In addition, a privacy fence is being installed along Longworth Avenue, adjacent to northbound I-5 freeway. This work will be conducted weekdays, between 7 a.m. and 3:30 p.m. Please be advised, this work may be loud and disruptive due to concrete demolition and removal, equipment noise, sound wall construction activities and truck back-up alarms.

While pile driving activity will only be performed during the day, night crews may move equipment to reposition the pile driving rig within the work area. Please be advised this work may be loud and disruptive due to equipment noise, construction lighting (when equipment is moved at night), and vibration and pounding related to pile driving activity.
