Q: Do you know if the Caltrans contractor is going to grind/smooth out the new “speed bumps” they installed on Highway 4 between Port Chicago Highway and Railroad Avenue in Contra Costa County? They ground some of the new sections, but some of the uneven surfaces are brutal to drive over in a large truck. I’ve seen front ends implode, trailers come unhitched and loads shaken loose.

Q: I am sure you have traveled up and down Highways 101 and 85 lately and noticed the jungle that is growing in the center dividers on both highways. Since the express lanes are right up against the center divider on 101, these “trees” are growing into the lanes. What can be done about the growth and trash along the center dividers on 101 and 85 in the Palo Alto-Mountain View-Sunnyvale area?
