City crews are working this week on constructing new curb ramps and sidewalks at various locations around Diamond Head.

Work will be done at Le'ahi and Monsarrat avenues, Pualei Circle, Makapu'u and Mauna-lei avenues, Paikau and Kaimanahila streets, and along Kahala Avenue and Diamond Head Road.

Crews also will install pavement striping and markings and upgrade some traffic signals.

Work will be done between 8:30 a.m. and 3:30 p.m.

The project should be completed by July, city officials said.
