Caltrans construction crews will close all lanes of southbound State Route 163 (SR-163) at Clairemont Mesa Boulevard Friday from 12:01 to 4 a.m. All lanes will reopen before the Friday morning commute.

Motorists will be detoured to westbound State Route 52 to southbound Interstate 805, then to the southbound SR-163 connector ramp

The work is part of a county-wide project to install self-reflective signs that use headlights from highway vehicles to illuminate the sign. The new signs will enhance nighttime visibility and will replace signs requiring light fixtures to light up the signs. Caltrans engineers estimate that the new signs will reduce electrical use by 7 percent.
