
