SAN DIEGO —Full closures on Interstate 5 (I-5) along with multiple connector closures along I-5 will take place countywide this weekend to replace overhead signs, according to Caltrans.

Crews will close both directions of I-5 at each end of the Local Bypass in the Carmel Valley area Sunday at 3-6 a.m. Traffic will be detoured onto the local bypass at the closure points.

Motorists traveling on the northbound Interstate 805 connector to northbound I-5 will also be detoured onto the Local Bypass.

The following connector closures will take place Saturday and Sunday nights at 11:30 until 4:30 in the morning:

  • Northbound I-5 to State Route 75 (SR-75)
  • Northbound I-5 to State Route 163
  • Southbound State Route 15 (SR-15) to northbound I-5
  • Northbound SR-75 to southbound I-5
  • Westbound State Route 94 to northbound I-5

Advance warning signs will be posted to alert motorists about the closures.

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 seven percent.

Caltrans reminds drivers to ‘Be Work Zone Alert’ by avoiding distracted driving, paying constant attention to traffic, and slowing down when approaching work zones.
