The remaining portions of Willow Road bridge at U.S. 101 will start being demolished Monday, October 5, at 9 p.m. and the freeway will be closed overnight. Caltrans must perform the work at nighttime because demolition of the bridge deck, columns and abutments cannot safely be performed while U.S. 101 is open. High traffic volumes preclude full closures of the freeway during the day.
The demolition is expected to be noisy, but the construction team has made changes to the demolition process to help reduce nighttime noise and perform some of the activities during the day. The demolition work is expected to continue through the end of October 2018.
The modified demolition method includes sawing the existing bridge deck into pieces, then removing them using special equipment. The previously used method involved using large air-hammers to break up the concrete, which created loud and constant noise during demolition activities. While this modified method does not eliminate air-hammering completely, it does greatly reduce it.
If you have any questions or concerns about the project, please contact the Caltrans Public Information Officer Jeff Weiss
