In addition to the projects listed below that may impact your commute, you can find information on work being done to enhance our City on the Capital Improvement Projects Map and the Road Construction Map.

Traffic Signal Shutdown at Jeffrey Road and Alton Parkway

The traffic signal at the intersection of Jeffrey Road and Alton Parkway will be turned off Monday, May 12, between 9 a.m. and 3 p.m. for traffic signal work. Every effort will be made to keep traffic flowing and minimize disruptions; however, delays should be expected, and motorists should consider using alternate routes.

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 through June 9.

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.

Phase 3 will have a significant impact on the availability of parking near the Civic Center entrance. 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 Irvine Child Development Center will be maintained while work is being done.

The entire project is expected to be completed in July.
