Question:

I have a question and hope you may be able to find the answer. It’s related to the nearly-completed Highway 101 construction north of Santa Rosa.

I drive that stretch of freeway each day to and from work, and have noticed that the pavement underneath any overpass did not get the new surface, and in some areas, the old concrete (pre-construction) is exposed. They painted the lines on the roadway last week, so it appears this is permanent. I am curious as to why they finished the roadway this way. The other portions of newly-widened freeway (Santa Rosa Ave to Highway 12 & Highway 12 to Bicentennial) had new pavement laid under the overpasses.

Answer:

Caltrans spokesman Robert Haus: This is actually pretty common. Many of the overpasses have existing height limitations. A new coat of asphalt would lower those height limits.
You’ll see plenty of overpasses in California in which the pavement underneath is at a lower level.
