I just drove the entirety of AL 158, which now extends all the way west to a junction with US 98 0.7 mile east of the state line. I didn't take photos because it was rainy, but I did note some approximate points for the eventual log:
0.0 - split from US 98
2.3 - drops back to 2 lanes (westbound roadway appears years from completion)
4.1 - CR 63 Wilmer-Georgetown Rd (separation with ramp, similar to AL 217)
9.4 - Stone Rd (at-grade intersection)
10.4 - ramp to AL 217
10.7 - crossover of AL 217
11.9 - resumes 4-lane configuration
12.2 - CR 31 Newburn Rd (current western terminus in TM)
Hope this helps.
