FLORENCE AVENUE INTERCHANGE PROJECT Drainage system installation and construction along Longworth Avenue between Harvest Avenue and Orr and Day Road (adjacent to northbound I-5), is tentatively scheduled to begin the week of January 23, weather permitting. Work will be conducted weekdays between 6:30 a.m. and 3:30 p.m. and is expected to take one to two weeks to complete. Crews will be performing signal work at Florence Avenue and Orr and Day Road, intermittently over the next two weeks, weekdays between 9 a.m. and 3 p.m. This work will require lane reductions on Florence Avenue at Orr and Day Road; please expect delays and use an alternate route if possible.
