To mitigate construction related impacts on traffic, construction begins after 7 a.m. and ends at 3:30 p.m. All traffic lanes remain open, however, before 9 a.m. and after 3 p.m.
Safety First
During construction, the safety of both the public and the workers is the City’s number one priority. To this end, the Irvine Police Department is enforcing a 35 mph speed limit within the Jeffrey Road construction zone. Please help us by adhering to the posted speed limit.
For your safety, bike lanes and the bike trail on Jeffrey Road and along the Metrolink railroad have been close for the duration of the project. Bike detour signs are posted on surrounding streets including Irvine Center Drive, Walnut Avenue, Sand Canyon Road, and Yale Avenue.
We ask that, for your own safety, you stay away from the construction site at all times – even when workers are not present.
