Glenarm Street Water Main Infrastructure Improvements Scheduled to Begin June 2024

PASADENA, Calif.— Pasadena Water and Power (PWP) will be replacing a 100-year-old water main along Glenarm Street as part of a major water infrastructure upgrade beginning in June 2024. The project will span from Arroyo Parkway to El Molino Avenue along Glenarm Street. When completed, the upgrades will enhance water service reliability for the area.

To minimize impacts on area residents and businesses, construction efforts will be contained to approximately one block at a time. Occasional, temporary lane closures will happen during work hours. Traffic control signage and flag workers will assist motorists when traffic is temporarily reduced to only one driving lane. Otherwise, at least one driving lane will remain accessible in both directions. Work is scheduled to occur Monday through Friday, 9 a.m. to 4 p.m.

During construction, crews will use a variety of heavy equipment, including excavators, backhoes, loaders, and construction trucks, which may cause some noise and dust in the area. Traffic signs and delineators will be used to minimize the impact of traffic flow along Glenarm Street. PWP asks residents to please observe and adhere to posted no parking zones, construction signs, and flag workers.

Travel lanes will be reduced during phases of construction. Left/right turns will be restricted at certain intersections. In addition, during certain phases of construction, the 110 Freeway on-ramp and off-ramp at Glenarm Street and Arroyo Parkway, will be closed. To expedite travel and access to the 110 FWY, please detour and use Fair Oaks Avenue, or Orange Grove Boulevard on ramps. To expedite east/west travel, please use California Boulevard or Del Mar Boulevard. Please expect traffic delays during construction. Pasadena Transit Route 20 will detour and use Raymond Avenue instead of Arroyo Parkway to avoid delays.

Construction will intermittently affect water service. Notices of any water interruptions will be given at least 48 hours in advance, and special efforts will be taken to keep any other inconveniences to a minimum. For more information, please visit PWP’s website, which will be updated regularly as the project progresses, at or call PWP Water Distribution at (626) 744-4456.
