Michelson Force Main Sewer Improvements

Michelson Force Main Sewer Improvements


Irvine Ranch Water District contractors will be upgrading the sewer line that runs along Michelson Drive from Jamboree Road east beyond Riparian View. Traffic will be heavily impacted by lane closures at construction areas as work is underway.

The project began construction in December 2018, and following some project- and weather-related delays is now scheduled for completion in September, 2019.

Construction hours:


• From 9 a.m. to 3 p.m. Mondays through Fridays.

• From 5 a.m. to 5 p.m. Saturdays.


• Intermittently from 9 p.m. Fridays to 5 a.m. Saturdays.

Where: Construction will occur mostly in the eastbound lanes of Michelson Avenue between Jamboree Road and Riparian View.

Project impacts:

• Traffic lanes will be closed at the various construction zones while work is being performed at each respective location. Morning and lunch-hour traffic is expected to be severe. Motorists are advised to use alternative routes, to access the 405 freeway via Culver Drive, and to enter Michelson Drive from Harvard Avenue.

• Bus stops (marked in blue on the map above) may be periodically closed.

• Bicyclists and motorists will be required to share the road in construction areas.

Questions: Please contact IRWD’s Public Affairs Department at info@irwd.com or 949-453-5500 during business hours. After-hours questions should be directed to the customer service line at 949-453-5300.
