CONSTRUCTION NOTICE: I-15 Bridge Over the Santa Ana River


Construction crews will continue soil testing underneath the bridge. This work requires the use of a boring rig that will drill holes at various locations underneath the bridge to gather soil samples. This work is necessary to accommodate the future widening of the bridge, as part of the 15 Express Lanes Project.


Late July 2017 through September 2017, weekdays from 7:00 a.m. to 5:00 p.m.


The use of the rig will require the short-term use of the horse trail to move the rig down under the bridge. Some noise is expected, but it will not exceed levels permitted by local, state, and federal regulations. Flaggers will be onsite to direct construction crews, equipment, and trail users. Access to the trail will be maintained at all times.
