Construction Activities Under Jamboree Road/I-5

Construction activities are expected to take place under the Jamboree Road/I-5 bridge. Crews will carry out daytime pile driving activities for abutment work and nighttime cast-in-drilled-hole (CIDH) activities for bent work for the widening of I-5. *See diagrams below for more information on pile driving, CIDH, abutments, and bents.

Anticipated Dates: As early as May 18 and continuing for several weeks.
Anticipated Pile Driving Daytime hours: As early as 7 a.m. to 4 p.m.
Anticipated CIDH Nighttime hours: As early as 10 p.m. to 5 a.m.

Additionally, CIDH nighttime work will require long-term lane closures:

• Crews will close off the lane closest to the median in both directions of Jamboree Road at the I-5 bridge with concrete barriers. At least one lane in each direction will be open to traffic at all times, unless otherwise specified.
• Lane closures will be in place for initial CIDH construction activities and remain until late 2026 to support additional I-5 widening work ,including:
• Set-up of falsework (temporary supports that keep a structure stable during construction until it's finished)
• Placement of rebar, concrete, etc., for the new bridge columns

Finally, CIDH nighttime work and other ongoing nighttime activities may require intermittent full street closures of westbound (WB) and eastbound (EB) Jamboree Road at I-5 throughout the life of the project. Please see below for closures and detours maps.

This work may be loud. The schedule is subject to change due to inclement weather or unforeseen operational issues.
