Diamond Bar – There are two major utility upgrade projects in progress, aimed at improving service delivery reliability.  The projects – which began on Jan. 28 – include the installation of new SCE electrical circuits, and replacement of a deteriorated vault; and the replacement of a Gas Company 3” gas main with a 4” line to accommodate the South Coast Air Quality Management District’s operations.

Construction will be carried out in phases, with various road closures and cautionary detours.  Please note the following traffic concerns, and make time allowances or avoid these areas altogether, if possible, during construction times.

• The eastbound right-turn lane along Grand Ave. will be closed for approximately three weeks beginning Feb. 17.
• The #2 eastbound through lane along Grand Ave. will be intermittently closed on weeknights from 8 pm to 5 a.m., and fully closed on weekends from Feb. 17 to Mar. 2.
• One through lane along Golden Springs Dr. will be closed from Copley Dr. to Grand Ave. for one week beginning mid-February.
• One through lane along Golden Springs Dr., as well as two right-turn lanes near Grand Ave. will be closed for two weeks beginning late February.

Both projects are scheduled to be completed on or before March 2.
