This seismic retrofitting is to help structures withstand earthquakes. Waialae Avenue landscaping will go in under the viaduct near Kahala Mall. Some work likely will start this summer, but few starting dates are firm. Add in water line work on Lunalilo Street, along with resurfacing there and on Ward Avenue, and one might want to avoid those routes during work times. As far as noise goes, it's hoped the loudest work will end at midnight and that only quiet work will go on from then until 4 a.m.
Legislation is in the works to allow nighttime contract work when traffic is light.
The state plans a hot line for residents to call.
