I-15 Bridge Work over Santa Ana River: Construction crews are performing soil testing underneath the bridge, requiring use of a boring rig that will drill holes at various locations underneath the bridge to gather soil samples. The work is taking place 7 a.m. to 5 p.m. weekdays and is expected to last through September. The work is necessary to accommodate the future widening of the bridge, as part of the I-15 Express Lanes Project. Some noise is expected, but it will not exceed levels permitted by local, state, and federal regulations.

Project Work: Surveying and underground utility locator crews will continue working throughout the project limits on shoulders, under bridges and around on-and-off ramps. This work is required to verify locations of existing underground utilities and physical properties which could affect elements of the project design.
