Since there are some natives who read this blog, I thought I’d list a couple routes to avoid. We travel around quite a bit, so this might be helpful. For everyone else, you can skip this (likely) boring section. This is all for the western part of the island, since that’s where we are at. At some point, I’ll put this info in a different part of the side (off the blog).

• Route 111 is still washed out between Lares on the west and 129 (the east-to-west section) on the east. Coming from Utuado, the detour is 129 south to 128 west to Lares. The detour is clearly marked and heavily traveled. 128 in Lares is a bit slow; lots of switchbacks. Route 111 between 134 on the west and 10 on the east is fine.
• Route 651 between 10 on the east and 651/635 on the west just plain sucks. We tried that route to shortcut between 10 and 129, but it’s very slow and goes through some really seedy areas. I would not drive it at night. I’ve never seen so much garbage around houses and along the roads in all my life. It’s really a shame, because the countryside (in parts) is beautiful. (Now I understand why all the telescope traffic routes further north at 652. Anything marked as a telescope route is safe and cleaned up, from what we’ve seen. The fastest route between 129 and 10 continues to be going all the way up to I-22.
• Route 119 south of San Sebastian to Mariaco is a mess. This is supposed to be a “major” road between the two towns, but is in really bad shape. On the bright side, they are working on huge sections of it. On the not-so-bright-side, the detours, while well marked, put you on very narrow roads. The area is pretty, but the heavily traveled route 2 south is still the fasted way to get to the Mayaguez area.
• The “missing link” between the north end of 10 (Utuado) and the south end (Adjuntas) is still missing. You have to run on old 123, and that road has seen better days. They are obviously not fixing it up at all. On the bright side, they are working on the overpass/bridge towers south of Utuado. So, in our lifetimes, we might actually see 10 connect between Arecibo and Ponce. Note that this missing link is sometimes labeled road 10, sometimes road 123. If you hare heading south toward Ponce, at Adjuntas, just follow the “Ponce” signs to get to where I-10 starts up again. It’s pretty well marked (I think it’s called 5518)–if you see a big plaza being constructed, you’re on the correct road. (It bypasses Adjuntas proper.) 
• Construction of the overpasses on Route 2 between Sabana Grande and Mayaguez and coming along really well, especially on the south end (near San German). These will be a godsend when they are done, since it means fewer stop lights on Route 2. I believe this is all part of the “turning 2 into 22″ plan. They already seem to be making a positive difference. Now if they could only do the same between Mayaguez and Aguadilla….
