Highway 85 Road Weekend Closures Continue

Need to travel north or south on Highway 85 from Los Altos, Mountain View, Sunnyvale or Cupertino? Be ready to detour at certain spot beginning as early as 7 p.m. and through the night.

For people who love to hate the bumpy commute on Highway 85, things are about to get a little better, Caltrans says.

But first they have to close off ramps and roadways overnight, in a project that will extend from April to July.

Most lane and ramp closures will begin at 8 p.m. and end before 5 a.m. on weekdays. On weekends, most closures will end by 10 a.m., according to a news release issued earlier this month by Caltrans spokesman Bernard Walik.

For the weekend of May 12-13,  however, the closures are actually an hour earlier and an hour later, according to Caltrans' daily lane closure report made available to the media. 

Lane and Ramp closures, Saturday through Sunday, May 12-13

  • All three southbound lanes closed from the Hwy 101 junction to the Hwy 237 junction, 6 p.m. to noon, May 12-13

The work performed includes grinding existing concrete and replace damaged slabs with rapid strength concrete, a type being used extensively on roadways now for its quick-curing characteristics that allow road surfaces to be operational in a few hours. The shoulders and ramps will get hot asphalt mix. Damaged guard rails are expected to be replaced, as well.

I don't see any 'keep me posted' button... Last night's high-pitched screeching and grinding noises from Mars kept me awake until 2 a.m. How are neighbors expected to survive this ordeal? We have to be able to function the next day. trudysw@sbcglobal.net

So... Can you bring us up to date on this 85 project? Are they doing it in sections or are all of us going to suffer sleep-deprivation indefinitely?

If they post daily updates on construction, why has nothing been updated here since April?

Thank you for the reminders and updates! They help me plan my day!

This is getting really annoying! My house is near the 85 ramp. The noise is so loud and continues to so deep night every day. Even with double paned windows, the noise is driving me crazy. Right now, it is 12am at night, and the noise is still really really loud here. Is it going to be like this until July? Someone may get sick by then and can't work any more.
