Campus Drive Closure for CicloIrvine: An Open Streets Event

Campus Drive will be closed to vehicles between University Drive and Culver Drive Saturday, May 3, between 5 a.m. and 8 p.m. for the second annual CicloIrvine: An Open Streets Event.

Harvard Avenue and designated cross streets — Bridge Road, Berkeley Avenue, and California Avenue — will remain open to provide access to businesses and shopping centers.

Most driveways along the route will be closed from 5 a.m. to 8 p.m. Please look for posted signs indicating detour routes.

There will be no street parking along the route. There will be free parking at the following locations.

• UCI Social Sciences Parking Structure, 4502 Campus Drive
• UCI Lot 1, adjacent to the parking structure

CicloIrvine highlights the City’s commitment to community engagement, sustainability, and environmentally conscious travel, with 1.4 miles of City streets closed to cars and open for people to stroll, bike, and roll. Experience Irvine’s public spaces and local businesses in a new and reimagined way with live music, art, and engaging activities for all.

Civic Center Parking Lot Rehabilitation

The City continues to make improvements to the Civic Center Parking Lot, with Phase 3 continuing through the next few weeks.

Phase 3 work will be shifting to the northern lot and will temporarily remove access to the main drive-through lane from Harvard beginning Thursday, May 8.

Phase 3 improvements include:

• Construction of landscape islands at the end of each row along the main drive-through lane from Harvard. These areas affect grading and drainage and need to be installed before the irrigation and solar system conduits.
• Upgrading the accessibility path in front of the Civic Center. This work will block off the accessibility path to the Civic Center for one week beginning Thursday, May 1.

Phase 3 will have a significant impact on the availability of parking near the Civic Center entrance for approximately the next four weeks, weather permitting. Work will be done Monday through Saturday from 7 a.m. to 7 p.m. Additional parking is available off of Harvard Avenue and San Juan.

Access to City Hall and ICDC will be maintained while work is being done.

The entire project is expected to be completed in July.
