Closure Schedule

  • Westbound closures will occur weekdays 12:00 Noon – 5:00 AM
  • Eastbound closures will occur weekdays from 8:00 PM – 12:00 Noon

Caltrans said the lane closures to correspond with the lighter traffic on reverse commutes. One lane will always be open in each direction during closure hours.

Ghilotti Brothers of San Rafael is the contractor on the $2.1 million project, which is expected to take one month to complete. During the project, the top layer of asphalt will be ground from the pavement and replaced with a fresh layer of rubberized asphalt.
