A piece of HWY 138 from the 15 freeway to Lake Silverwood and beyond is being realigned and will go away forever. I read that they had approved the work but I had no idea it had begun and had gotten so far. Looking at Google Maps newest imagery for all I know it's already gone. They've already wiped out the wicked hairpin. If you happen to be in the area of the 15 freeway in the Cajon pass I'd hit it one last time for old time's sake. It's a very tight technical rollercoaster piece of road. Not as long as some of the best roads around but very very good. If you decide to make a drive out of it (the disappearing section is only 1 mile) continue on past Silverwood up to Crestline. The bit that leads you up from the lake is also very good. Be careful - both sections can be tricky. Stay safe out there.
