In addition to the projects listed below that may impact your commute, you can find information on work being done to enhance our City on the Capital Improvement Projects Map and the Road Construction Map.
I-5 Full Freeway Closures
As part of the Jeffrey Open Space Trail Bicycle and Pedestrian Bridge project, the I-5 Freeway will experience full overnight closures over two weekends. Please see details below.
The work being done includes erecting falsework steel beams and plywood forms over and across the freeway. It will generate construction noise, including equipment backup alarms and heavy equipment engines, and additional lighting may be required. The Jeffrey Open Space Trail Bicycle and Pedestrian Bridge is expected to be completed in March 2026.
